Windows.UI.Xaml.Controls.VirtualizingStackPanel.IsVirtualizing

Note

VirtualizingStackPanel.IsVirtualizing is an atypical attached property because it does not have a Set accessor, and thus is not really a XAML attached property with a markup usage. It uses the attached property model as a property store, but does not support an Extensible Application Markup Language (XAML) usage. Instead, the property serves as a sentinel that any VirtualizingStackPanel child element can check to determine whether that child is currently being represented as virtualized. To find out if an item is being virtualized, call GetIsVirtualizing, passing the item as the input parameter.
