RadialMenuItem Commands

RadRadialMenuItem provides 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 set through the CommandParameter property of the RadialMenuItem.

Create a Command

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

  1. First, create a class that implements the ICommand interface. Example 1 shows a sample implementation.

    Example 1: Creating a command

        public class CustomItemCommand : ICommand 
        { 
            public bool CanExecute(object parameter) 
            { 
                var radialMenuItem = parameter as RadRadialMenuItem; 
                if (radialMenuItem != null) 
                { 
                    // perform custom logic here 
                } 
                return true; 
            } 
     
            public void Execute(object parameter) 
            { 
                var radialMenuItem = parameter as RadRadialMenuItem; 
                if (radialMenuItem != null) 
                { 
                    // perform custom logic here                 
                } 
            } 
     
            public event EventHandler CanExecuteChanged; 
        } 
    
  2. Add an instance of the custom command class to the Resources of the UserControl.

    Example 2: Adding the command to the Resources

        <UserControl.Resources> 
            <local:CustomItemCommand x:Key="CustomItemCommand"/> 
        </UserControl.Resources> 
    
  3. Bind the Command property of the RadialMenuItem to the instance of the custom command as shown in Example 3.

    Example 3: Bind the command

        <telerik:RadRadialMenu> 
            <telerik:RadRadialMenuItem Header="Item 1" Command="{StaticResource CustomItemCommand}"  
            CommandParameter="{Binding RelativeSource={RelativeSource Self}}" /> 
            <telerik:RadRadialMenuItem Header="Item 2" Command="{StaticResource CustomItemCommand}"  
            CommandParameter="{Binding RelativeSource={RelativeSource Self}}" /> 
            <telerik:RadRadialMenuItem Header="Item 3" Command="{StaticResource CustomItemCommand}"  
            CommandParameter="{Binding RelativeSource={RelativeSource Self}}" /> 
        </telerik:RadRadialMenu>
