What does setting to e.Handled = True in OnKeyUp do?

[**Developer**]

I have a usercontrol that contains the following.

To my surprise the form containing this control get KeyUp events.

Help says that for KeyPress setting e.Handled = True suppresses KeyPress
events but say very little about KeyUp.

What does setting to Handled do?



In the Control I also continue to get KeyPress and KeyUp events.

In them I also have the same code to set e.Handled = True

Thanks



Protected Overrides Sub OnKeyUp(ByVal e As
System.Windows.Forms.KeyEventArgs)

If mReadOnly Then

e.Handled = True

Else

snip...

End If

MyBase.OnKeyUp(e)

End Sub

Same thing. Suppresses the event from there onwards. ie. other controls
wanting it won't get it.

But that's my confusion. I get the event on the form after I set e.Handled =
True in the control.

Thanks
