Blazor TreeView

February 16, 2026 · View on GitHub

This example shows how to implement a custom filter that reacts to the TreeViewNode’s Text when it is split by a comma and applies custom highlighting.

The filter accepts the NavigationFilterInfo structure to obtain the FilterString value and uses a regular expression to parse the filter string. The NodeTextTemplate uses a regular expression to apply custom highlighting.
