Prevent node deletion

Is there a way to prevent deleting a node by pressing the key combination <shift><delete>?

The NodeDeleting event is only called with the key <delete>. I can catch that one. The event OnKeyDown is not called at all.

Thanks in advance

Apparently that's another shortcut for ApplicationCommands.Cut, along with Ctrl+X. The diagram handles it internally by calling CutToClipboard method, without validating individual nodes in the selection. Try replacing the command binding as in this post -
