[Closed] DotNet NumericUpDown Control

hello guys! i have some another problem with NumericUpDown control…
there is now feedback on ‘scroll’ event… if i add to floatspinner.ms code

	
on upDownCtrl Scroll ev do
(
    showProperties ev
    print "123"
)

there is no action if i scroll the control (by mouse or by up/down buttons). The event is not identified…
and i want to use (ev.NewValue/ev.OldValue) for some needs, which i can bring from the scroll event. Thank you
