Question

KeyPreview on a UserControl

Asked by: oak29

I am having a hard time getting a grid to recognize the keypress event.  I think it is because I have the grid in a usercontrol.  Is there a KeyPreview Property for a usercontrol?  I have this Usercontrol in a windows form "wrapper".  I use this wrapper to wrap all of my usercontrols that I develop as the the screens.

Is there a KeyPreview Property for a usercontrol?
no

you need to raise a event from your usercontrol

ie

in your user control
Public Event keypress(KeyAscii As Integer)

Private Sub Grid1_KeyPress(KeyAscii As Integer)
RaiseEvent keypress(KeyAscii)
End Sub

 

by: oak29Posted on 2009-08-28 at 11:58:47ID: 25210599

So where does this event live that I am raising?  Is it on the windows form wrapper?  

 

by: EDDYKTPosted on 2009-08-28 at 13:32:46ID: 25211338

your container, in this case it is your form
the usercontrol will raise this event to your form

 

by: oak29Posted on 2009-08-28 at 13:46:39ID: 31614332

I see.  That should work great!  It will be very generic so my form won't need to know anything about my user control and I will be able to apply this to my other user controls if the need arises!
