Custom FlyoutGroupHeader Command

Examples 1 and 2 show how to create a class that inherits from DataGridCommand and add it to the Commands collection.

Example 1: Creating a custom FlyoutGroupHeader Command

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); 
    } 
} 

Example 2: Adding the custom Command to the Commands collection

<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>
