Hi Duncan,
I don't think you can because they haven't exposed the KeyEventArgs parameter. If you try to manually map a user defined event the compiler complains: "'wABC' does not contain a definition for 'ue123' and no extension method 'ue123' accepting a first argument of type 'wABC' could be found". I tried mapping it as a dw event and then as a window private function without success. Both methods yield the same error.
Here's the dw event logic I tried. Maybe you'll see something I missed...
XAML dw property
KeyDown="ue_dwnkey"
Script ue_dwnkey event
Parms
System.Object sender
System.Windows.Input.KeyEventArgs e
choose case e.Key
case System.Windows.Input.Key.Down!, System.Windows.Input.Key.Up!
e.handled = true
end choose
hth,
Mark
