FlyoutGroupHeader Command

Updated on Mar 26, 2026

The FlyoutGroupHeader command is associated with the Tap event that occurs over a group header in the flyout.

Execution Parameter

The execution parameter is of type FlyoutGroupHeaderTapContext and exposes the following properties:

• Action—Gets the DataGridFlyoutGroupHeaderTapAction value that identifies the meaning of the Tap event. The possible values are ChangeSortOrder and RemoveDescriptor.
• Descriptor—Gets the GroupDescriptorBase instance associated with the command.

Custom FlyoutGroupHeader Command

The following examples show how to create a class that inherits from the DataGridCommand and add it to the Commands collection.

Create a Custom FlyoutGroupHeader Command

C#

public class CustomFlyoutGroupHeaderTap : DataGridCommand
{
	public CustomFlyoutGroupHeaderTap()
	{
		this.Id = CommandId.FlyoutGroupHeaderTap;
	}

	public override bool CanExecute(object parameter)
	{
		//put your custom logic here
		return true;
	}

	public override void Execute(object parameter)
	{
		var context = parameter as FlyoutGroupHeaderTapContext;
		//put your custom logic here

		this.Owner.CommandService.ExecuteDefaultCommand(CommandId.FlyoutGroupHeaderTap, context);
	}
}

Add the Custom Command to the Commands Collection

XAML

<Grid xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid">
	<grid:RadDataGrid Width="600" Height="460" x:Name="grid" Hold>
		<grid:RadDataGrid.Commands>
			<local:CustomFlyoutGroupHeaderTap/>
		</grid:RadDataGrid.Commands>
	</grid:RadDataGrid>
</Grid>
