All notable changes for each version of this project will be documented in this file.

22.0.0

New Features

Theming
- Added derived themes for the Grid and related internal components. When a parent component theme is included, its internal controls now derive their tokens from the parent theme colors, keeping nested buttons, icons, inputs, dropdowns, checkboxes, scrollbars, chips, and other helper components visually aligned.
- The derived themes are introduces for the following components:
  - Grid
  - Excel Filtering
  - Grid Toolbar
  - Paginator
  - Column Actions
  - Query Builder and Advanced Filtering Dialog
- The derived themes are applied through the existing component theme mixins, so no additional mixin call is required. To style the whole IgxGrid, provide the $background, $foreground, and $accent-color properties to grid-theme() and include the generated theme with tokens(). The $foreground property is optional; when omitted, it is derived automatically as a contrast color for the background. Internal components inherit derived tokens from the parent component theme.
You can also style each compound component inside the grid with its own theme by providing the same color properties. The generated tokens are scoped to that component and affect the nested controls inside it.
```
    $grid-theme: grid-theme(
        $schema: $schema,
        $background: #ffffff,
        $foreground: #1f2937,
        $accent-color: #0061a8
    );

    $excel-filtering-theme: excel-filtering-theme(
        $schema: $schema,
        $background: #ff2323,
        $accent-color: #21fc9a
    );

    $query-builder-theme: query-builder-theme(
        $schema: $schema,
        $background: #f235ff,
        $accent-color: #89a800
    );

    $grid-toolbar-theme: grid-toolbar-theme( ... );

    $paginator-theme: paginator-theme( ... );

    $column-actions-theme: column-actions-theme( ... );

    igx-grid {
        @include tokens($grid-theme);
    }

    igx-grid-excel-style-filtering,
    .igx-excel-filter__secondary {
        @include tokens($excel-filtering-theme);
    }

    igx-advanced-filtering-dialog {
        @include tokens($query-builder-theme);
    }

    ...
```
- Added a dedicated excel-filtering-theme() for styling the Excel Style Filtering. Use it instead of the excel-filtering color properties from grid-theme().

21.2.0

New Features

IgxOverlayService
- IgxOverlayService.createAbsoluteOverlaySettings - Added a new overload accepting useContainerStrategy?: boolean as the second parameter. When true, uses ContainerPositionStrategy; otherwise defaults to GlobalPositionStrategy. The previous overload accepting outlet?: IgxOverlayOutletDirective | ElementRef is still supported but deprecated.
IgxSnackbarComponent, IgxToastComponent
- Added a new positioning input property. When set to container, the components is displayed inside its nearest positioned ancestor in place of the now deprecated outlet property .
IgxCombo, IgxSimpleCombo
- Introduced the selectionChanged event for both components. The event is not cancelable and is emitted after the selection is committed and the component state is updated.
- Added disableClear input that allows hiding the clear button even when items are selected. Defaults to false.

General

IgxOverlayService
- Deprecation - The outlet property in OverlaySettings, IgxOverlayOutletDirective, and igxToggleOutlet input on IgxToggleActionDirective are deprecated and will be removed in a future version. As overlay service now integrates the HTML Popover API and prefers rendering content in place / in the top layer, significantly reducing the need for outlet containers, new code should rely on the default in-place / top-layer rendering behavior instead of custom outlet containers.
AI-Assisted Development - Copilot Skill: Generate from Image Design
- Added a new igniteui-angular-generate-from-image-design Copilot Skill that teaches AI coding assistants/agents (e.g., GitHub Copilot, Cursor, Windsurf, Claude, JetBrains AI, etc.) how to implement Angular application views directly from design images (screenshots, mockups, wireframes).
- The skill provides a structured workflow covering image analysis, component discovery via MCP tools (list_components, get_doc), theme generation (create_palette, create_theme, create_component_theme), layout implementation, and visual refinement (set_size, set_spacing, set_roundness).
- Includes reference files:
  - Component Mapping - Maps common UI patterns (dashboards, charts, forms, navigation, data display, gauges) to the most appropriate Ignite UI for Angular component with key properties and decision rules.
  - Gotchas - Documents known pitfalls, component-specific constraints, and corrective patterns to help AI agents avoid common implementation mistakes.
AI-Assisted Development - Copilot Skills improvements
- igniteui-angular-grids skill - Added a new sizing.md reference covering grid and column width/height inputs, percentage and auto sizing modes, column sizing (minWidth, maxWidth, * star-sizing, auto-fit), and cell spacing/density control.
- igniteui-angular-components skill - Corrected Financial Chart (IgxFinancialChartComponent) documentation: updated chartType enum values to Auto, Candle, Line, Bar, Column to match the actual FinancialChartType API.
- igniteui-angular-theming skill - Minor cleanup to remove stale internal contributing reference.

21.1.3

Security Fixes

Bumped jspdf dependency to 4.2.1 to address a security vulnerability present in earlier versions.

Added customFont property to IgxPdfExporterOptions for Unicode character support in PDF exports. By default, the PDF exporter uses Helvetica, which only supports basic Latin characters. When exporting data containing non-Latin characters (Cyrillic, Chinese, Japanese, Arabic, Hebrew, special symbols, etc.), you can now provide a custom TrueType font (TTF) with the required character glyphs.

import { IgxPdfExporterService, IgxPdfExporterOptions } from 'igniteui-angular/grids/core';
import { NOTO_SANS_REGULAR, NOTO_SANS_BOLD } from './fonts/noto-sans';

constructor(private pdfExporter: IgxPdfExporterService) {}

exportWithUnicodeSupport() {
    const options = new IgxPdfExporterOptions('GridExport');
    options.customFont = {
        name: 'NotoSans',
        data: NOTO_SANS_REGULAR,  // Base64-encoded TTF font data
        bold: {
            name: 'NotoSans-Bold',
            data: NOTO_SANS_BOLD  // Optional: Base64-encoded bold TTF font data
        }
    };
    
    this.pdfExporter.export(this.grid, options);
}

Key features:

Supports any TrueType font (TTF) provided as Base64-encoded data
Optional bold font variant for header styling
Automatic fallback to Helvetica if custom font loading fails
Works with all grid types (IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid)

IgxTooltipTarget
- Added new properties:
  - showTriggers - Which event triggers will show the tooltip. Expects a comma-separated string of different event triggers. Defaults to pointerenter.
  - hideTriggers - Which event triggers will hide the tooltip. Expects a comma-separated string of different event triggers. Defaults to pointerleave and click.
```
<igx-icon [igxTooltipTarget]="tooltipRef" [showTriggers]="'click,focus'" [hideTriggers]="'keypress,blur'">info</igx-icon>
<span #tooltipRef="tooltip" igxTooltip>Hello there, I am a tooltip!</span>
```
IgxNavigationDrawer - Integrated HTML Popover API to place overlay elements when not pinned in the top layer, eliminating z-index stacking issues.
IgxOverlayService
- Integrated HTML Popover API into the overlay service for improved z-index management and layering control.
- The overlay service now uses the Popover API to place overlay elements in the top layer, eliminating z-index stacking issues.
- Improved positioning accuracy for container-based overlays with fixed container bounds.
AI-Assisted Development - Copilot Skills
- Three consolidated Copilot Skills are now included in the repository to teach AI coding assistants/agents (e.g., GitHub Copilot, Cursor, Windsurf, Claude, JetBrains AI, etc.) how to work with Ignite UI for Angular:
  - Components - UI Components (form controls, layout, data display, feedback/overlays, directives — Input Group, Combo, Select, Date/Time Pickers, Calendar, Tabs, Stepper, Accordion, List, Card, Dialog, Snackbar, Button, Ripple, Tooltip, Drag and Drop, Layout Manager, Dock Manager and Charts (Area Chart, Bar Chart, Column Chart, Stock/Financial Chart, Pie Chart))
  - Data Grids - Data Grids (grid type selection, column config, sorting, filtering, selection, editing, grouping, paging, remote data, state persistence, Tree Grid, Hierarchical Grid, Grid Lite, Pivot Grid)
  - Theming & Styling - Theming & Styling (includes MCP server setup for live theming tools)
- These skills are automatically discovered when placed in the agent's skills path ( e.g. .claude/skills) and this release ships with an optional migration to add those to your project. For more information, see the README.

Added IgxGridLiteComponent wrapper around the igc-grid-lite Web Component (in Developer Preview)

Available from the igniteui-angular/grids/lite entry point. The wrapper component adds Angular-friendly API with similar inputs, including two-way bindable sortingExpressions and filteringExpressions, Angular template-based cell and header rendering with declarative templates via the igxGridLiteCell and igxGridLiteHeader directives.

npm i igniteui-grid-lite

import { IgxGridLiteComponent, IgxGridLiteColumnComponent, IgxGridLiteHeaderTemplateDirective, IgxGridLiteCellTemplateDirective } from "igniteui-angular/grids/lite";

@Component({
    selector: 'app-grid-lite-sample',
    templateUrl: 'grid-lite.sample.html',
    imports: [IgxGridLiteComponent, IgxGridLiteColumnComponent, IgxGridLiteHeaderTemplateDirective, IgxGridLiteCellTemplateDirective]
})
export class GridLiteSampleComponent { }

<igx-grid-lite [data]="data">
    <igx-grid-lite-column field="name" header="Name" [sortable]="true">
        <ng-template igxGridLiteCell let-value>
            <strong>{{ value }}</strong>
        </ng-template>
    </igx-grid-lite-column>
</igx-grid-lite>

General

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid
- Improved performance by dynamically adjusting the scroll throttle based on the data displayed in grid.
IgxCombo, IgxSimpleCombo
- Combo and Simple Combo now close the dropdown list and move the focus to the next focusable element on "Tab" press and clear the selection if the combo is collapsed on "Escape".

Breaking Changes

igxForOf, igxGrid, igxTreeGrid, igxHierarchicalGrid, igxPivotGrid
- original data array mutations (like adding/removing/moving records in the original array) are no longer detected automatically. Components need an array ref change for the change to be detected.
IgxGridGroupByAreaComponent has moved from the grids/core to the grids/grid entry point. The ng update migration will prompt you to optionally migrate your imports to the new entry point.

Localization(i18n)

IgxActionStrip, IgxBanner, IgxCalendar, IgxCarousel, IgxChip, IgxCombo, IgxDatePicker, IgxDateRangePicker, IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid, IgxInputs, IgxList, IgxPaginator, IgxQueryBuilder, IgxTimePicker, IgxTree
- New Intl implementation for all currently supported components that format and render data like dates and numbers.
- New localization implementation for the currently supported languages for all components that have resource strings in the currently supported languages.
- New public localization API and package named igniteui-i18n-resources containing the new resources that are used in conjunction.
- Added API to toggle off Angular's default formatting completely in favor of the new Intl implementation. Otherwise Intl will be used when a locale is not defined for Angular to use.
- Old resources and API should still remain working and not experience any change in behavior, despite internally using the new localization as well.

21.0.0

New Features

New component IgxChat:
- A component that provides complete solution for building conversational interfaces in your applications. Read up more information in the ReadMe
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Added PDF export functionality to grid components. Grids can now be exported to PDF format alongside the existing Excel and CSV export options.
  
  The new IgxPdfExporterService follows the same pattern as Excel and CSV exporters:
```
import { IgxPdfExporterService, IgxPdfExporterOptions } from 'igniteui-angular';

constructor(private pdfExporter: IgxPdfExporterService) {}

exportToPdf() {
    const options = new IgxPdfExporterOptions('MyGridExport');
    options.pageOrientation = 'landscape'; // 'portrait' or 'landscape' (default: 'landscape')
    options.pageSize = 'a4'; // 'a3', 'a4', 'a5', 'letter', 'legal', etc.
    options.fontSize = 10;
    options.showTableBorders = true;
    
    this.pdfExporter.export(this.grid, options);
}
```
  The grid toolbar exporter component now includes a PDF export button:
```
<igx-grid-toolbar>
    <igx-grid-toolbar-exporter 
        [exportPDF]="true" 
        [exportExcel]="true" 
        [exportCSV]="true">
    </igx-grid-toolbar-exporter>
</igx-grid-toolbar>
```
  Key features:
  - Multi-page support with automatic page breaks
  - Hierarchical visualization for TreeGrid (with indentation) and HierarchicalGrid (with child tables)
  - Multi-level column headers (column groups) support
  - Summary rows with proper value formatting
  - Text truncation with ellipsis for long content
  - Landscape orientation by default (suitable for wide grids)
  - Internationalization support for all 19 supported languages
  - Respects all grid export options (ignoreFiltering, ignoreSorting, ignoreColumnsVisibility, etc.)

Breaking Changes

IgxButton
- The following shadow-related parameters were removed from the outlined-button-theme and flat-button-theme:
  - resting-shadow
  - hover-shadow
  - focus-shadow
  - active-shadow

Dependency Injection Refactor

All internal DI now uses the inject() API across igniteui-angular (no more constructor DI in library code).
If you extend our components/services or call their constructors directly, remove DI params and switch to inject() (e.g., protected foo = inject(FooService);).
App usage via templates remains the same; no action needed unless you subclass/override our types.

Multiple Entry Points Support

The library now supports multiple entry points for better tree-shaking and code splitting. While the main entry point (igniteui-angular) remains fully backwards compatible by re-exporting all granular entry points, we recommend migrating to the new entry points for optimal bundle sizes.

Entry Points:

igniteui-angular/core - Core utilities, services, and base types
igniteui-angular/directives - Common directives
Component-specific entry points: igniteui-angular/grids, igniteui-angular/input-group, igniteui-angular/drop-down, etc.
Grid-specific entry points for tree-shakable imports:
- igniteui-angular/grids/core - Shared grid infrastructure (columns, toolbar, filtering, sorting, etc.)
- igniteui-angular/grids/grid - Standard grid component (IgxGridComponent)
- igniteui-angular/grids/tree-grid - Tree grid component (IgxTreeGridComponent)
- igniteui-angular/grids/hierarchical-grid - Hierarchical grid component (IgxHierarchicalGridComponent, IgxRowIslandComponent)
- igniteui-angular/grids/pivot-grid - Pivot grid component (IgxPivotGridComponent, IgxPivotDataSelectorComponent)

Migration: The ng update migration will prompt you to optionally migrate your imports to the new entry points. If you choose not to migrate, you can continue using the main entry point with full backwards compatibility.

To migrate manually later:

ng update igniteui-angular --migrate-only --from=20.1.0 --to=21.0.0

Component Relocations:

Input directives (IgxHintDirective, IgxInputDirective, IgxLabelDirective, IgxPrefixDirective, IgxSuffixDirective) → igniteui-angular/input-group
IgxAutocompleteDirective → igniteui-angular/drop-down
IgxRadioGroupDirective → igniteui-angular/radio

Type Renames (to avoid conflicts):

Direction → CarouselAnimationDirection (in carousel)

Benefits:

Better tree-shaking - unused components won't be bundled
Code splitting - each component can be lazy-loaded separately
Smaller bundle sizes - import only what you need
Improved build performance

See the Angular Package Format documentation for more details on entry points.

20.1.0

New Features

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Introduced a new cell merging feature that allows you to configure and merge cells in a column based on same data or other custom condition, into a single cell.
  
  It can be enabled on the individual columns:
```
<igx-column field="field" [merge]="true"></igx-column>
```
  The merging can be configured on the grid level to apply either:
  - onSort - only when the column is sorted.
  - always - always, regardless of data operations.
```
<igx-grid [cellMergeMode]="'always'">
</igx-grid>
```
  The default cellMergeMode is onSort.
  
  The functionality can be modified by setting a custom mergeStrategy on the grid, in case some other merge conditions or logic is needed for a custom scenario.
  
  It's possible also to set a mergeComparer on the individual columns, in case some custom handling is needed for a particular data field.
- Added ability to pin individual columns to a specific side (start or end of the grid), so that you can now have pinning from both sides. This can be done either declaratively by setting the pinningPosition property on the column:
```
<igx-column [field]="'Col1'" [pinned]='true' [pinningPosition]='pinningPosition'>
</igx-column>
```
```
public pinningPosition = ColumnPinningPosition.End;
```
  Or with the API, via optional parameter:
```
grid.pinColumn('Col1', 0, ColumnPinningPosition.End);
grid.pinColumn('Col2', 0, ColumnPinningPosition.Start);
```
  If property pinningPosition is not set on a column, the column will default to the position specified on the grid's pinning options for columns.
IgxCarousel
- Added select method overload accepting index.
```
this.carousel.select(2, Direction.NEXT);
```
IgxDateRangePicker
- Now has a complete set of properties to customize the calendar:
  - headerOrientation
  - orientation
  - hideHeader
  - activeDate
  - disabledDates
  - specialDates
- As well as the following templates, available to customize the contents of the calendar header in dialog mode:
  - igxCalendarHeader
  - igxCalendarHeaderTitle
  - igxCalendarSubheader
- Added new properties:
  - usePredefinedRanges - Whether to render built-in predefined ranges
  - customRanges - Allows the user to provide custom ranges rendered as chips
  - resourceStrings - Allows the user to provide set of resource strings
- Behavioral Changes
  - Added cancel button to the dialog, allowing the user to cancel the selection.
  - The calendar is displayed with header in dialog mode by default.
  - The picker remains open when typing (in two-inputs and dropdown mode).
  - The calendar selection is updated with the typed value.
  - The calendar view is updated as per the typed value.
  - The picker displays a clear icon by default in single input mode.
- IgxPredefinedRangesAreaComponent
  - Added new component for rendering the predefined or custom ranges inside the calendar of the IgxDateRangePicker
IgxDatePicker
- Similar to the IgxDateRangePicker, also completes the ability to customize the calendar by introducing the following properties in addition to the existing ones:
  - hideHeader
  - orientation
  - activeDate
- Behavioral Changes
  - The calendar selection is updated with the typed value.
  - The calendar view is updated as per the typed date value.
IgxOverlay
- Position Settings now accept a new optional offset input property of type number. Used to set the offset of the element from the target in pixels.
IgxTooltip
- The tooltip now remains open while interacting with it.
IgxTooltipTarget
- Introduced several new properties to enhance customization of tooltip content and behavior. Those include positionSettings, hasArrow, sticky, closeButtonTemplate. For detailed usage and examples, please refer to the Tooltip README.

General

IgxDropDown now exposes a role input property, allowing users to customize the role attribute based on the use case. The default is listbox.
IgxTooltipTarget
- Behavioral Changes
  - The showDelay input property now defaults to 200.
  - The hideDelay input property now defaults to 300.
  - The showTooltip and hideTooltip methods do not take showDelay/hideDelay into account.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid
- Sorting improvements
  - Improved sorting algorithm efficiency using Schwartzian transformation. This is a technique, also known as decorate-sort-undecorate, which avoids recomputing the sort keys by temporarily associating them with the original data records.
  - Refactored sorting algorithms from recursive to iterative.
- Groupby improvements
  - Refactored grouping algorithm from recursive to iterative.
  - Optimized grouping operations.

20.0.6

General

IgxSimpleCombo
- Added disableFiltering to the IgxSimpleCombo, which enables/disables the filtering in the list. The default is false.
IgxCombo, IgxSimpleCombo
- Removed deprecated filteringOptions.filterable option.

20.0.2

New Features

Separating Button and Icon Button Themes - The button-theme and icon-button-theme functions are still available, but for more targeted customization, you can now use the specific theme function for each button type.
Component Themes Enchancements - Component themes have been improved to automatically calculate all necessary states (e.g., hover, focus, active) based on just a few key values. For example, customizing a contained button requires only a background color:

    $custom-contained-button: contained-button-theme(
        $background: #09f;
    );

20.0.0

General

Angular 20 Compatibility - Ignite UI for Angular now plays nice with Angular 20! Upgrade your apps and enjoy the latest features.
IgxActionStrip
- Behavioral Changes - When using the Action Strip standalone, outside of Grid, scenarios the component is no longer initially visible and the hidden property now defaults to true.
IgxChip
- Behavioral Change The variant is now strictly typed with the union of supported options and no longer accepts invalid values for the default state, provide no value (nullish) instead is needed.

New Features

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid
- Added a new igxGridEmpty template directive that allows assigning the emptyGridTemplate declaratively, without the need to get and assign reference, like other grid templates like:
```
<igx-grid>
  <ng-template igxGridEmpty>
    
  </ng-template>
</igx-grid>
```
- Added a new igxGridLoading template directive that allows assigning the loadingGridTemplate declaratively, without the need to get and assign reference, like other grid templates like:
```
<igx-grid>
  <ng-template igxGridLoading>
    
  </ng-template>
</igx-grid>
```

19.2.0

General

IgxCarousel
- Removed deprecated property keyboardSupport.
IgxSlide
- Deprecation - tabIndex has been deprecated and will be removed in a future version.
IgxGrid, IgxHierarchicalGrid, IgxTreeGrid
- A column's minWidth and maxWidth constrain the user-specified width so that it cannot go outside their bounds.
- In SSR mode grid with height 100% or with no height will render on the server with % size and with no data. The grid will show either the empty grid template or the loading indicator (if isLoading is true).
- In SSR mode grid with width 100% or with no width will render on the server with % size and with all columns.
- The pagingMode property can now be set as simple strings 'local' and 'remote' and does not require importing the GridPagingMode enum.
IgxHierarchicalGrid
- Introduced a new advanced filtering capability that enables top-level records to be dynamically refined based on the attributes or data of their associated child records.
- Added a new schema input property that can be used to pass collection of EntityType objects. This property is required for remote data scenarios.
IgxQueryBuilderComponent, IgxAdvancedFilteringDialogComponent
- Added support for entities with hierarchical structure.
EntityType
- A new optional property called childEntities has been introduced that can be used to create nested entities.

19.1.1

New Features

IgxListItem
- Added a new selected input property, making it easier to indicate when a list item is selected by applying styling responsible for that state.

19.1.0

General

IgxCarousel
- Behavioral Changes - the maximumIndicatorsCount input property now defaults to 10.
- Deprecation - CarouselIndicatorsOrientation enum members top and bottom have been deprecated and will be removed in a future version. Use start and end instead.

New Features

IgxBanner
- Introduced a new expanded input property, enabling dynamic control over the banner's state. The banner can now be programmatically set to expanded (visible) or collapsed (hidden) both initially and at runtime. Animations will trigger during runtime updates — the open animation plays when expanded is set to true, and the close animation plays when set to false. However, no animations will trigger when the property is set initially.
- The banner's event lifecycle (opening, opened, closing, closed) only triggers through user interactions (e.g., clicking to open/close). Programmatic updates using the expanded property will not fire any events.
- If the expanded property changes during an ongoing animation, the current animation will stop and the opposite animation will begin from the point where the previous animation left off. For instance, if the open animation (10 seconds) is interrupted at 6 seconds and expanded is set to false, the close animation (5 seconds) will start from its 3rd second.
IgxQueryBuilder has a new design that comes with an updated appearance and new functionality
- IgxQueryBuilderComponent
  - Introduced the ability to create nested queries by specifying IN/NOT IN operators.
  - Introduced the ability to reposition condition chips by dragging or using Arrow Up/Down.
  - Added the entities property that accepts an array of EntityType objects describing an entity with its name and an array of fields. The fields input property has been deprecated and will be removed in a future version. Automatic migrations are available and will be applied on ng update.
  - Added disableEntityChange property that can be used to disable the entity select on root level after the initial selection. Defaults to false.
  - Added disableReturnFieldsChange property that can be used to disable the fields combo on root level. Defaults to false.
  - Added the canCommit, commit and discard public methods that allows the user to save/discard the current state of the expression tree.
  - Added option to template the search value input:
```
<ng-template igxQueryBuilderSearchValue
            let-searchValue
            let-selectedField = "selectedField"
            let-selectedCondition = "selectedCondition"
            let-defaultSearchValueTemplate = "defaultSearchValueTemplate">
    @if (selectedField?.field === 'Id' && selectedCondition === 'equals'){
        <input type="text" required [(ngModel)]="searchValue.value"/>
    } @else {
        <ng-container #defaultTemplate *ngTemplateOutlet="defaultSearchValueTemplate"></    ng-container>
    }
</ng-template>
```
  - Behavioral Changes
  - Expression enters edit mode on single click, Enter or Space.
  - Selecting conditions inside the IgxQueryBuilderComponent is no longer supported. Grouping/ungrouping expressions is now achieved via the newly exposed Drag & Drop functionality.
  - Deleting multiple expressions through the context menu is no longer supported.
- IgxQueryBuilderHeaderComponent
  - Behavioral Change
  - Legend is no longer shown.
  - If the title input property is not set, by default it would be empty string.
  - Deprecation
  - The showLegend and resourceStrings input properties have been deprecated and will be removed in a future version. Automatic migrations are available and will be applied on ng update.
IFilteringExpression
- A new optional property called conditionName has been introduced. This would generally be equal to the existing condition.name.
IFilteringOperation
- A new optional property called isNestedQuery has been introduced. It's used to indicate whether the condition leads to a nested query creation.

19.0.0

General

IgxFilteringService, IgxGridBaseDirective
- Deprecation The filterGlobal method has been deprecated and will be removed in a future version.

New Features

IgxColumn
- Introduced the disabledSummaries property, allowing users to specify which summaries should be disabled for a given column. This property accepts an array of strings corresponding to the summary keys, enabling selective control over both default summaries (e.g., 'Count', 'Min') and any custom summaries created by the user.
Themes
- Deprecation The utility mixins light-theme, dark-theme, bootstrap-light-theme, bootstrap-dark-theme, fluent-light-theme, fluent-dark-theme, indigo-light-theme, and indigo-dark-theme have been deprecated and will be removed in version 20 of Ignite UI for Angular. Switch to the more generic theme mixin instead. Example:
```
$my-light-palette: palette(
    $primary: navy,
    $secondary: rebeccapurple,
    $surface: white,
);

// Before:
@include light-theme(
    $palette: $my-light-palette
);

// After:
@include theme(
    $palette: $my-light-palette,
    $schema: $light-material-schema,
);
```

18.2.0

General

IFilteringExpressionsTree, FilteringExpressionsTree
- Deprecation The find and findIndex methods have been deprecated and will be removed in a future version. A ExpressionsTreeUtil class has been added which provides the same functionality.

New Features

IgxSimpleCombo
- Introduced ability for Simple Combo to automatically select and retain valid input on "Tab" press enhancing user experience by streamlining data entry and reducing the need for manual selection improving form navigation.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- To streamline the sorting of columns with custom formats, a new FormattedValuesSortingStrategy has been introduced. This strategy simplifies the sorting process by allowing direct sorting based on formatted values, eliminating the need to extend the DefaultSortingStrategy or implement a custom ISortingStrategy. This enhancement improves the ease of handling sorting with custom column formatters.
IgxCarousel
- Added support for vertical alignment. Can be configured via the vertical property. Defaults to false.
- Added support for showing/hiding the indicator controls (dots). Can be configured via the indicators property. Defaults to true.
ColumnType, IgxColumn
- The built-in editors for columns of type date, dateTime and time now use a default input format as per the IgxGrid's locale. This is valid both for cell editors and the ones in the filtering UI for all modes - quickFilter, excelStyle and the Advanced filtering.
- In case the pipeArgs.displayFormat property of a date-time column is set and contains only numeric date-time parts or such that can be handled by the editors, the built-in editors input format is inferred from it.
- To configure the built-in editors, a new editorOptions property is added that allows to pass optional parameters. Accepts an IColumnEditorOptions object with the dateTimeFormat property, that is used as input format for the editors of date, dateTime and time column data types:
```
    const editorOptions: IColumnEditorOptions = { Field?
        dateTimeFormat: 'MM/dd/YYYY',
    }
```
```
    <igx-column field="sampleDate" dataType="date" [editorOptions]="editorOptions"></igx-column>
```
FieldType (IgxQueryBuilder)
- Similar to the above, the fields now accept an editorOptions object of type IFieldEditorOptions. Its dateTimeFormat property is used as input format for the query editors of date-time fields.
IgxDateTimeEditor, IgxDatePicker, IgxTimePicker, IgxDateRangePicker
- In case the inputFormat property is not set, the input format is inferred from displayFormat if set and if it contains only numeric date-time parts.
IgxTimePicker
- The input and display formats are now adjusted based on the locale. For instance, day period time part (AM/PM or a/p) would not be displayed for locales that do not require it.
IgxDateTimeEditor
- Added a new defaultFormatType property (date | time | dateTime) which configures the date-time parts according to the target type that the editor mask includes. Defaults to date.
IgxTabs
- Added activation property to control tab selection. In auto mode (default), tabs are selected instantly with Arrow or Home/End keys. In manual mode, tabs are focused with keys but only selected with Enter or Space.
IgxGridState
- When possible the state directive nows reuses the column that already exists on the grid when restoring the state, instead of creating new column instances every time. This removes the need to set any complex objects manually back on the column on columnInit. The only instance where this is still necessary is when the column (or its children in case of column groups) have no field property so there's no way to uniquely identify the matching column.
- Added support for persisting Multi-Row Layout.

Themes

Breaking Change Palettes
- All palette colors have been migrated to the CSS relative colors syntax. This means that color consumed as CSS variables no longer need to be wrapped in an hsl function.
Example:
```
/* 18.1.x and before: */
background: hsl(var(--ig-primary-600));

/* 18.2.0+: */
background: var(--ig-primary-600);
```
This change also opens up the door for declaring the base (500) variants of each color in CSS from any color, including other CSS variables, whereas before the Sass palette function was needed to generate color shades from a base color.

Example:
```
/* 18.1.x and before: */
$my-palette: palette($primary: #09f, ...);

/* 18.2.0+: */
--ig-primary-500: #09f;
```
This change adds to our continuous effort to make theming configurable in CSS as much as it is in Sass.

Scrollbar: New CSS variables

We have introduced new CSS variables to allow for more customizable scrollbars. This enhancement utilizes the available WebKit pseudo-selectors such as ::-webkit-scrollbar-track. However, please note that these pseudo-selectors are prefixed with -webkit- and are only supported in WebKit-based browsers (e.g., Chrome, Safari).

List of Available CSS Variables for `-webkit-` browsers:

--sb-size: Adjusts the scrollbar size (width and height).
--sb-track-bg-color: Sets the background color of the scrollbar track.
--sb-track-bg-color-hover: Sets the background color of the scrollbar track on hover.
--sb-thumb-min-height: Sets the minimum height of the scrollbar thumb.
--sb-thumb-border-radius: Sets the border radius of the scrollbar thumb.
--sb-thumb-border-size: Sets the border size of the scrollbar thumb.
--sb-thumb-border-color: Sets the border color of the scrollbar thumb.
--sb-thumb-bg-color: Sets the background color of the scrollbar thumb.
--sb-thumb-bg-color-hover: Sets the background color of the scrollbar thumb on hover.

For Firefox users, we provide limited scrollbar styling options through the following CSS variables:

--sb-size: Adjusts the scrollbar size.
--sb-thumb-bg-color: Sets the background color of the scrollbar thumb.
--sb-track-bg-color: Sets the background color of the scrollbar track.

General

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid
- Deprecation The shouldGenerate property has been deprecated and will be removed in a future version. Column re-creation now relies on autoGenerate instead. Automatic migration to this is available and will be applied on ng update. Note that if autoGenerate is already set initially, there is no need to explicitly set it elsewhere in your code.
IgxCarousel
- animationType input property is now of type CarouselAnimationType. HorizontalAnimationType can also be used, however, to accommodate the new vertical mode, which supports vertical slide animations, it is recommended to use CarouselAnimationType.
- Behavioral Changes - the keyboardSupport input property now defaults to false.
- Deprecation - the keyboardSupport input property has been deprecated and will be removed in a future version. Keyboard navigation with ArrowLeft, ArrowRight, Home, and End keys will be supported when focusing the indicators' container via Tab/Shift+Tab.
IgxCombo:
- Breaking Change The deprecated filterable property is replaced with disableFiltering.
- The dropdown search field placeholder is now part of the Combo's localization resources. It now also uses two resource values depending on whether filtering is active, e.g. in the default en locale it remains 'Enter a Search Term', but changes to 'Add Item' when disableFiltering and allowCustomValues are set to true. For that reason, the existing searchPlaceholder input is also deprecated in favor of the resources.
- Deprecation - filterable from the filteringOptions has been deprecated in favor of disableFiltering.
IgxBadge
- Breaking Change The $border-width property has been removed from the badge theme.
- New outlined variant of the badge component has been added. Users can switch to outlined by adding the newly created outlined property to a badge.

18.1.0

New Features

IgxPivotGrid
- Added horizontal layout for row dimensions. Can be configured through the pivotUI rowLayout property.
- Added horizontalSummary property for each IPivotDimension, enabling summary row when using horizontal layout.
- Added horizontalSummariesPosition property to the pivotUI, configuring horizontal summaries position.
- Keyboard navigation now can move in to row headers back and forth from any row dimension headers or column headers.
- Added keyboard interactions for row dimension collapse using Alt + Arrows and row headers sorting using Ctrl + Arrow Up/Down.
IgxIcon, IgxIconService
- You can now register icons by reference via the IgxIconService. To learn more check out the documentation.
- All components now use icons by reference internally so that it's easy to replace them without explicitly providing custom templates.
- registerFamilyAlias has been deprecated in favor of setFamily to allow adding metadata for type and prefix when registering custom icon families. To migrate from registerFamilyAlias, do the following:
```
    this.iconService.registerFamilyAlias('my-family', 'my-family-class');
    this.iconService.setFamily('my-family', { className: 'my-family-class' });
```

General

ColumnType, IgxColumn, IgxColumnGroup, IgxColumnLayout
- The children query property has been deprecated and replaced by childColumns getter directly returning columns array.
- Several properties have been hidden from the public API, considered internal and not recommended for use. Those include: filterCell, headerCell, headerGroup, defaultMinWidth, gridRowSpan, gridColumnSpan and cells.
IgxPaginator
- The isFirstPageDisabled and isLastPageDisabled have been deprecated in favor of the identical isFirstPage and isLastPage getter.
IgxOverlayService
- The attach method overload accepting Type and OverlaySettings now accepts OverlayCreateSettings as second parameter. This interface extends OverlaySettings with an additional injector property used as ElementInjector when creating the dynamic component.

18.0.0

New Features

IgxCombo, IgxSimpleCombo:
- Introduced ability for hiding the clear icon button when the custom clear icon template is empty.
IgxDateTimeEditor, IgxTimePicker:
- Now accept the following custom inputFormat options, as Angular's DatePipe:
  - Fractional seconds: S, SS, SSS.

IgxOverlayService, IgxToggleDirective:
- Added an optional offsetMode parameter to the setOffset method that determines whether to add (by default) or set the offset values using OffsetMode.Add and OffsetMode.Set.

Changes

With the removal of the Display Density token, components now get their default sizes from the theme. Default sizes have changed for most components, with it now being medium (previously large). Here's an exhaustive list of all sizable components and their default sizes by theme:

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Removed the deprecated movable property of IgxColumnComponent.
IgxOverlayService
- Removed the deprecated PositionSettings.target (in favor of general OverlaySettings.target).
- Replaced deprecated attach method overload accepting ComponentFactoryResolver (trough NgModuleRef-like object) with shortcut overload that uses just the root scope and createComponent. The overload accepting ViewComponentRef is still recommended for local injection context.
IgxPivotGrid
- The IgxPivotDateDimension deprecated getters inBaseDimension and inOption have been removed.
IgxSimpleCombo
- Behavioral Change When bound to ngModel and formControlName directives, the model would not be updated when the user types into the input and will only be updated on selection.

17.2.0

New Features

IgxAvatar
- Removed deprecated property roundShape; Deprecated color and bgColor properties.
IgxButton
- Removed deprecated properties color and background;
IgxCalendar
- Completely revamped calendar themes.
- New years view.
- Updated months view.
- Updated keyboard navigation and accessibility.
- Added selection preview in range selection mode.
- Added the ability to change the orientation of the calendar when multiple day views are present.
- Replaced the vertical property with orientation that can be set to either horizontal(default) or vertical.

IgxDialog
- Removed leftButtonColor, leftButtonBackgroundColor rightButtonColor, and rightButtonBackgroundColor properties.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Enhanced the advanced filtering to emit the filtering event when filters are applied.

General

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- The contextMenu event now fires when the end-user clicks to the right of the right-most cell in the grid in case the grid's columns don't span its full width. For this reason the event argument of the event is now of type IGridContextMenuEventArgs which contains the row object as well as the cell one. The latter will be null if the event didn't originate from a cell. This is not a breaking change as the new type extends the old.
IgxSimpleCombo
- Behavioral Change The selectionChanging event will now trigger when typing the first character in the input if there is a previously selected value in the IgxSimpleCombo.
- Behavioral Change Updated behavior to maintain the entered text in the input field upon pressing Enter while the combo input is focused, ensuring uninterrupted focus for continuous filtering. Additionally, the dropdown menu now remains open to display filtered results.

17.1.0

New Features

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Added a new output - rowClick that fires when the user clicks on a row element of the grid, including group rows
IgxTree
- Added new property toggleNodeOnClick that determines whether clicking over a node will change its expanded state or not. Set to false by default.
IgxPivotGrid
- IPivotDimension interface now exposes a property called displayName similar to the one in the IPivotValue interface. This property is optional and will be displayed inside the chips for rows and columns in the IgxPivotGrid. If the displayName property is not set, memberName will be used as a fallback.
IgxHierarchicalGrid, IgxGridToolbar
- The declaration of child layout toolbar templates no longer require explicit grid reference so the following:
```
<igx-row-island>
  <igx-grid-toolbar [grid]="childGrid" *igxGridToolbar="let childGrid">
```
  can be simplified like:
```
<igx-row-island>
  <igx-grid-toolbar *igxGridToolbar>
```
- With this change the grid property of the IgxGridToolbar has been deprecated as it's no longer needed and will be removed in a future version.
New directive - igxIconButton directive that provides a way to use an icon as a fully functional button has been added. The new igxIconButton comes in three types - flat, outlined and contained (default). All igxButton's with type icon will be automatically migrated to the new igxIconButton's with ng update.
IgxButton
- Behavioral Change buttonSelected event is now emitted not only when a button gets selected, but also when it gets deselected. However, the event is no longer being emitted on initialization. If this event was used in a scenario where it is assumed that the button gets selected, it's a good idea the logic to be branched now based on eventArgs.selected condition.
IgxRowIsland
- Added toolbarTemplate and paginatorTemplate inputs for defining IgxGridToolbar and IgxPaginator templates.

General

igxButton:
- Breaking Change The raised type of the igxButton directive has been renamed to contained. Automatic migrations are available and will be applied on ng update.
- The igxButtonColor and igxButtonBackground input properties have been deprecated and will be removed in a future version.
IgxForOf
- Unified logic for vertical and horizontal virtualization such as - caching, updating, max browser size exceeding.
- Added new method - addScroll that can shift the scroll thumb by the specified amount in pixels (negative number to scroll to previous, positive to scroll next). Similar to addScrollTop but works for both vertical and horizontal virtualization.
IgxTextHighlightDirective is now correctly tree-shaken out of the bundle when not used.
- Breaking Change A new IgxTextHighlightService is now exposed and methods setActiveHighlight and clearActiveHighlight have been moved to it.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Tree-shaking of the grids has been improved:
  - The igx-paginator, igx-grid-toolbar and igx-action-strip components should now correctly tree-shake when not used in a grid.
- Breaking Changes
  - rowAdd and rowDelete events now emit event argument of type IRowDataCancelableEventArgs instead of IGridEditEventArgs. The two interfaces are still compatible, however redundant for these events properties cellID, newValue, oldValue, isAddRow are deprecated in IRowDataCancelableEventArgs and will be removed in a future version. Switching to the correct new interfaces should reveal any deprecated use that can be safely removed.
- Deprecations
  - rowID property has been deprecated in the following interfaces: IGridEditDoneEventArgs, IPathSegment, IRowToggleEventArgs, IPinRowEventArgs, IgxAddRowParent and will be removed in a future version. Use rowKey instead.
  - primaryKey property has been deprecated in the following interfaces: IRowDataEventArgs, IGridEditDoneEventArgs. Use rowKey instead.
  - data property has been deprecated in the following interfaces: IRowDataEventArgs. Use rowData instead.
HammerJS is now an optional dependency, which means apps no longer need to install and include it for related components to work. Touch-specific handling on some components is still dependent on HammerJS setup, but will be disabled without. The setup is now also an option when adding Ignite UI for Angular to existing projects via the ng add command.

17.0.0

General

IgxCard
- Breaking Change The type attribute has been deprecated and will be removed in a future version. The default view of the card component is now outlined. Users can switch to elevated view by adding the newly created elevated property to a card.
standalone components support is now official
- added IGX_RADIO_GROUP_DIRECTIVES for IgxRadioGroupDirective and IgxRadioComponent
animations are now imported from igniteui-angular/animations/@infragistics/igniteui-angular/animations
Tree-shaking of the product has been improved
- igniteui-angular-i18n is now tree-shakeable
- igniteui-angular/animations is now tree-shakeable
- igniteui-angular components have improved tree-shaking
- Breaking Change getCurrentResourceStrings has been removed. Use the specific component string imports instead.
  - E.g. EN strings come from igniteui-angular: import { GridResourceStringsEN } from 'igniteui-angular';
  - E.g. DE or other language strings come from igniteui-angular-i18n: import { GridResourceStringsDE } from 'igniteui-angular-i18n';
DisplayDensity token and inputs are deprecated in favor of --ig-size theming
We're working on reducing the library size
- IgxRadioComponent size has been reduced in half
- IgxSwitchComponent size has been reduced in half
IgxRadioComponent
- Breaking Change IChangeRadioEventArgs is now IChangeCheckboxEventArgs. ng update to 17.0.0 will automatically migrate this for you.
- Breaking Change RadioLabelPosition is now LabelPosition. ng update to 17.0.0 will automatically migrate this for you.
IgxSwitchComponent
- Breaking Change IChangeSwitchEventArgs is now IChangeCheckboxEventArgs. ng update to 17.0.0 will automatically migrate this for you.
- Breaking Change SwitchLabelPosition is now LabelPosition. ng update to 17.0.0 will automatically migrate this for you.
IgxCombo
- Breaking Change IComboSelectionChangingEventArgs properties newSelection and oldSelection have been renamed to newValue and oldValue respectively to better reflect their function. Just like Combo's value, those will emit either the specified property values or full data items depending on whether valueKey is set or not. Automatic migrations are available and will be applied on ng update.
- IComboSelectionChangingEventArgs exposes two new properties newSelection and oldSelection in place of the old ones that are no longer affected by valueKey and consistently emit items from Combo's data.
  
  Note: In remote data scenarios with valueKey set, selected items that are not currently part of the loaded data chunk will be emitted a partial item data object with the valueKey property.
- Breaking Change - IComboSelectionChangingEventArgs properties added and removed now always contain data items, regardless of valueKey being set. This aligns them with the updated newSelection and oldSelection properties, including the same limitation for remote data as described above.
IgxSimpleCombo
- Breaking Change - ISimpleComboSelectionChangingEventArgs properties newSelection and oldSelection have been renamed to newValue and oldValue respectively to better reflect their function. Just like Combo's value, those will emit either the specified property value or full data item depending on whether valueKey is set or not. Automatic migrations are available and will be applied on ng update.
- ISimpleComboSelectionChangingEventArgs exposes two new properties newSelection and oldSelection in place of the old ones that are no longer affected by valueKey and consistently emit items from Combo's data.
  
  Note: In remote data scenarios with valueKey set, selected items that are not currently part of the loaded data chunk will be emitted a partial item data object with the valueKey property.
- Breaking Change The value and selection properties now correctly return a single value or data item instead of the same wrapped in array and undefined instead of empty array, matching the values emitted from selection event and when working with formControlName/ngModel directives.
IgxCombo,IgxSimpleCombo
- Breaking Change The displayValue property now returns the display text as expected (instead of display values in array).

16.1.5

General

IgxButtonGroup:
- Reverted cancellable on selected and deselected events (added in 15.1.24) as it was breaking firing order and related handling.

16.1.4

New Features

Themes:

Experimental - Added the ability to configure the base font-size used to calculate the rem values in all component themes. This allows for proper scaling of components when a different document font-size is used.
Code example:

// Configure the base font-size
@use 'igniteui-theming/sass/config' as * with (
    $base-font-size: 10px // <-- 10px == 1rem
);

// Standard imports and theme declarations
@use 'igniteui-angular/src/lib/core/styles/themes' as *;

// This change also adds a new CSS variable `--ig-base-font-size`
// that you can use to configure your own stylesheets:
html {
    font-size: var(--ig-base-font-size); // 10px
}

@include core();
@include typography();
@include theme();

16.1.0

New Features

IgxSelect:

The select component now has the ability to handle igxPrefix and igxSuffix directives inside igx-select-item.

   <igx-select-item>
       <igx-icon igxPrefix>alarm</igx-icon>
       Select item text content
       <igx-icon igxSuffix>alarm</igx-icon>
   </igx-select-item>

IgxBadge:

Material icons extended along with any other custom icon set can now be used inside the badge component.
Code example:

import { IgxBadgeComponent, IgxIconService } from 'igniteui-angular';
import { heartMonitor } from '@igniteui/material-icons-extended';

export class BadgeSampleComponent implements OnInit {
   constructor (protected _iconService: IgxIconService) {}

   public ngOnInit() {
       this._iconService.addSvgIconFromText(heartMonitor.name, heartMonitor.value, 'imx-icons');
   }
}

   <igx-badge icon="heart-monitor" iconSet="imx-icons"></igx-badge>

IgxCombo:
- Exposed comboIgnoreDiacriticsFilter filter function which normalizes diacritics to their base representation. When the combo components are configured with it, filtering for "resume" will match both "resume" and "résumé".
IgxCombo, IgxSimpleCombo
- Added new property displayValue that returns array of display keys.
IgxButtonGroup:
- Added owner to the IButtonGroupEventArgs to identify the emitting button group instance.
- Breaking Change Added the selectionMode property that sets the selection mode of the buttons in the IgxButtonGroup. Selection modes are single, singleRequired and multi as default is single.
- Breaking Change Deprecated the multiSelection property and all references have been migrated to selectionMode="multi".
Themes:
- Include a standalone theme for the igxLabel directive to allow usage with components outside the Input Group.

Changing the size of Ignite UI components can now be done via a new custom CSS property - --ig-size . The DisplayDensityToken injection token and consequently, the displayDensity inputs for all components will be deprecated in the next major version and it is recommended that they no longer be used for sizing components.

Code example:

// *.component.ts
// remove the provider declaration for `DisplayDensityToken`
providers: [{ provide: DisplayDensityToken, useValue: { displayDensity: DisplayDensity.compact } }],

<!-- Remove `[displayDensity]="'compact'"` -->
<igx-grid [displayDensity]="'compact'">...</igx-grid>

/*
Add --ig-size to a component or global file.
Available values are:
compact: --ig-size-small
cosy: --ig-size-medium
comfortable: --ig-size-large
*/
igx-grid {
    --ig-size: var(--ig-size-small);
}

General

IgxStepper:
- Breaking Change The IgxStepSubTitleDirective has been renamed to IgxStepSubtitleDirective. Automatic migrations are available and will be applied on ng update.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- The draggable attribute is no longer required to be set on interactable elements, if a column header is templated and the Column Moving is enabled in order for handlers for any event to be triggered. Now draggable='false' can be used as an addition if the user shouldn't be able to drag a column by that element, but even if omitted click events for example will trigger now.
- Behavioral Change When there are already grouped columns, the group drop area now shows after dragging of a column starts and not when only click actions are performed.
IgxCombo, IgxSimpleCombo:
- Breaking Change The selection property returns an array of the selected items even when a value key is provided and the value property returns an array of value keys instead of display keys. Automatic migrations are available and will be applied on ng update.
Improved tree-shaking support for the @igniteui/material-icons-extended package.
Improved tree-shaking support for the igniteui-angular-i18n package.
Improved tree-shaking support for all grids.

16.0.0

General

All Ignite UI for Angular components are now exported as standalone components. The library still exports NgModules, which have been preserved for backward compatibility, but they no longer declare any of the Ignite UI for Angular components, instead they just import and export the standalone components. The standalone components are still in a preview stage. Some utility directive exports may change in the future and may be missing from the documentation in the initial release, hence the preview state of the feature.

Now you can do:

// IGX_GRID_DIRECTIVES exports all grid related components and directives
import { IGX_GRID_DIRECTIVES } from 'igniteui-angular';

@Component({
    selector: 'app-grid-sample',
    styleUrls: ['grid.sample.scss'],
    templateUrl: 'grid.sample.html',
    standalone: true,
    imports: [IGX_GRID_DIRECTIVES, AsyncPipe]
})

// Single import of only the <igx-grid> component.
import { IgxGridComponent } from 'igniteui-angular';

@Component({
    selector: 'app-grid-sample',
    styleUrls: ['grid.sample.scss'],
    templateUrl: 'grid.sample.html',
    standalone: true,
    imports: [IgxGridComponent, AsyncPipe]
})

or still

// `NgModule` import of the `IgxGridModule` module, which is equivalent to IGX_GRID_DIRECTIVES in terms of exported components and directives.
import { IgxGridModule } from 'igniteui-angular';

@Component({
    selector: 'app-grid-sample',
    styleUrls: ['grid.sample.scss'],
    templateUrl: 'grid.sample.html',
    standalone: true,
    imports: [IgxGridModule, AsyncPipe]
})

IgxChip
- Behavioral Change The igxChip styles have been revisited and the select container animation has been removed when selecting/deselecting a chip.
- Behavioral Change The remove button behavior have been revisited, now when the chip is in disabled state the remove button is hidden.
IgxGrid, IgxHierarchicalGrid:
- Breaking Change The IgxHeaderExpandIndicatorDirective and IgxHeaderCollapseIndicatorDirective directives, as well as the headerExpandIndicatorTemplate and headerCollapseIndicatorTemplate properties have been renamed to IgxHeaderExpandedIndicatorDirective, IgxHeaderCollapsedIndicatorDirective, headerExpandedIndicatorTemplate and headerCollapsedIndicatorTemplate respectively to properly reflect their purpose. Automatic migrations are available and will be applied on ng update.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid

Breaking Changes: The following grid properties, deprecated since version 12.1.0 are now removed:
- evenRowCSS;
- oddRowCSS;
- page;
- paging;
- perPage;
- totalPages;
- isFirstPage;
- isLastPage;
Also the following deprecated grid events are removed.
- pageChange;
- perPageChange;
- pagingDone;
Deprecated methods removed from the grid API are:
- nextPage;
- previousPage;
- paginate;
- getCellByColumnVisibleIndex;

New Features

IgxChip
- New input variant which can take any of the following values: 'primary', 'info', 'success', 'warning', 'danger'
IgxExpansionPanel:
- IgxExpansionPanelTitleDirective and IgxExpansionPanelDescriptionDirective show tooltip of the provided text content.
IgxDateRangePicker
- Added showWeekNumbers input that toggles whether or not the number of a week will be visible next to it
IgxGrid, IgxHierarchicalGrid:
- totalItemCount can now also be bound as Input in remote virtualization scenarios.
- rowExpandedIndicatorTemplate, rowCollapsedIndicatorTemplate, headerExpandedIndicatorTemplate, headerCollapsedIndicatorTemplate can now also be bound as Input to provide templates for the row and header expand/collapse indicators respectively. This is in addition to the existing equivalent template directives to allow reuse.
IgxPivotGrid
- Added pivotConfigurationChanged event triggered any time any of pivotConfiguration properties is changed via the UI.
ISortingExpression now accepts an optional generic type parameter for type narrowing of the fieldName property to keys of the data item, e.g. ISortingExpression<MyDataItem>
Util
- Added new CachedDataCloneStrategy that allows for cloning object with circular references.
IgxForOf
- Add support for as syntax in template to get bound data

15.1.0

New Features

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid:
- GroupMemberCountSortingStrategy is added, which can be used to sort the grid by number of items in each group in ASC or DESC order, if grouping is applied.
- A new argument primaryKey has been introduced to IRowDataEventArgs Interface and part of the event arguments that are emitted by the rowAdded and rowDeleted events. When the grid has a primary key attribute added, then the emitted primaryKey event argument represents the row ID, otherwise it defaults to undefined.
- Added the autoGenerateExclude property that accepts an array of strings for property names that are to be excluded from the generated column collection
IgxColumnComponent
- Added currRec and groupRec parameters to the groupingComparer function that give access to the all properties of the compared records.
IgxOverlayService
- A new event contentAppending is introduced - the event is emitted before the content is appended to the overlay. The event is emitted with OverlayEventArgs arguments and is not cancellable.

IgxCard

Buttons and icons slotted in the igx-card-actions can now be explicitly arranged to the start/end of the layout. To position components on either side users can take advantage of the newly added directives: igxStart - aligns items to the start and igxEnd - aligns items on the end of the card actions area.
The reverse property has been deprecated and will be removed in a future version.
Code example:

<igx-card>
    <igx-card-header>
        <h3>Title</h3>
    </igx-card-header>
    <igx-card-content>
        Card Content
    </igx-card-content>

    <!-- Rearrange items using igxStart and igxEnd directives -->
    <igx-card-actions>
        <igx-icon igxStart>drag_indicator</igx-icon>
        <button igxButton="icon" igxStart>

        </button>
        <button igxButton igxEnd>Button</button>
    </igx-card-actions>
</igx-card>

IgxButtonGroup:
- The selected and deselected events are now cancellable.

General

IgxPivotGrid
- The IgxPivotDateDimension properties inBaseDimension and inOption have been deprecated and renamed to baseDimension and options respectively.
IgxGrid
- Breaking Change The onGroupingDone output has been renamed to groupingDone to not violate the no on-prefixed outputs convention. Automatic migrations are available and will be applied on ng update.
- Column formatters are now applied to values shown group rows when using the default template. For custom formatters, the formatter function is called with the data from the first row in the group.
DisplayDensity
- Breaking Change The onDensityChanged output has been renamed to densityChanged to not violate the no on-prefixed outputs convention. All components exposing this event are affected. Automatic migrations are available and will be applied on ng update.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Breaking Change - rowSelectionChanging event arguments are changed. Now the oldSelection, newSelection, added and removed collections no longer consist of the row keys of the selected elements when the grid has set a primaryKey, but now in any case the row data is emitted. When the grid is working with remote data and a primary key has been set- for the selected rows that are not currently part of the grid view, will be emitted a partial row data object.
- Behavioral Change - When selected row is deleted from the grid component rowSelectionChanging event will no longer be emitted.
IgxCarousel
- Breaking Change The onSlideChanged, onSlideAdded, onSlideRemoved, onCarouselPaused and onCarouselPlaying outputs have been renamed to slideChanged, slideAdded, slideRemoved, carouselPaused and carouselPlaying to not violate the no on-prefixed outputs convention. Automatic migrations are available and will be applied on ng update.
IgxRadio, IgxRadioGroup, IgxCheckbox, IgxSwitch
- Added component validation along with styles for invalid state
igxMask directive
- Added the capability to escape mask pattern literals.
IgxBadge
- Added shape property that controls the shape of the badge and can be either square or rounded. The default shape of the badge is rounded.
IgxAvatar
- Breaking Change The roundShape property has been deprecated and will be removed in a future version. Users can control the shape of the avatar by the newly added shape attribute that can be square, rounded or circle. The default shape of the avatar is square.
IgxOverlayService
- attach method overload accepting ComponentFactoryResolver (trough NgModuleRef-like object) is now deprecated in line with API deprecated in Angular 13. New overload is added accepting ViewComponentRef that should be used instead.
Breaking Changes - $label-floated-background and $label-floated-disabled-background properties of IgxInputGroupComponent theme has been removed.
IgxInputGroupComponent The input group has been refactored so that the floating label for the input of type="border" does not require a background to match the surface background under the input field. Also, suffixes and prefixes are refactored to take the full height of the input which makes it easy to add background to them.
Breaking Changes - $size property of scrollbar-theme theme has been renamed to $scrollbar-size.
IgxSimpleCombo
- The IgxSimpleCombo will not open its drop-down on clear.

15.0.1

IgxGrid
- Added new auto-sizing API recalculateAutoSizes that recalculates widths of columns that have size set to auto. Can be used in scenarios where you want to auto-size the columns again post initialization.
- Clicking with the Left Mouse key while holding Ctrl on selected cell will deselect the cell.
igxPivotGrid
- Adding aggregatorName for pivot value configuration as an alternative to setting aggregator function. If both are set aggregatorName takes precedent. If none are set an error is thrown.
IgxSimpleCombo
- Behavioral Change
- When the user clicks on the combo's input, the dropdown opens up.
- Keyboard navigation ArrowUp - when the combo is opened ArrowUp will close the dropdown if the search input is focused. If the active item is the first one in the list, the focus will be moved back to the search input while also selecting all of the text in the input. Otherwise ArrowUp will move to the previous list item.

15.0.0

New Features

igxGrid - exposing new Input properties:
- Parameters in grid templates now have types for their context. This can also cause issues if the app is in strict template mode and uses the wrong type. References to the template that may require conversion:
  - - IgxColumnComponent - ColumnType (for example the column parameter in igxFilterCellTemplate)
  - - IgxGridCell - CellType (for example the cell parameter in igxCell template)
- A new groupRecord parameter has been exposed in operate method, that is an IGroupByRecord object describing the grouped row in case grouping is applied.
- excelStyleHeaderIconTemplate - Gets/Sets the excel style header icon.
- groupRowTemplate - Gets/Sets the template reference for the group row.
- headSelectorTemplate - Gets/Sets the header row selector template.
- rowSelectorTemplate - Gets/Sets the custom template used for row selectors.
- groupByRowSelectorTemplate - Gets/Sets the custom template used for the group row selectors.
- sortHeaderIconTemplate - Gets/Sets a custom template that should be used when rendering a header sorting indicator when columns are not sorted.
- sortAscendingHeaderIconTemplate - Gets/Sets a custom template that should be used when rendering a header sorting indicator when columns are sorted in asc order.
- sortDescendingHeaderIconTemplate - Gets/Sets a custom template that should be used when rendering a header sorting indicator when columns are sorted in desc order.
- rowEditActionsTemplate - Gets/Sets the row edit actions template.
- rowAddTextTemplate - Gets/Sets the row add text template.
- rowEditTextTemplate - Gets/Sets the row edit text template.
- dragGhostCustomTemplate - Gets/Sets the custom template used for row drag.
- dragIndicatorIconTemplate - Gets/Sets the custom template used for row drag indicator.
- detailTemplate - Gets/Sets the master-detail template.
IgxGridToolbar
- Breaking Change - The IgxGridToolbarTitleDirective and IgxGridToolbarActionsDirective have been converted to components, keeping only the element selector. For apps using the preferred element markup of <igx-grid-toolbar-title> and <igx-grid-toolbar-actions> there should be no functional change. Apps using the igxGridToolbarTitle and igxGridToolbarActions directives on other elements will need to convert those to the mentioned elements instead.
- Behavioral Change - When adding new row in grid with enabled batch editing, rowChangesCount displays the number of the defined columns.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Behavioral Change - When editing a row, rowChangesCount and hiddenColumnsCountwould be displayed.
- Behavioral Change - The Grid Paginator component is no longer hidden when there's no data and/or all columns are hidden.
IgxExcelExporterService
- Added support for exporting grid summaries.
- Columns of type currency will be formatted as currency in Excel based on grid's locale. Locale currency different than USD, EUR, GBP, CNY or JPY will result in exporting the column as number instead.
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid
- Adding Image column data type
IgxCalendar

Added support for shift key + mouse click interactions.
- multi mode - select/deselect all dates between the last selected/deselected and the one clicked while holding Shift.
- range mode - extend/shorten the range from the last selected date to the one clicked while holding Shift.
IgxFilterOptions
- Added support for multiple keys.

Theme Changes

Breaking Changes - The palette function no longer provides info, success, warn and error colors. Therefore you have to pass custom values for them if you need to use these colors. You can also use the values for info, success, warn and error colors from our predefined color palettes.

Code example:

// Mandatory colors
$primary-color: #2a38b7;
$secondary-color: #f96a88;
$surface-color: #e1ebe4;
// Additional colors
$error-color: color($light-fluent-palette, 'error');
$warn-color: color($light-fluent-palette, 'warn');
$info-color: color($light-fluent-palette, 'info');
$success-color: color($light-fluent-palette, 'success');

// Creating custom palette
$my-color-palette: palette(
    $primary: $primary-color,
    $secondary: $secondary-color,
    $surface: $surface-color,
    $error: $error-color,
    $warn: $warn-color,
    $info: $info-color,
    $success: $success-color
);

14.2.0

New Features

The filtering logic inside the grid's Advanced Filtering is now extracted as a separate IgxQueryBuilder component. The Query Builder allows you to build complex queries by specifying AND/OR operators, conditions and values using the UI. It outputs an object describing the structure of the query. Use the locale property to modify the locale settings. The default value is resolved to the global Angular application locale. The resourceStrings allows changing the displayed strings.
- Code example below:
```
<igx-query-builder [fields]="fields">
    
    <igx-query-builder-header [title]="'Custom title'"
        [showLegend]="false">
    </igx-query-builder-header>
</igx-query-builder>
```
- For more information, check out the README, specification and official documentation.
IgxExcelExporterService
- Added support for exporting igxPivotGrid.

General

Breaking Changes - The Excel exporter service exportEnded event has its xlsx argument type changed as igniteui-angular no longer depends on JSZip. Instead of providing a JSZip instance it is now an object describing the structure of the Excel file with property names corresponding to folders or files, folders being objects themselves that can be traversed down, while files have their contents as Uint8Array. The same structure is used to package as a zip file by fflate's API.
IgxDropDown
- The aria-label attribute of the IgxDropDownItemBase can now be se to a custom value for its descendants (of which IgxDropDownItem) by the ariaLabel property.

14.1.0

New Features

IgxCombo and IgxSimpleComboComponent
- filterFunction input is added. The new property allows changing of the way filtering is done in the combos. By default filtering is made over the values in combo's data when it is a collection of primitive values, or over the values as defined in displayKey of the combo. If custom filtering function is provided filtering will be done as specified in the provided function.
- filteringOptions are extended and now contains filterable and filteringKey properties. Setting filterable determines whether combo will be filterable. By default filtering is done over the data value when they are primitive, or over the field of the values equal to displayKey. filteringKey allows to filter data by any data related key.
igxPivotGrid
- Add option to template the pivot value chip content:
```
<ng-template igxPivotValueChip let-value>
        {{ value.member }}
</ng-template>
```
- Add support for usage with igxGridState to persist state of the pivotConfiguration with an additional pivotConfiguration option:
```
 <igx-pivot-grid
        #grid1
        [igxGridState]="options" ...
```
```
    public options : IGridStateOptions = {
    pivotConfiguration: true
};
```
One known issue of the igxGridState directive is that it cannot store functions as the state is stored as string. As a result any custom functions set to memberFunction, aggregator, formatter, styles etc. will not be stored. Restoring any of these can be achieved with code on application level. Hence we have also exposed 2 new events: - dimensionInit - emits when a dimension from the configuration is being initialized. - valueInit - emits when a value from the configuration is being initialized. Which can be used to set back any custom functions you have in the configuration. The default aggregator function, like the ones from IgxPivotNumericAggregate, IgxPivotDateAggregate etc., will be restored out of the box. However if you have any custom aggregators (or other custom functions) they need to be set back in the valueInitevent, for example:
```
    public onValueInit(value: IPivotValue) {
    if (value.member === 'AmountOfSale') {
        value.aggregate.aggregator = IgxTotalSaleAggregate.totalSale;
    }
}
```
Same applies to any custom functions on the dimension, like memberFunction. If it is a custom function you can set it back on the dimensionInit event:
```
 public onDimensionInit(dim: IPivotDimension) {
    if (dim.memberName === 'AllCities') {
        dim.memberFunction = () => 'All';
    }
}
```
- igxGridState: Exposed a stateParsed event to the state directive that can be used to additionally modify the grid state before it gets applied.
```
this.state.stateParsed.subscribe(parsedState => {
        parsedState.sorting.forEach(x => x.strategy = NoopSortingStrategy.instance());
    });
```
igxGrid
- Added built-in validation mechanism for Grid Editing. Extends the Angular Form validation functionality You can configure it in 2 ways:
  1. Via template-driven configuration on the igx-column of the grid:
```
<igx-column required minlength="4" ...>
```
  2. Via reactive forms using the FormGroup exposed via the formGroupCreated event of the grid:
```
<igx-grid (formGroupCreated)='formCreateHandler($event)' ...>
```
```
public formCreateHandler(formGr: FormGroup) {
    // add a validator
    const prodName = formGr.get('UserName');
    prodName.addValidators(forbiddenNameValidator(/bob/i))
}
```
  Edited cells will enter an invalid state when validation fails and will show an error icon and message. Cell will remain invalid until the value is edited to a valid value or the related state in the validation service is cleared.
  
  You can refer to the documentation for more details: https://www.infragistics.com/products/ignite-ui-angular/angular/components/grid/validation
- Added ability to auto-size columns to the size of their cells and header content on initialization by setting width auto:
```
<column width='auto' ...>
```
- Added support for restoring filtering expressions with custom filtering operands for the IgxGridStateDirective.
Added the IgcFormControl directive that, when imported with its IgcFormsModule, is designed to seamlessly attach to form components from the Ignite UI for WebComponents package and allows using them in Angular templates and reactive forms with support for ngModel and formControlName directives. Currently the only Web Component with support through the directive is igc-rating.

General

Breaking Changes - filterable property of IgxComboComponent is now deprecated and will be removed in future version. Use filteringOptions.filterable instead.

Theme Changes

Breaking Changes - $disable-shadow property of IgxTabsComponent theme has been removed.

14.0.0

Added additional theme properties for the IgxCalendar so that it's easier to style the :hover and :focus states inside the selected date or range of dates.
IgxDatePicker and IgxDateRangePicker now expose a weekStart input property like the IgxCalendar
IgxCombo and IgxSimpleComboComponent
- The combobox role, aria-haspopup, aria-expanded, aria-controls and aria-labelledby attributes have been moved from combo wrapper to the combo input. Additionally the IgxSimpleComboComponent input is marked with aria-readonly="false" and aria-autocomplete="list" attributes. The aria-labelled attribute is applied to the combo dropdown as well and can be set by the ariaLabelledBy property, the combo label or placeholder. The serach input within the combo dropdown is now marked as role="searchbox", aria-label="search" and aria-autocomplete="list". The dropdown item container has aria-activedescendant attribute to identify the currently active element of the item list. The IgxCombo container is also marked as aria-multiselectable="true". The dropdown header items role has been changed to group.
IgxDropDown
- The label attribute has been changed to aria-labelledby and can be set by a latterly added input property labelledBy.

New Features

IgxCombo and IgxSimpleComboComponent
- filterFunction input is added. The new property allows changing of the way filtering is done in the combos. By default filtering is made over the values in combo's data when it is a collection of primitive values, or over the values as defined in displayKey of the combo. If custom filtering function is provided filtering will be done as specified in the provided function.

General

Updating dependency to Angular 14
Migrations

- weekStart property of IgxCalendar, IgxDatePicker, IgxDateRangePicker and IgxGrid will default to the default first day for the current component locale, if not set.

13.2.0

General

IgxPivotGrid
- Breaking Change - Changing the IPivotValue's formatter and styles functions optional parameters, example:
```
    formatter?: (value: any, rowData?: IPivotGridRecord, columnData?: IPivotGridColumn) => any;
```
First optional parameter rowData is now of type IPivotGridRecord and contains more contextual information on the dimension and aggregation values. Previously it contained just the aggregation data object. Old usage can be updated as follows, from:
```
    formatter: (value: any, rowData: any) => rowData['someField'];
```
to:
```
    formatter: (value: any, rowData: IPivotGridRecord) => rowData.aggregationValues.get('someField');
```
Also an additional optional columnData parameter can be added, which contains information on the column dimensions.
IgxExpansionPanel
- Changed the expansion panel layout, adding padding to the header and content elements.

- new sortingOption property has been introduced on grid level; This property allows you to set either single or multiple sorting mode; When single mode is enabled you can sort one column at a time; The default value of the property is multiple;
- Behavioral Change - sorting and grouping expressions are now working separately; If grouping/sorting expressions are in a conflict, grouping expressions take precedence. You can read more about that in our official documentation.
IgxSlider
- support for double value binding in slider of type RANGE through newly exposed lowerValue and upperValue
IgxDrag
- Behavioral Change - support for window scroll when dragging element to its edges
- new scrollContainer property that can specify specific element that should be scrolled instead of window for custom solutions.

13.1.0

New Features

Added new CSS property --igx-icon-size to allow changing the icon when its original size is modified by other components.

    // will have effect only on icons that are children of .igx-button
    .igx-button {
        --igx-icon-size: 10px;
    }

Added IgxPivotGrid component(Preview)
- The igxPivotGrid is a data presentation control for displaying data in a pivot table. It enables users to perform complex analysis on the supplied data. Main purpose is to transform and display a flat array of data into a complex grouped structure with aggregated values based on the main 3 dimensions: rows, columns and values, which the user may specify depending on his/her business needs. The whole pivot grid configuration is set through IPivotConfiguration interface.
```
<igx-pivot-grid [data]="origData" [pivotConfiguration]="pivotConfigHierarchy">
</igx-pivot-grid>
```
- For more information, check out the README, specification and official documentation.
IgxTreeGrid
- Added support for tree filter items in the Excel Style filtering UI. Use the TreeGridFilteringStrategy constructor to specify which columns should display tree filter items.
igxTooltipTarget directive now allows specifying a plain text tooltip without adding an additional DOM element decorated with the igxTooltip directive. This is achieved via the newly introduced tooltip string input.
```
<button igxTooltipTarget [tooltip]="'Infragistics Inc. HQ'">
   info
</button>
```
IgxTabs have full right-to-left (RTL) support.
IgxExcelExporterService
- Added support for exporting the grids' headers by default when the data is empty. This behavior can be controlled by the alwaysExportHeaders option of the IgxExcelExporterOptions object.
Theming
- Added --igx-radius-factor property to allow for easier update of all components' roundness. Its value can be any decimal fraction between 0 and 1. By default the value is set to 1.
- Added --igx-elevation-factor property to allow for easier update of all components' shadows at runtime.

General

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Breaking Change - movable property of IgxColumnComponent is now deprecated and will be removed in future version. Instead, use the newly exposed moving property on grid-level:
```
<igx-grid [data]="data" [moving]="true">
    <igx-column field="Name"></igx-column>
    <igx-column field="Age"></igx-column>
</igx-grid>
```
- Breaking Change - getFilterItems method is added to the IFilteringStrategy interface. Using the new method you could retrieve either list or tree filter items to be displayed for a column in the Excel Style filtering UI. If you have your own implementation of the IFilteringStrategy interface, you will need to implement the new method. Otherwise, you could derive from the BaseFilteringStrategy class or any of its sub-classes, which already implement the new method.
- Exposed dataChanging and dataChanged events for the three grids that are re-emits of the corresponding IgxForOf events. These indicate the beginning and end of the input change triggering the actual data re-rendering which happens each time the data view changes. This happens after changes in either the data the grid is bound or the state affecting the operations which alter this data (e.g. sorting, filtering, group-by).
- Scrolling with the mouse wheel over cells with templates that include scrollable containers now correctly scroll these inner containers before the grid body scrolls.
IgxToast
- Breaking Changes - The toast deprecated position property have been removed. We suggest using positionSettings property instead.

```
<igx-column ... [hasSummary]="true">
    <ng-template igxSummary let-summaryResult>
        <span> My custom summary template</span>
        <span>{{ summaryResult[0].label }} - {{ summaryResult[0].summaryResult }}</span>
    </ng-template>
</igx-column>
```
- Please, refer to the Summaries topic for more information.

    <igx-step *ngFor="let step of stepsData" >
        ...
    </igx-step>
</igx-stepper>
```
- For more information, check out the README, specification and official documentation.

Added IgxFocusTrap directive, which traps the Tab key focus within an element.

<div #wrapper [igxFocusTrap]="true" tabindex="0">
    <input type="text" placeholder="Enter Username" name="uname">

import { slideInBottom, slideOutTop } from 'igniteui-angular';

@ViewChild('alert', { static: true }) public alert: IgxDialogComponent;
public newPositionSettings: PositionSettings = {
    openAnimation: useAnimation(slideInBottom, { params: { fromPosition: 'translateY(100%)' } }),
    closeAnimation: useAnimation(slideOutTop, { params: { toPosition: 'translateY(-100%)'} })
};

igxGrid, igxHierarchicalGrid, igxTreeGrid
- Breaking Change - The following deprecated inputs have been removed
  - Inputs showToolbar, toolbarTitle, columnHiding, columnHidingTitle, hiddenColumnsText, columnPinning, columnPinningTitle, pinnedColumnsText. Use IgxGridToolbarComponent, IgxGridToolbarHidingComponent, IgxGridToolbarPinningComponent instead.
- Breaking Change - The rowSelected event is renamed to rowSelectionChanging to better reflect its function.
- Breaking Change - The columnSelected event is renamed to columnSelectionChanging to better reflect its function.
- Breaking Change - columnsCollection is removed. Use columns instead. If at certain ocasions columns return empty array, query the columns using ViewChildren and access those in ngAfterViewInit:

IgxCarousel
- Breaking Changes - The carousel animation type CarouselAnimationType is renamed to HorizontalAnimationType.
Theming
- Breaking Change - Changed CSS palette variables from HEX values to a list of H, S, L comma-separated values, which requires the use of the CSS hsl function when accessing these values directly.
```
.bozo {
    background: hsl(var(--igx-surface-500));
}
```

12.2.3

General

Breaking Change - IgxPercentSummaryOperand and IgxCurrencySummaryOperand have been removed and IgxNumberSummaryOperand should be used instead. If you have used the percent or currency summary operands to extend a custom summary operand from them, then change the custom operand to extend from the number summary operand.
IgxToastComponent
- Deprecated - The position input property has been deprecated. Use positionSettings input instead.

12.2.1

New Features

igxGrid, igxHierarchicalGrid, igxTreeGrid
- new rowPinned event is emitted after a row is pinned/unpinned and grid has already refreshed its state to represent the pinned/unpinned rows in the DOM.

12.2.0

New Features

igxGrid, igxHierarchicalGrid, igxTreeGrid
- Added capability to restore the state of multi column headers with IgxGridStateDirective.
- Introduced new 'rowStyles' and 'rowClasses' grid properties which allows to define a custom styling on each grid row
- Introduced two new cancellable outputs related to CRUD - rowDelete and rowAdd. Both use an IGridEditEventArgs object as an event argument.
```
<igx-grid #grid [data]="localData" (rowAdd)="rowAdd($event)" (rowDelete)="rowDelete($event)" [autoGenerate]="true"></igx-grid>
```
- Added two public methods that spawn the add row UI for an arbitrary record in the current data view. One that accepts a rowID to use as the row the UI spawns under and the other accepting an index that has a distinct implementation for IgxTreeGrid. Please, refer to the official documentation for more information: Grid Row Adding and Tree Grid Row Adding.
  
  Note: That the new record is still added at the end of the data view, after the end-user submits it.
```
this.grid.beginAddRowById('ALFKI');             // spawns the add row UI under the row with PK 'ALFKI'
this.grid.beginAddRowById(null);                // spawns the add row UI as the first record
this.grid.beginAddRowByIndex(10);               // spawns the add row UI at index 10
this.grid.beginAddRowByIndex(0);                // spawns the add row UI as the first record

General

igxGrid, igxHierarchicalGrid, igxTreeGrid
- 'oddRowCSS' and 'evenRowCSS' properties has been deprecated
- The column formatter callback signature now accepts the row data as an additional argument:
```
formatter(value: any, rowData?: any)
```
  The rowData argument may be undefined in remote scenarios/applying the callback on filtering labels so make sure to check its availability.
IgxForOf - now takes margins into account when calculating the space that each element takes.

Note: If your virtualized items contain margins, please calculate them into the itemSize value for the best possible initial virtualized state.
IgxExcelExporterService
- Added support for freezing column headers in Excel. By default, the column headers would not be frozen but this behavior can be controlled by the freezeHeaders option of the IgxExcelExporterOptions object.

12.1.0

New Features

Added IgxAccordion component
- A collection of vertically collapsible igx-expansion-panels that provide users with data and the ability to navigate through it in a compact manner. The control is not data bound and takes a declarative approach, giving users more control over what is being rendered.
- Exposed API to control the expansion state, easy-to-use keyboard navigation, option for nested accordions.
- Code example below:
```
<igx-accordion>
    <igx-expansion-panel *ngFor="let panel of panels">
       ...
    </igx-expansion-panel>
</igx-accordion>
```
- For more information, check out the README, specification and official documentation

igxGrid

New additionalTemplateContext column input:

<igx-column [additionalTemplateContext]="contextObject">
  <ng-template igxCell let-cell="cell" let-props="additionalTemplateContext">
     {{ props }}
  </ng-template>
</igx-column>

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Added batchEditing - an Input property for controlling what type of transaction service is provided for the grid. Setting <igx-grid [batchEditing]="true"> is the same as providing [{ provide: IgxGridTransaction, useClass: IgxTransactionService }].
- Deprecation - Providing a transaction service for the grid via providers: [IgxTransactionService] is now deprecated and will be removed in a future patch. Instead, use the new batchEditing property to control the grid's Transactions.
```
<igx-grid #grid [data]="data" [batchEditing]="true">
    ...
</igx-grid>
<button igxButton (click)="grid.transactions.undo">Undo</button>
```
- Breaking changes
  - IgxGridCellComponent, IgxTreeGridCellComponent, IgxHierarchicalGridCellComponent are no longer exposed in the public API. Instead, a new class IgxGridCell replaces all of these. It is a facade class which exposes only the public API of the above mentioned. Automatic migration will change these imports with CellType, which is the interface implemented by IgxGridCell
- Behavioral changes
- getCellByKey, getCellByColumn, getCellByColumnVisibleIndex, row.cells, column.cells, grid.selectedCells now return an IgxGridCell the CellType interface.
- cell in IGridCellEventArgs is now CellType. IGridCellEventArgs are emitted in cellClick, selected, contextMenu and doubleClick events.
- let-cell property in cell template is now CellType.
- getCellByColumnVisibleIndex is now deprecated and will be removed in next major version. Use getCellByKey, getCellByColumn instead.
Transactions
- Added IgxFlatTransactionFactory - the singleton service instantiates a new TransactionService<Transaction, State> given a transaction type.
- Added IgxHierarchicalTransactionFactory - the singleton service instantiates a new HierarchicalTransactionService<HierarchicalTransaction, HierarchicalState> given a transaction type.

Toolbar Actions

Exposed a new input property overlaySettings for all column actions (hiding | pinning | advanced filtering | exporter). Example below:

<igx-grid-toolbar-actions>
    <igx-grid-toolbar-pinning [overlaySettings]="overlaySettingsGlobal"></igx-grid-toolbar-pinning>
    <igx-grid-toolbar-hiding [overlaySettings]="overlaySettingsAuto"></igx-grid-toolbar-hiding>
</igx-grid-toolbar-actions>

IgxPaginatorComponent

Added paging and pagingDone events; paging event is cancellable and is emitted before pagination is performed, pagingDone event gives you information about the previous and the current page number and is not cancellable; Also IgxPageSizeSelectorComponent and IgxPageNavigationComponent are introduced and now the paginator components allows you to define a custom content, as it is shown in the example below:

<igx-paginator #paginator>
    <igx-paginator-content>
        <igx-page-size></igx-page-size>
        <button [disabled]="paginator.isFirstPage" (click)="paginator.previousPage()">PREV</button>
        <span>Page {{paginator.page}} of {{paginator.totalPages}}</span>
        <button [disabled]="paginator.isLastPage" (click)="paginator.nextPage()">NEXT</button>
    </igx-paginator-content>
</igx-paginator>

Exporters's columnExporting event now supports changing the index of the column in the exported file.

    this.excelExporterService.columnExporting.subscribe((col) => {
        if (col.field === 'Index') {
            col.columnIndex = 0;
        }
    });

IgxExcelExporterService
- Added support for exporting the grids' multi-column headers to Excel. By default, the multi-column headers would be exported but this behavior can be controlled by the ignoreMultiColumnHeaders option off the IgxExcelExporterOptions object.
IgxDateTimeEditor, IgxMask, IgxDatePicker, IgxTimePicker, IgxDateRangePicker
- Added IME input support. When typing in an Asian language input, the control will display input method compositions and candidate lists directly in the control’s editing area, and immediately re-flow surrounding text as the composition ends.

New Features

Added IgxTree component

Allows users to render hierarchical data in an easy-to-navigate way. The control is not data bound and takes a declarative approach, giving users more control over what is being rendered.
Features API for handling selection (bi-state and cascading), node activation, node expansion state.
Features extensive and easy-to-use keyboard navigation, fully compliant with W3 standards.
Code example for a tree contructured from a hierarchical data set:

    <igx-tree>
        <igx-tree-node *ngFor="let node of data" [data]="node" [expanded]="isNodeExpanded(node)" [selected]="isNodeSelected(node)">
            {{ node.text }}
            <img [src]="node.image" alt="node.imageAlt" />
            <igx-tree-node *ngFor="let child of node.children" [data]="child" [expanded]="isNodeExpanded(child)" [selected]="isNodeSelected(child)">
                {{ child.text }}
                <igx-tree-node *ngFor="let leafChild of child.children" [data]="leafChild" [expanded]="isNodeExpanded(leafChild)" [selected]="isNodeSelected(leafChild)">
                    <a igxTreeNodeLink href="{{leafChild.location}}" target="_blank">{{ leafChild.text }}</a>
                </igx-tree-node>
            </igx-tree-node>
        </igx-tree-node>
    </igx-tree>

For more information, check out the README, specification and official documentation

IgxHierarchicalGrid
- Added support for exporting hierarchical data.
IgxForOf, IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Behavioral Change - Virtual containers now scroll smoothly when using the mouse wheel(s) to scroll them horizontally or vertically. This behavior more closely resembles the scrolling behavior of non-virtualized containers in most modern browsers.

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid

The IgxRowAddTextDirective allows to customize the text of the row adding overlay.

     <igx-grid [rowEditable]="true">
        <ng-template igxRowAddText>
            Adding Row
        </ng-template>
    </igx-grid>

A new summaryFormatter input property is exposed by the IgxColumnComponent, which is used to format the displayed summary values for the columns.

    public dateSummaryFormat(summary: IgxSummaryResult, summaryOperand: IgxSummaryOperand): string {
        const result = summary.summaryResult;
        if(summaryOperand instanceof IgxDateSummaryOperand && summary.key !== 'count'
            && result !== null && result !== undefined) {
            const pipe = new DatePipe('en-US');
            return pipe.transform(result,'MMM YYYY');
        }
        return result;
    }

    <igx-column field="OrderDate" header="Order Date" [sortable]="true" [disableHiding]="true" [dataType]="'date'" [hasSummary]="true"
        [summaryFormatter]="dateSummaryFormat">
    </igx-column>

Two new column types are introduced dateTime and time. In order to operate with them is necessary to set the column property dataType to 'dateTime' or 'time'.

<igx-column field="OrderDate" header="Order Date"  [dataType]="'dateTime'" >
</igx-column>
<igx-column field="ClosingTime" header="Closing time"  [dataType]="'time'" >
</igx-column>

Behavioral Change - Column Autosize feature now does not handle templated headers where the first level children are sized based on parent like default div and etc. Autosizing for such headers will not result in change.
Behavioral Change - Calling autosize through the IgxColumnComponent API now takes into consideration the minWidth and maxWidth of the column.
A new IgxColumnComponent input property is exposed called autosizeHeader, which if false, allows the autosizing to ignore the header cell and autosize only based on content cells.

IgxTabs
- The tabAlignment property of the IgxTabs component replaces the type property and enables you to set the tab alignment to start, center, end and justify.
- The igx-tab-header supports igx-prefix and igx-suffix directives in its ng-content.
IgxBottomNav
- The IgxBottomNav component exposes disableAnimations property which determines whether the contents should animate when switching the selected item. The property is set to true by default which means that the animations are disabled.
IgxOverlayService
- detach and detachAll methods are added to IgxOverlayService. Calling detach will remove all the elements generated for the related overlay, as well as clean up all related resources. Calling detachAll will remove all elements generated by any call to IgxOverlay attach, and will clean up all related resources. Note: calling hide or hideAll will not clean generated by the service elements and will not clean up related resources.

IgxCombo

Any changes to IComboItemAdditionEvent.addedItem will be reflected in the item added to the data.
IgxComboComponent.onAddition is now cancelable. You can prevent the item from being added by setting the event args cancel property to true.

public handleComboItemAddition(event: IComboItemAdditionEvent): void {
    if (event.addedItem[this.combo.valueKey] === 'ForbiddenValue') {
        event.cancel = true;
    } else if (event.addedItem[this.combo.valueKey] === 'Change Me') {
        const index = this.iter++;
        event.addedItem = {
            [this.combo.valueKey]: `customId${index}`,
            [this.combo.displayKey]: `New item ${index}`;
        }
    }
}

IgxDateTimeEditor
- value accepts ISO 8601 string format.
- spinDelta input property which allows a user to provide different delta values that will be used for spinning. All parts default to 1.
- increment and decrement methods now accept an optional delta parameter which targets the currently spun date portion. It takes precedence over the values set in spinDelta.

IgxDatePicker

value accepts ISO 8601 string format.

The actions template now exposes the Calendar component as implicit context:

<igx-date-picker>
  <ng-template igxPickerActions let-calendar>
      <button igxButton="flat" (click)="calendar.viewDate = today">Today</button>
  </ng-template>
</igx-date-picker>

IgxTimePicker

value accepts ISO 8601 string format.

The igxPickerActions directive can now be used to provide custom buttons to the picker's pop-up:

<igx-time-picker #timePicker>
  <ng-template igxPickerActions>
      <button igxButton="flat" (click)="timePicker.close()">Close</button>
  </ng-template>
</igx-time-picker>

IgxDateRangePicker

value start and end accept ISO 8601 string format.

The igxPickerActions directive can now be used to template the pickers Done button:

<igx-date-range-picker #rangePicker>
  <ng-template igxPickerActions>
      <button igxButton="flat" (click)="rangePicker.close()">Close</button>
  </ng-template>
</igx-date-range-picker>

Themes:

Breaking Changes:
- IgxButton theme has been simplified. The number of theme params (igx-button-theme) has been reduced significantly and no longer includes prefixed parameters (flat-*, raised-*, etc.). See the migration guide to update existing button themes. Updates performed with ng update will migrate existing button themes but some additional tweaking may be required to account for the abscense of prefixed params.
- The igx-typography mixin is no longer implicitly included with igx-core. To use our typography styles users have to include the mixin explicitly:
```
@include igx-core();
/// Example with Indigo Design theme:
@include igx-typography($font-family: $indigo-typeface, $type-scale: $indigo-type-scale);
```

</igx-tree-grid>
```
IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Support for currency type columns is added in the grid.

Breaking Changes Due to a breaking change in Angular 9 with Ivy, Hammer providers are no longer included by default. You can find more information at: https://github.com/angular/angular/blob/master/CHANGELOG.md#breaking-changes-9 . Because of this change the following components require HammerModule to be imported in the root module of the application in order for user interactions to work as expected:
- IgxSlider
The following components require HammerModule to be imported in the root module of the application so that their touch interactions work as expected:

    [rowDraggable]="true">
    <igx-column field="ProductName"></igx-column>
    <igx-column field="ProductID"></igx-column>
    <igx-column field="UnitsInStock"></igx-column>
    <ng-template let-data igxRowDragGhost>
        <div>
            Moving {{data.ProductName}}!
        </div>
    </ng-template>

- adding IgxSelectHeaderDirective and IgxSelectFooterDirective. These can be used to provide a custom header, respectively footer templates for the igxSelect drop-down list. If there are no templates marked with these directives - no default templates will be used so the drop-down list will not have header nor footer.

IgxCombo:

Added displayText property to the combo's onSelectionChange event args. The property contains the text that will be populated in the combo's text box after selection completes. This text can be overwritten in order to display a custom message, e.g. "3 items selected":

<igx-combo [data]="people" valueKey="id" displayKey="name" placeholder="Invite friends..." (onSelectionChange)="handleSelection($event)">

export class MyInvitationComponent {
    public people: { name: string; id: string }[] = [...];
    ...
    handleSelection(event: IComboSelectionChangingEventArgs) {
        const count = event.newSelection.length;

IgxCircularProgressBar:

added IgxProgressBarGradientDirective to allow providing custom circular progress SVG gradients. Providing a custom gradient via a template is as easy as writing:

<igx-circular-bar [value]="77">
    <ng-template igxProgressBarGradient let-id>
        <svg:linearGradient [id]="id" gradientTransform="rotate(90)">
            <stop offset="0%"   stop-color="#05a"/>
            <stop offset="100%" stop-color="#0a5"/>
        </svg:linearGradient>
    </ng-template>
</igx-circular-bar>

changed the igx-progress-circular-theme to accept a list of 2 colors for the $progress-circle-color argument, making it easier to modify the default gradient:

$theme: igx-progress-circular-theme(
    $progress-circle-color: red blue
);

@include igx-progress-circular($theme);

RTL support

IgxForOf
- IgxForTotalItemCount input is added for the cases when the data is from remote services. This will allow setting the count of the items through the template. And gives the opportunity for the developers to use AsyncPipe for this option:
```
<ng-template igxFor let-item [igxForOf]="data | async" [igxForTotalItemCount]="count | async"
    [igxForContainerSize]="'500px'" [igxForItemSize]="'50px'"></ng-template>
```

8.2.6

New Features

IgxSelectItem
- text input is added. By default, the Select component will display the selected item's element inner text. In cases with a more complex item template, where more than just text interpolation is used, set the text property to specify what to display in the select field when the item is selected.

8.2.4

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- The header text of the columns and the column groups now has the title attribute set to it in order to expose a native browser tooltip.

RTL Support

Most of the components in the framework now have full right-to-left (RTL) support via the newly included RTL themes.

For CSS-based projects add node_modules/igniteui-angular/styles/igniteui-angular-rtl.css to your angular.json styles collection.

For Sass-based projects pass $direction to the igx-core mixin in your root stylesheet.

Example:

// $direction defaults to ltr if it's omitted.
@include igx-core($direction: rtl);

Currently the following components have only partial RTL support:

Grid (igx-grid)
Slider (igx-slider)
Tabs (igx-tabs)
Circular Progress Indicator (igx-circular-bar)

We plan on adding support for the aforementioned components in the upcoming releases.

New Features

Columns now expose the cellStyles property which allows conditional styling of the column cells. Similar to cellClasses it accepts an object literal where the keys are style properties and the values are expressions for evaluation.

styles = {
    color: '#123456',
    'font-family': 'monospace'
    'font-weight': (_, __, value) => value.startsWith('!') : 'red' : 'inherit'
};

The callback signature for both cellStyles and cellClasses is now changed to

(rowData: any, columnKey: string, cellValue: any, rowIndex: number) => boolean

8.2.3

IgxTextHighlightDirective - The default highlight directive styles have been moved to a Sass theme - igx-highlight-theme; You can modify the resting and active background and text color styles of the directive by passing the respective properties to the Sass theme. You can still pass your own CSS classes to the highlight directive via the cssClass and activeCssClass inputs.
IgxChip
- Breaking Change The originalEvent property for the events onMoveStart, onMoveEnd, onClick and onSelection now provides the events, passed from the igxDrag directive. The passed original events are in other words the previous events that triggered the igxChip ones. They also have original events until a browser event is reached.
IgxGrid - Now you can access all grid data inside the custom column summary. Two additional optional parameters are introduced in the IgxSummaryOperand operate method.

class MySummary extends IgxNumberSummaryOperand {
    constructor() {
        super();
    }
    operate(columnData: any[], allGridData = [], fieldName?): IgxSummaryResult[] {
        const result = super.operate(allData.map(r => r[fieldName]));
        result.push({ key: 'test', label: 'Total Discounted', summaryResult: allData.filter((rec) => rec.Discontinued).length });
        return result;
    }
}

8.2.0

New theme

Ignite UI for angular now have a new theme that mimics Microsoft "Fluent" design system. Depending on your use case you can use one of the following mixins: igx-fluent-theme and igx-fluent-dark-theme

We also added two new palettes that go with the new theme, $fluent-word-palette and $fluent-excel-palette.

Next example shows how you can use the Fluent theme.

// Light version
.fluent-word-theme {
    @include igx-fluent-theme($fluent-word-palette);
}

// Dark version
.fluent-excel-dark-theme {
    @include igx-fluent-dark-theme($fluent-excel-palette);
}

Theme Changes

igx-badge-theme - Removed the $disable-shadow property to mitigate confusion when specifying $shadow explicitly.

For more information about the theming please read our documentation

New Features

The advanced filtering button is shown in the grid's toolbar when allowAdvancedFiltering and showToolbar properties are set to true. You could also open/close the advanced filtering dialog using the openAdvancedFilteringDialog and closeAdvancedFilteringDialog methods.
- uniqueColumnValuesStrategy input is added. This property provides a callback for loading unique column values on demand. If this property is provided, the unique values it generates will be used by the Excel Style Filtering (instead of using the unique values from the data that is bound to the grid).
- [filterStrategy] - input that allows you to override the default filtering strategy
- igxExcelStyleLoading directive is added, which can be used to provide a custom loading template for the Excel Style Filtering. If this property is not provided, a default loading template will be used instead.

- introduced functionality for templating row and header selectors - spec
```
<igx-grid [data]="data", [rowSelection]="'multiple'" primaryKey="ID">
    <igx-column field="Name"></igx-column>
    <igx-column field="Age"></igx-column>

    <ng-template igxHeadSelector let-headSelector>
        <igx-icon>done_all</igx-icon>
    </ng-template>
    <ng-template igxRowSelector let-rowContext>
        <igx-switch [checked]="rowContext.selected"></igx-switch>
    </ng-template>
</igx-grid>
```
IgxHierarchicalGrid
- Row Islands now emit child grid events with an additional argument - owner, which holds reference to the related child grid component instance.
IgxDrag
- Dragging without ghost. Now it is possible to drag the base element igxDrag is instanced on by setting the new input ghost to false.
- Ghost template. A custom ghost template reference can be provided on the new ghostTemplate input.
- Dragging using a single or multiple handles. New igxDragHandle directive is exposed to specify a handle by which an element can be interacted with instead of the whole element igxDrag is instanced on.
- Linking of drag and drop elements. This can be achieved by using the new provided dragChannel input, specifying each element to which channel it corresponds.
- Drag animation improvements. Three new methods have been exposed in place of the old animateToOrigin input in order to provide more flexibility when wanting to have transition animation to specific position when dropping. setLocation, transitionToOrigin and transitionTo are all methods that provide a various way to animate a transition to a specific location for the dragged element.
- New getters - location and originLocation to aid in applying transition animations.
- New outputs - dragMove, ghostCreate and ghostDestroy
IgxDrop
- Linking of drag and drop elements. This can be achieved by using the new provided dropChannel input, specifying each drop area to which channel it corresponds.

IgxCheckbox
- introduced a new readonly property that doesn't allow user interaction to change the state, but keeps the default active style. Intended for integration in complex controls that handle the interaction and control the checkbox instead through binding.
IgxOverlay
- introduced a new ContainerPositionStrategy. The new strategy positions the element inside the containing outlet based on the directions passed in trough PositionSettings.
IgxChip
- add onSelectionDone event that is triggered after all animations and transitions related to selection have ended.

IgxCombo

Combo selection is now consistent when valueKey is defined. When valueKey is specified, selection is based on the value keys of the items. For example:

<igx-combo [data]="myCustomData" valueKey="id" displayKey="text"></igx-combo>

export class MyCombo {
    ...
    public combo: IgxComboComponent;
    public myCustomData: { id: number, text: string } = [{ id: 0, name: "One" }, ...];
    ...
    ngOnInit() {
        // Selection is done only by valueKey property value
        this.combo.selectItems([0, 1]);
    }
}

7.2.0

igxCalendar
- igxCalendar has been refactored to provide the ability to instantiate each view as a separate component.
- Feature advanced keyboard navigation support has been added. Read up more information in the ReadMe
New component IgxMonthPicker:
- Provides the ability to pick a specific month. Read up more information in the ReadMe
New component IgxHierarchicalGrid:
- Provides the ability to represent and manipulate hierarchical data in which each level has a different schema. Each level is represented by a component derived from igx-grid and supports most of its functionality. Read up more information about the IgxHierarchicalGrid in the official documentation or the ReadMe

New component The igxSelect provides an input with dropdown list allowing selection of a single item.

<igx-select #select1 [placeholder]="'Pick One'">
    <label igxLabel>Sample Label</label>
    <igx-select-item *ngFor="let item of items" [value]="item.field">
        {{ item.field }}
    </igx-select-item>
</igx-select>

documentation or the ReadMe

New directive igxAutocomplete - new directive that provides a way to enhance a text input by showing a panel of suggested options, provided by the developer. More information about the IgxAutocomplete is available in the official documentation or the ReadMe.
```
<input igxInput type="text" [igxAutocomplete]="townsPanel" />
<igx-drop-down #townsPanel>
    <igx-drop-down-item *ngFor="let town of towns" [value]="town">
        {{town}}
    </igx-drop-down-item>
</igx-drop-down>
```
igxGrid now has isLoading input property. When enabled will show loading indicator, until the data is available. It can be best utilized for remote scenarios. Another input property loadingGridTemplate allows customizing the loading indicator.
```

<igx-grid [isLoading]="true" ...>
</igx-grid>
```
- Group By
  - The collapse/expand icons have new orientantion to display the action that will be performed when clicked. When an icon points up clicking on it would result in collapsing the related group row and when it points down clicking on it would expand the group row.
  - The collapse/expand all icons have also been updated to reflect the new group row icons better.
  - Group rows now can be expanded/collapsed using Alt + Arrow Up/Down to reflect the new icons.
- filterMode input added, which determines the filtering ui of the grid. The default value is quickFilter. Other possible value is excelStyle, which mimics the filtering in Excel with added functionality for column moving, sorting, hiding and pinning.
- IgxColumnComponent now has disablePinning property, which determines wether the column can be pinned from the toolbar and whether the column pin will be available in the excel style filter menu. The disableHiding input will be used to show/hide the column hiding functionality in the menu.
igxTreeGrid
- The collapse/expand icons have new orientantion to display the action that will be performed when clicked. When an icon points up clicking on it would result in collapsing the related tree grid level and when it points down clicking on it would expand the tree grid level.
- Expanding/collapsing tree levels can now be performed also by using Alt + Arrow Up/Down to reflect the new icons.
IgxColumnComponent
- Breaking Change the gridID property is now deprecated. Please, use column.grid.id instead.
igxCombo
- Breaking Change combo.value is now only a getter.
- Feature added support for templating the default input group of the component. The igx-combo now allows for igx-prefix, igx-suffix,igx-hint and [igxLabel] components to be passed as ng-content and they will be renderer accordingly on the combo's input. Example:
```
    
    <igx-combo #myCombo [data]="myGenres">
        ...
        <label igxLabel>Genres</label>
        <igx-prefix><igx-icon>music_note</igx-icon></igx-prefix>
    </igx-combo>
```
- Feature the default combo 'clear' and 'toggle' icons can now be templated. Two new directives are added (with selector [igxComboClearIcon] and [igxComboToggleIcon]). Passing an ng-template with one of the directives will overwrite the default conent of the respective icon. Functionality will remain unaffected. Expample:
```
    
    <igx-combo #myCombo [data]="myGenres">
        ...
        <ng-template igxComboToggleIcon let-collapsed>
            <igx-icon>{{ collapsed ? 'remove_circle' : 'remove_circle_outline'}}</igx-icon>
        </ng-template>
    </igx-combo>
```

igxDropDown

IgxDropDownItemBase and it's descendants (of which IgxDropDownItem) have had their isSelected and isFocused properties deprecated. Instead, use selected and focused properties.
Added an @Input for the index property (such as the one coming from ngFor) of the IgxDropDownItem component. This deprecates the automatic index calculation.

    <igx-drop-down>
        <igx-drop-down-item *ngFor="let item of items; let i = index" [index]="i">
            {{ item.field }}
        </igx-drop-down-item>
    </igx-drop-down>

Feature IgxDropDownGroupComponent has been added. It allows for easier grouping of multi-level data, without the need of flattening it. The igx-drop-down-item-group tag accepts igx-drop-down-items and displays them in the appropriate grouped fashion.

    <igx-drop-down>
        <igx-drop-down-item-group *ngFor="let country of contries" [label]="country.name">
            <igx-drop-down-item *ngFor="let city of country.cities" [value]='city.refNo'>
                {{ city.name }}
            </igx-drop-down-item>
        </igx-drop-down-item-group>
    </igx-drop-down>

Theme Elevations & Shadows - Components with shadows, set by an elevation level or otherwise, are now fully configurable by the user via schema and/or theme properties. User can also provide a custom elevations set to component themes that support them.
- Breaking Change - The $search-shadow-color and $search-disabled-shadow-color properties on the igx-input-group-theme have been replaced with $search-resting-shadow and $search-disabled-shadow respectively. Use ng update to migrate automatically.
IgxTreeGridComponent
- We can now search in the treegrid's data by using the findNext and the findPrev methods and we can clear the search results with the clearSearch method.
IgxTextHighlightDirective
- IgxTextHighlightDirective.page input property is deprecated. rowIndex, columnIndex and page properties of the IActiveHighlightInfo interface are also deprecated. Instead, row and column optional properties are added.
igxDragDrop
- dragGhostHost input property added. Sets the element to which the dragged element will be appended. If not provided, the dragged element is appended to the body.
Column Hiding UI
- Behavioral Change - The UI now hides the columns whose disableHiding property is set to true instead of simply disabling them.
igxButton - New Button Style - Include outlined button style to support the latest material spec.
igxOverlay:
- igxOverlay.attach() method added. Use this method to obtain an unique Id of the created overlay where the provided component will be shown. Then call igxOverlay.show(id, settings?) method to show the component in overlay. The new attach method has two overloads:
  - attach(element: ElementRef, settings?: OverlaySettings): string - This overload will create overlay where provided element will be shown.
  - attach(component: Type<any>, settings?: OverlaySettings, moduleRef?: NgModuleRef<any>): string - Creates a ComponentRef from the provided component class to show in an overlay. If moduleRef is provided the service will use the module's ComponentFactoryResolver and Injector when creating the ComponentRef instead of the root ones.
- igxOverlay.show(component, settings) is deprecated. Use igxOverlay.attach() method to obtain an Id, and then call igxOverlay.show(id, settings) method to show a component in the overlay.
- IPositionStrategy exposes new method clone that clones the strategy instance with its settings.
igx-date-picker
- Feature Added dropdown mode to enable the input field value editing and spinning of the date parts as well as displaying a drop down calendar to select a date. Example:
```
  <igx-date-picker #editableDatePicker1 mode="dropdown" [value]="date" format="dd.MM.y" mask="M/d/y">
  </igx-date-picker>
```

Components roundness

Ignite UI for Angular now allows you to change the shape of components by changing their border-radius.
Here is the list of all components that have roundness functionality:

igx-badge
igx-buttongroup
igx-calendar
igx-card
igx-carousel
igx-chip

igx-drop-down
igx-expansion-panel
igx-input-group
igx-list
- igx-list-item
igx-navdrawer
igx-snackbar

igxTooltip

Breaking Change
The $button-roundness property on the igx-button-theme have been replaced for each button type with: $flat-border-radius,$raised-border-radius,$outline-border-radius,$fab-border-radius, $icon-border-radius.
The$roundness property on the igx-chip-theme have been replaced with $border-radius.
The$roundness property on the iigx-tooltip-theme have been replaced with $border-radius.

7.1.5

Features

igxGrid
- Group By
  - The collapse/expand icons have new orientantion to display the action that will be performed when clicked. When an icon points up clicking on it would result in collapsing the related group row and when it points down clicking on it would expand the group row.
  - The collapse/expand all icons have also been updated to reflect the new group row icons better.

- Expanding/collapsing tree levels can now be performed also by using Alt + Arrow Up/Down to reflect the new icons.
Remove CSS Normalization - Some users were complaining we reset too many browser styles - lists and heading styles in particular. We no longer do CSS normalization on an application level. Users who depended on our CSS browser normalization will have to handle that on their own going forward.
igxOverlayService - the height of the shown element/component is not cached anymore. The height will be calculated each time position method of position strategy is called.
igxOverlayService
- onClosing event arguments are of type OverlayClosingEventArgs that adds an optional event property with the original DOM event. The browser event is available when closing of the overlay is caused by an outside click. This also affects all components and directives that use igxOverlay service - igxToggle, igxDropDown, igxCombo, igxSelect and igxAutocomplete. When they emit their respective onClosing event, the arguments are of type CancelableBrowserEventArgs, including the optional browser event.

IgxTimePickerComponent: in addition to the current dialog interaction mode, now the user can select or edit a time value, using an editable masked input with a dropdown.
IgxColumnComponent now accepts its templates as input properties through the markup. This can reduce the amount of code one needs to write when applying a single template to multiple columns declaratively. The new exposed inputs are:
- cellTemplate - the template for the column cells
- headerTemplate - the template for the column header
- cellEditorTemplate - the template for the column cells when a cell is in edit mode
```

7.1.0

Features

New component IgxBannerComponent:
- Allows the developer to easily display a highly templateable message that requires minimal user interaction (1-2 actions) to be dismissed. Read up more information about the IgxBannerComponent in the official documentation or the ReadMe
igxGrid
- Added a new igxToolbarCustomContent directive which can be used to mark an ng-template which provides a custom content for the IgxGrid's toolbar (#2983)
- Summary results are now calculated and displayed by default for each row group when 'Group By' feature is enabled.

- locale property added. Default value is en. All child components will use it as locale.
- Breaking change IgxSummaryOperand.operate() method is called with empty data in order to calculate the necessary height for the summary row. For custom summary operands, the method should always return an array of IgxSummaryResult with proper length.
IgxIconModule:
- Breaking change igxIconService is now provided in root (providedIn: 'root') and IgxIconModule.forRoot() method is deprecated.
- Breaking change glyphName property of the igxIconComponent is deprecated.
IgxColumnComponent:
- Breaking change the filters input now expects IgxFilteringOperand instance, instead of class ref. This way custom IgxFilteringOperands no longer need to be singleton, with defined instance method.
IgxMask:
- placeholder input property is added to allow developers to specify the placeholder attribute of the host input element that the igxMask is applied on;
- displayValuePipe input property is provided that allows developers to additionally transform the value on blur;
- focusedValuePipe input property is provided that allows developers to additionally transform the value on focus;
IgxTreeGrid:
- Batch editing - an injectable transaction provider accumulates pending changes, which are not directly applied to the grid's data source. Those can later be inspected, manipulated and submitted at once. Changes are collected for individual cells or rows, depending on editing mode, and accumulated per data row/record.
- You can now export the tree grid both to CSV and Excel.
- The hierarchy and the records' expanded states would be reflected in the exported Excel worksheet.
- Summaries feature is now supported in the tree grid. Summary results are calculated and displayed for the root level and each child level by default.
IgxOverlayService:
- ElasticPositioningStrategy added. This strategy positions the element as in Connected positioning strategy and resize the element to fit in the view port in case the element is partially getting out of view.

Features

igxGrid
- Group By
  - The collapse/expand icons have new orientantion to display the action that will be performed when clicked. When an icon points up clicking on it would result in collapsing the related group row and when it points down clicking on it would expand the group row.
  - The collapse/expand all icons have also been updated to reflect the new group row icons better.
  - Group rows now can be expanded/collapsed using Alt + Arrow Up/Down to reflect the new icons.
igxTreeGrid
- The collapse/expand icons have new orientantion to display the action that will be performed when clicked. When an icon points up clicking on it would result in collapsing the related tree grid level and when it points down clicking on it would expand the tree grid level.
- Expanding/collapsing tree levels can now be performed also by using Alt + Arrow Up/Down to reflect the new icons.

6.2.3

igxGrid
- resourceStrings property added, which allows changing/localizing strings for component. If a new instance is set, the changes will be applied to the particular instance of the component:
```
    this.grid.resourceStrings = {
        igx_grid_filter: 'My filter',
        igx_grid_filter_row_close: 'My close'

6.2.0

Updated typography following the Material guidelines. Type system is now also optional and can be applied via class to the desired containers. #2112
- Breaking change: Applications using Ignite UI for Angular now require the igx-typography class to be applied on wrapping element, like the body element for instance.
Display density can be specified by using the injection token DisplayDensityToken and providing a value (comfortable, cosy or compact) on an application or a component level.

Setting display density on a component level:
```
@Component({
...
providers: [{ provide: DisplayDensityToken, useValue: { displayDensity: DisplayDensity.compact} }]
})
```
igx-input-group
- The igx-input-group control's display density can be explicitly set by using the displayDensity input.
```
<igx-input-group [displayDensity]="'cosy'"> ... </igx-input-group>
```
igx-drop-down:
- Added a new boolean argument cancel to the onSelection ISelectionEventArgs. Its default value is false, in case it is set to true, the drop down selection is invalidated.
igxIcon:
- Breaking change glyphName property is removed from IgxIconComponent. For Material icons the icon name should be explicitly defined between the opening and closing tags. Font Awesome icons should use the name property now.
- Added support for custom SVG icons. Register the SVG icons with the IgxIconService and use IgxIconComponent's name and fontSet properties to visualize the icon.
Transaction Provider - TransactionService is an injectable middleware that a component can use to accumulate changes without affecting the underlying data. The provider exposes API to access, manipulate changes (undo and redo) and discard or commit all to the data. For more detailed information, see the README.
igxTreeGrid:
- New IgxTreeGridComponent added.
- The igxTreeGrid is used to display and manipulate hierarchical data with consistent schema, formatted as a table and provides a line of advanced features such as sorting, filtering, editing, column pinning, column moving, column hiding, paging and others.
- The igxTreeGrid provides two ways of defining the relations among our data objects - by using a child collection for every data object or by using primary and foreign keys for every data object.
- For more details on using the igxTreeGrid, take a look at the official documentation.
igxGrid:
- Breaking change onGroupingDone - The array of ISortingExpression can now be accessed through the expressions event property. Two new properties have been added to the event arguments - groupedColumns and ungroupedColumns. They provide references to arrays of IgxColumnComponent that hold the columns which have changed their state because of the last grouping/ungrouping operation.
- Breaking change onEditDone event is renamed to onCellEdit and new cell editing events are introduced: onCellEditEnter and onCellEditCancel. When row editing is enabled, the corresponding events are emitted by the grid - onRowEditEnter, onRowEdit, onRowEditCancel. All these events have arguments that are using the IGridEditEventArgs interface.
- Row editing - allows modification of several cells in the row, before submitting, at once, all those changes to the grid's data source. Leverages the pending changes functionality of the new transaction provider.
```
<igx-grid [data]="data" [rowEditable]="true">
    <igx-column field="ProductName"></igx-column>
    <igx-column field="ReleaseDate"></igx-column>
</igx-grid>
```
- Batch editing - an injectable transaction provider accumulates pending changes, which are not directly applied to the grid's data source. Those can later be inspected, manipulated and submitted at once. Changes are collected for individual cells or rows, depending on editing mode, and accumulated per data row/record.
```
@Component({
    providers: [{ provide: IgxGridTransaction, useClass: IgxTransactionService }],
    selector: "app-grid-with-transactions",
    template: "<ng-content></ng-content>"
})
export class GridWithTransactionsComponent { }
```
- A new boolean hideGroupedColumns input controls whether the grouped columns should be hidden as well (defaults to false).
- Breaking change cellClasses input on IgxColumnComponent now accepts an object literal to allow conditional cell styling.
- Exposing a mechanism for cells to grow according to their content.
- sortStrategy input exposed to provide custom sort strategy for the IgxColumnComponent. The custom strategy should implement the ISortingStrategy interface, or can extend the base SortingStrategy class and override all or some of its public/protected members.
- New quick filtering functionality is implemented. Filtering icon is removed from column header and a filtering row is introduced in the grid's header.
igxFor
- Added support for variable heights.
igx-datePicker selector is deprecated. Use igx-date-picker selector instead.
igxOverlay:
- OverlaySettings now also accepts an optional outlet to specify the container where the overlay should be attached.
- when show and hide methods are called onAnimation event fires. In the arguments of this event there is a reference to the animationPlayer, animationType (either open or close) and to the overlay id.
- if you call show/hide methods of overlay, while opening/closing animation is still ongoing, the animation will stop and respective open/close animation will start.
igxToggleAction new outlet input controls the target overlay element should be attached. Provides a shortcut for overlaySettings.outlet.
IgxOverlayOutlet directive introduced to mark an element as an igxOverlay outlet container. ReadMe
igxButtonGroup
- Added the ability to define buttons directly in the template
igx-time-picker:
- igxTimePickerTemplate - new directive which should be applied on the child <ng-template> element when IgxTimePickerComponent's input group is retemplated.
igx-datePicker:
- igxDatePickerTemplate - new directive which should be applied on the child <ng-template> element when IgxDatePickerComponent's input group is retemplated.
- Introduced disabledDates. This property is exposed from the igx-calendar component.
- Introduced specialDates. This property is exposed from the igx-calendar component.
- Introduced deselectDate method added that deselects the calendar date.
IgxTextHighlightDirective: The highlight method now has a new optional parameter called exactMatch (defaults to false).
- If its value is false, all occurrences of the search text will be highlighted in the group's value.
- If its value is true, the entire group's value should equals the search text in order to be highlighted (caseSensitive argument is respected as well).
IgxGrid: The findNext and findPrev methods now have a new optional parameter called exactMatch (defaults to false).
- If its value is false, all occurrences of the search text will be highlighted in the grid's cells.
- If its value is true, the entire value of each cell should equals the search text in order to be highlighted (caseSensitive argument is respected as well).
IgxChip
- Introduced event argument types to all EventEmitter @Outputs.
- Breaking change onSelection's EventEmitter interface property nextStatus is renamed to selected.
- Breaking change Move the location of where the chip suffix is positioned. Now it is between the content and the remove button making the button last element if visible by default.
- Breaking change Remove the chip connector rendered when using the igxConnector directive that is also removed.
- Breaking change The chip theme has been rewritten. Most theme input properties have been renamed for consistency and better legibility. New properties have been added. Please, refer to the updated igx-chip-theme documentation to see all updates.
- Exposed original event that is responsible for triggering any of the events. If triggered by the API it is by default null.
- Added data input for storing any data related to the chip itself.
- Added select icon with show/hide animation to indicate when a chip is being selected with ability to customize it while retaining the chip Material Design styling.
- Added selectIcon input to set custom template for the select icon.
- Update chip styling to match Material Design guidelines.
- Rework of the chip content styling so now by default text inside is styled to match the chip Material Design styling.

- Added removeIcon input so a custom template cane be set for the remove button icon.
IgxChipArea
- Introduced event argument types to all EventEmitter @Outputs.
- Exposed original event that is responsible for triggering any of the events. If triggered by the API it is by default null.
IgxCombo
- Added the following directives for TemplateRef assignment for combo templates (item, footer, etc.):
  - Added IgxComboItemDirective. Use [igxComboItem] in markup to assing a TemplateRef to combo.itemTemplate.
  - Added IgxComboHeaderDirective. Use [igxComboHeader] in markup to assing a TemplateRef to combo.headerTemplate.
  - Added IgxComboFooterDirective. Use [igxComboFooter] in markup to assing a TemplateRef to combo.footerTemplate.
  - Added IgxComboEmptyDirective. Use [igxComboEmpty] in markup to assing a TemplateRef to combo.emptyTemplate.
  - Added IgxComboAddItemirective. Use [igxComboAddItem] in markup to assing a TemplateRef to combo.addItemTemplate.
  - Added IgxComboHeaderItemDirective. Use [igxComboHeaderItem] in markup to assing a TemplateRef to combo.headerItemTemplate.
- Breaking change Assigning templates with the following template ref variables is now deprecated in favor of the new directives: #itemTemplate, #headerTemplate, #footerTemplate, #emptyTemplate, #addItemTemplate, #headerItemTemplate.
- Breaking change height property is removed. In the future IgxInputGroup will expose an option that allows custom sizing and then IgxCombo will use the same functionality for proper styling and better consistency.
IgxDropDown
- Breaking change allowItemsFocus default value is changed to false.
- Added value input to IgxDropDownItemComponent definition. The property allows data to be bound to a drop-down item so it can more easily be retrieved (e.g. on selection)
igx-calendar:
- Introduced disabledDates property which allows a user to disable dates based on various rules: before or after a date, weekends, workdays, specific dates and ranges. The disabled dates cannot be selected and have a distinguishable style.
- Introduced specialDates property which allows a user to mark dates as special. They can be set by using various rules. Their style is distinguishable.
- Introduced deselectDate method added that deselects date(s) (based on the selection type)
igxExpansionPanel:
- component added. igxExpansionPanel provides a way to display more information after expanding an item, respectively show less after collapsing it. For more detailed information see the official documentation.
IgxList:
- the control now supports ng-templates which are shown "under" a list item when it is left or right panned. The templates are distinguished using the igxListItemLeftPanning and igxListItemRightPanning directives set on the templates.
- the IgxList's onLeftPan and onRightPan events now have an argument of type IListItemPanningEventArgs (instead of IgxListItemComponent). The event argument has the following fields:
  - item of type IgxListItemComponent
  - direction of type IgxListPanState
  - keepItem of type boolean
igxTooltip and igxTooltipTarget directives:
- Added IgxTooltipDirective.
  - An element that uses the igxTooltip directive is used as a tooltip for a specific target (anchor).
  - Extends IgxToggleDirective.
  - Exported with the name tooltip.
- Added IgxTooltipTargetDirective.
  - An element that uses the igxTooltipTarget directive is used as a target (anchor) for a specific tooltip.

  - Exported with the name tooltipTarget.
- Both new directives are used in combination to set a tooltip to an element. For more detailed information, see the README.
igxToggle:
- Introduced reposition method which allows a user to force toggle to reposition according its position strategy.
IgxDrag and IgxDrop directives available.
- IgxDrag allows any kind of element to be moved/dragged around the page without changing its position in the DOM. Supports Desktop/Mixed/Touch environments.
- IgxDrop allows any element to act as a drop area where any igxDrag element can be dragged into and dropped. Includes default logic that moves the dropped element from its original position to a child of the igxDrop element.
- Combined they provide a way to move elements around the page by dragging them. For more detail see the README.
IgxGrid keyboard navigation When you focus a specific cell and press one of the following key combinations, the described behaviour is now performed:
- Ctrl + Arrow Key Up - navigates to the first cell in the current column;
- Ctrl + Arrow Down - navigates to the last cell in the current column;
- Home - provide the same behavior as Ctrl + Arrow Left - navigates to the first cell from the current row;
- End - provide the same behavior as Ctrl + Arrow Right - navigates to the last cell from the current row;
- Ctrl + Home - navigates to the first cell in the grid;
- Ctrl + End - navigates to the last cell in the grid;
- Tab - sequentially move the focus over the next cell on the row and if the last cell is reached move to next row. If next row is group row the whole row is focused, if it is data row, move focus over the first cell;
- Shift + Tab - sequentially move focus to the previous cell on the row, if the first cell is reached move the focus to the previous row. If previous row is group row focus the whole row or if it is data row, focus the last cell of the row;
- Space over Cell - if the row is selectable, on keydown space triggers row selection
- Arrow Left over GroupRow - collapse the group row content if the row is not already collapsed;
- Arrow Right over GroupRow - expand the group row content if the row is not already expanded;
- on mouse wheel the focused element is blurred;
- Breaking change space handler for the group row has been removed; so Space does not toggle the group row;
- Breaking change cell selection is preserved when the focus is moved to group row.
- Introduced onFocusChange event. The event is cancelable and output argument from type IFocusChangeEventArgs;
- For more detailed information see the official keyboard navigation specification.

6.1.9

General

sortStrategy input exposed to provide custom sort strategy for the IgxColumnComponent. The custom strategy should implement the ISortingStrategy interface, or can extend the base DefaultSortingStrategy class and override all or some of its public/protected members.
The previously optional ignoreCase and strategy of the ISortingExpression interface are no longer optional. In order to use our default sorting strategy in expressions built programmatically, you need to pass DefaultSortingStrategy.instance() or any implementation of the ISortingStrategy interface.
groupingComparer input exposed to provide custom grouping compare function for the IgxColumnComponent. The function receives two values and should return 0 if they are to considered members of the same group.

igxGrid filtering operands
igxGrid
- Breaking change filter_multiple method is removed. filter method and filteringExpressionsTree property could be used instead.
- Breaking change filter method has new signature. It now accepts the following parameters:
  - name - the name of the column to be filtered.
  - value - the value to be used for filtering.
  - conditionOrExpressionTree - (optional) this parameter accepts object of type IFilteringOperation or IFilteringExpressionsTree. If only a simple filtering is required a filtering operation could be passes (see bellow for more info). In case of advanced filtering an expressions tree containing complex filtering logic could be passed.
  - ignoreCase - (optional) - whether the filtering would be case sensitive or not.
- Breaking change onFilteringDone event now have only one parameter - IFilteringExpressionsTree which contains the filtering state of the filtered column.
- filter_global method clears all existing filters and applies the new filtering condition to all grid's columns.
- filtering operands:
  - Breaking change IFilteringExpression condition property is no longer a direct reference to a filtering condition method, instead it's a reference to an IFilteringOperation
  - 5 filtering operand classes are now exposed
    - IgxFilteringOperand is a base filtering operand, which can be inherited when defining custom filtering conditions
    - IgxBooleanFilteringOperand defines all default filtering conditions for boolean types
    - IgxNumberFilteringOperand defines all default filtering conditions for numeric types
    - IgxStringFilteringOperand defines all default filtering conditions for string types
    - IgxDateFilteringOperand defines all default filtering conditions for Date types
  - IgxColumnComponent now exposes a filters property, which takes an IgxFilteringOperand class reference
    - Custom filters can now be provided to grid columns by populating the operations property of the IgxFilteringOperand with operations of IFilteringOperation type

export class IgxCustomFilteringOperand extends IgxFilteringOperand {
    // Making the implementation singleton
    private static _instance: IgxCustomFilteringOperand = null;

    protected constructor() {
        super();
        this.operations = [{
            name: 'custom',
            logic: (target: string) => {
                return target === 'My custom filter';
            }
        }].concat(this.operations); // Keep the empty and notEmpty conditions from base
    }

    // singleton
    // Must implement this method, because the IgxColumnComponent expects it
    public static instance(): IgxCustomFilteringOperand {
        return this._instance || (this._instance = new this());
    }
}

igxGrid now supports grouping of columns enabling users to create criteria for organizing data records. To explore the functionality start off by setting some columns as groupable:
```
<igx-grid [data]="data">
    <igx-column [field]="'ProductName'"></igx-column>
    <igx-column [field]="'ReleaseDate'" [groupable]="true"></igx-column>
</igx-grid>
```
For more information, please head over to igxGrid's ReadMe or the official documentation.
igxGrid now supports multi-column headers allowing you to have multiple levels of columns in the header area of the grid. For more information, head over to official documentation
igxGrid theme now has support for alternating grid row background and text colors.
igxGrid now has a toolbar (shown using the showToolbar property) which contains the following features:
- title (specified using the toolbarTitle property)
- column hiding feature (enabled using the columnHiding property)
- column pinning feature (enabled using the columnPinning property)

The deprecated igxForRemote input for the igxFor directive is now removed. Setting the required totalItemCount property after receiving the first data chunk is enough to trigger the required functionality.

6.0.4

igxRadioGroup directive introduced. It allows better control over its child igxRadio components and support template-driven and reactive forms.
Fixed ReactiveForms validations support for IgxInputGroup. Related issue.

6.0.3

The ng update igniteui-angular migration schematics now also update the theme import path in SASS files. #1582

6.0.1

Introduced migration schematics to integrate with the Angular CLI update command. You can now run

ng update igniteui-angular

in existing projects to both update the package and apply any migrations needed to your project. Make sure to commit project state before proceeding. Currently these cover converting submodule imports as well as the deprecation of igxForRemote and rename of igx-tab-bar to igx-bottom-nav from 6.0.0.

Breaking changes:

Removed submodule imports. All imports are now resolved from the top level igniteui-angular package. You can use ng update igniteui-angular when updating to automatically convert existing submodule imports in the project.
Summary functions for each IgxSummaryOperand class has been made static. So now you can use them in the following way:

import { IgxNumberSummaryOperand, IgxSummaryOperand } from "igniteui-angular";
class CustomSummary extends IgxSummaryOperand {
constructor() {
  super();
}
public operate(data?: any[]) {
  const result = super.operate(data);
  result.push({
    key: "Min",
    label: "Min",
    summaryResult: IgxNumberSummaryOperand.min(data)
  });
  return result;
}
}

6.0.0

Theming - You can now use css variables to style the component instances you include in your project.
Added onDoubleClick output to igxGrid to emit the double clicked cell.

igx-tab-bar changes
- Breaking changes: IgxTabBarComponent is renamed to IgxBottomNavComponent and IgxTabBarModule is renamed to IgxBottomNavModule.
- igx-tab-bar selector is deprecated. Use igx-bottom-nav selector instead.
igx-tabs component added
- igx-tabs allows users to switch between different views. The igx-tabs component places the tabs headers at the top and allows scrolling when there are multiple tab items outside the visible area. Tabs are ordered in a single row above their associated content.
- For more information navigate to ReadMe.
Added column pinning in the list of features available for igxGrid. Pinning is available though the API. Try the following:
```
const column = this.grid.getColumnByName(name);
column.pin();
```
For more information, please head over to igxGrid's ReadMe or the official documentation.
Added summaries feature to igxGrid, enabled on a per-column level. Grid summaries gives you a predefined set of default summaries, depending on the type of data in the column. For more detailed information read igxGrid's ReadMe or see the official documentation.
Added columnWidth option to igxGrid. The option sets the default width that will be applied to columns that have no explicit width set. For more detailed information read igxGrid's ReadMe
Added API to igxGrid that allows for vertical remote virtualization. For guidance on how to implement such in your application, please refer to the official documentation
Added smooth scrolling for the igxForOf directive making the scrolling experience both vertically and horizontally much more natural and similar to a native scroll.
Added onCellClick event.

igxForOf now requires that its parent container's overflow is set to hidden and position to relative. It is recommended that its height is set as well so that the display container of the virtualized content can be positioned with an offset inside without visually affecting other elements on the page.

<div style='position: relative; height: 500px; overflow: hidden'>
    <ng-template igxFor let-item [igxForOf]="data" #virtDirVertical
            [igxForScrollOrientation]="'vertical'"
            [igxForContainerSize]='"500px"'
            [igxForItemSize]='"50px"'
            let-rowIndex="index">
            <div style='height: 50px;'>{{rowIndex}} : {{item.text}}</div>
    </ng-template>
</div>

Removed the dirty local template variable previously exposed by the igxFor directive.
The igxForRemote input for the igxFor directive is now deprecated. Setting the required totalItemCount property after receiving the first data chunk is enough to trigger the required functionality.
the igx-icon component can now work with both glyph and ligature-based icon font sets. We've also included a brand new Icon Service, which helps you create aliases for the icon fonts you've included in your project. The service also allows you to define the default icon set used throughout your app.
Added the option to conditionally disable the igx-ripple directive through the igxRippleDisabled property.
Updated styling and interaction animations of the igx-checkbox, igx-switch, and igx-radio components.
Added indeterminate property and styling to the igx-checkbox component.

You can now use any element as label on the igx-checkbox, igx-switch, and igx-radio components via the aria-labelledby property.
You can now have invisible label on the igx-checkbox, igx-switch, and igx-radio components via the aria-label property.
Added the ability to toggle the igx-checkbox and igx-switch checked state programmatically via toggle method on the component instance.
Added the ability to select an igx-radio programmatically via select method on the component instance.
Fixed a bug on the igx-checkbox and igx-radio components where the click event was being triggered twice on click.
Fixed a bug where the igx-checkbox, igx-switch, and igx-radio change event was not being triggered on label click.
igxМask directive added
- igxМask provide means for controlling user input and formatting the visible value based on a configurable mask rules. For more detailed information see igxMask README file

igxExcelExportService and igxCSVExportService added. They add export capabilities to the igxGrid. For more information, please visit the igxExcelExportService specification and the igxCSVExportService specification.
General
- Added event argument types to all EventEmitter @Outputs. #798 #740
- Reviewed and added missing argument types to the following EventEmitters
  - The igxGrid onEditDone now exposes arguments of type IGridEditEventArgs. The arguments expose row and cell objects where if the editing is performed on a cell, the edited cell and the row the cell belongs to are exposed. If row editing is performed, the cell object is null. In addition the currentValue and newValue arguments are exposed. If you assign a value to the newValue in your handler, then the editing will conclude with the value you've supplied.
  - The igxGrid onSelection now correctly propagates the original event in the IGridCellEventArgs.
- Added jsZip as a Peer Dependency.
primaryKey attribute added to igxGrid
- primaryKey allows for a property name from the data source to be specified. If specified, primaryKey can be used instead of index to indentify grid rows from the igxGrid.rowList. As such, primaryKey can be used for selecting rows for the following igxGrid methods - deleteRow, updateRow, updateCell, getCellByColumn, getRowByKey
- primaryKey requires all of the data for the specified property name to have unique values in order to function as expected.
- as it provides a unique identifier for each data member (and therefore row), primaryKey is best suited for addressing grid row entries. If DOM virtualization is in place for the grid data, the row index property can be reused (for instance, when filtering/sorting the data), whereas primaryKey remains unique. Ideally, when a persistent reference to a row has to be established, primaryKey should be used.
Theming
- Added a utilities module to the theming engine to allow for easier import of theming functions and mixins, such as igx-color, igx-palette, igx-elevation, etc. To import the utilities do @import '~igniteui-angular/core/styles/themes/utilities';

5.2.1

hammerjs and @types/hammerjs are removed from peerDependencies and were added as dependencies. So if you are using Igniteui-Angular version 5.2.1 or above it is enough to run npm install igniteui-angular in your project for getting started. For more detailed information see Ignite UI for Angular Getting Started
web-animations-js is added as Peer Dependency.
Theming bug fixes and improvements.
Use the following command to generate Ignite UI for Angular Themes documentation - npm run build:docs. Navigate to dist/docs/sass and open index.html file.

5.2.0

igxForOf directive added
- igxForOf is now available as an alternative to ngForOf for templating large amounts of data. The igxForOf uses virtualization technology behind the scenes to optimize DOM rendering and memory consumption. Virtualization technology works similar to Paging by slicing the data into smaller chucks which are swapped from a container viewport while the user scrolls the data horizontally/vertically. The difference with the Paging is that virtualization mimics the natural behavior of the scrollbar.
igxToggle and igxToggleAction directives added
- igxToggle allows users to implement toggleable components/views (eg. dropdowns), while igxToggleAction can control the igxToggle directive. Refer to the official documentation for more information.
- igxToggle requires BrowserAnimationsModule to be imported in your application.
Ignite UI for Angular Theming - comprehensive set of Sass functions and mixins will give the ability to easily style your entire application or only certain parts of it.
- Previously bundled fonts, are now listed as external dependencies. You should supply both the Material Icons and Titillium Web fonts yourself by either hosting or using CDN.
igx-grid changes
- The component now uses the new igxForOf directive to virtualize its content both vertically and horizontally dramatically improving performance for applications displaying large amounts of data.
- Data-bound Input property filtering changed to filterable:
```
<igx-grid [data]="data">
    <igx-column [field]="'ReleaseDate'" [header]="'ReleaseDate'"
        [filterable]="true" dataType="date">
    </igx-column>
</igx-grid>
```
- @HostBinding min-width added to IgxGridCellComponent and IgxGridHeaderCell
- The IgxGridCellComponent no longer has a value setter, but instead has an update modifier.
```
<ng-template igxCell let-cell="cell">
    {{ cell.update("newValue") }}
</ng-template>
```
- Class IgxGridFiltering renamed to IgxGridFilteringComponent
- The grid filtering UI dropdowns are now controlled by the igxToggle directive.
  - Make sure to import BrowserAnimationsModule inside your application module as igxToggle uses animations for state transition.
