FilterButtonTap Command

Updated on Mar 26, 2026

The FilterButtonTap command handles the tap gesture over a Filter button. The default implementation will open the Filtering Flyout.

Execution Parameter

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

• AssociatedDescriptor—Gets the FilterDescriptorBase instance associated with the context. Typically, this is the PropertyFilterDescriptor already applied to the column instance.
• FirstFilterControl—Gets or sets the IFilterControl control that represents the UI used to generate the first FilterDescriptorBase.
• SecondFilterControl—Gets or sets the IFilterControl control that represents the UI used to generate the second FilterDescriptorBase.
• Column—Gets the DataGridColumn instance that owns the Filter button that is being tapped.

Custom FilterButtonTap 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 FilterButtonTap Command

C#

public class CustomFilterButtonTapCommand : DataGridCommand
{
	public CustomFilterButtonTapCommand()
	{
		this.Id = CommandId.FilterButtonTap;
	}

	public override bool CanExecute(object parameter)
	{
		var context = parameter as FilterButtonTapContext;
		// put your custom logic here
		return true;
	}

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

		this.Owner.CommandService.ExecuteDefaultCommand(CommandId.FilterButtonTap, 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:CustomFilterButtonTapCommand/>
		</grid:RadDataGrid.Commands>
	</grid:RadDataGrid>
</Grid>
