The RadDiagram lets you turn off Cut, Copy, Paste, etc functionality, but there doesn't seem to be a way to turn off the Duplicate command.

How would I remove the Ctrl+D key binding from the RadDiagram?

Thanks

Hi Terry,

In order to achieve your requirement you actually can predefine the duplicate command that has been executed on Ctrl+D combination. You can do this with the following snippet:

private static void CanExecuteDuplicate(object sender, CanExecuteRoutedEventArgs e)
{
    e.CanExecute = true;
}
 
private static void ExecuteDuplicate(object sender, ExecutedRoutedEventArgs e)
{
    return;
}
 
static MainWindow()
{
    var duplicate = new CommandBinding(DiagramCommands.Duplicate, ExecuteDuplicate, CanExecuteDuplicate);
    CommandManager.RegisterClassCommandBinding(typeof(RadDiagram), duplicate);
}
By doing so you will need to implement custom duplication logic inside the ExecuteDuplicate() method. Please note that this method will be invoked when the e.CanExecute is set to True, otherwise the default duplication logic will be triggered.

Please give this approach a try and let us know if you need any further assistance.
