Telerik UI for Windows 8 XAML

The RadialMenuItem has a Command property that can be bound to an ICommand implementation. The execution of the command is triggered by click/tap event. The parameter passed to the command is of RadialMenuItemContext type and exposes the following properties:

  • TargetElement: This is the element that uses the RadRadialMenu as a context menu.

  • MenuItem: This is the RadialMenuItem that has initiated the command.

  • CommandParameter: The command parameter passed by the RadialMenuItem.


Here is an example demonstrating how to add a custom command to a RadialMenuItem.

  1. First, create a class that implements the ICommand interface.

    C# Copy imageCopy
    public class CustomItemCommand : ICommand
        public bool CanExecute(object parameter)
            var item = parameter as RadialMenuItemContext;
            // perform custom logic here
            return true;
        public void Execute(object parameter)
            var context = parameter as RadialMenuItemContext;
            var target = context.TargetElement;
            var item = context.MenuItem;
            var commandParameter = context.CommandParameter;
            // perform custom logic here
        public event EventHandler CanExecuteChanged;
  2. Add an instance of the custom command class to the Resources of the Page.

    XAML Copy imageCopy
        <local:CustomItemCommand x:Key="customCommand"/>
  3. Bind the Command property of the RadialMenuItem to the instance of the custom command.

    XAML Copy imageCopy
    <TextBlock Text="Some Text">
                <telerikPrimitives:RadialMenuItem Header="Item 1" Command="{StaticResource customCommand}"/>
                <telerikPrimitives:RadialMenuItem Header="Item 2" Command="{StaticResource customCommand}"/>
            <telerikPrimitives:RadialMenuTriggerBehavior AttachTriggers="Focused" />
