Hello,

I'd like to override the keyboard shortcuts for copy, cut and paste because there are some very specific things that I need to do to copy/paste my objects. I've tried overriding the OnKeyDown event, but the commands never hit that method, even though other ctrl commands (ex. ctrl+s) do. Is there a way to have this this control returned to me when I set AllowCopy, AllowCut and AllowPaste to False?

Thanks,
Zak

Hi Zak,
Could you please elaborate a little bit more on what exactly are you trying to achieve ? There are a couple of ways to override the default copy, cut and paste commands but it depends on your specific scenario:
1) You could add your own command binding for those commands:
static Example()
{
    var copyBinding = new CommandBinding(DiagramCommands.Copy, OnCopyExecute, OnCanCopy);
    CommandManager.RegisterClassCommandBinding(typeof(RadDiagram), copyBinding);
}
 
private static void OnCanCopy(object sender, CanExecuteRoutedEventArgs e)
{
    e.CanExecute = true;
    e.Handled = true;
}
 
private static void OnCopyExecute(object sender, ExecutedRoutedEventArgs e)
{
    // Do what you want.
}
2) You could override the Ctr + C (Ctr + V and Ctr + X) input bindings with an ApplicationCommands.NotACommand and this way they will be ignored and the key down events will be rised:
public Example()
{
    InitializeComponent();
    CommandManager.RegisterClassInputBinding(typeof(RadDiagram), new InputBinding(ApplicationCommands.NotACommand, new KeyGesture(Key.C, ModifierKeys.Control)));
I hope I was able to help you and if you have more questions feel free to ask.
