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>
