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.KeyEventA rgs)
If mReadOnly Then
e.Handled = True
Else
snip...
End If
MyBase.OnKeyUp( e)
End Sub 4 6980
you are calling mybase.onkeyup, which will always raise the event. you are
not handling the event, you are simply overriding it.

when the event is raised, it will check cause subsequent handlers to not be
called. It needs to be set inside of an event handler though, and you are
not.

If a KeyUp event takes place on my form, how can I keep the
KeyDown/KeyPress/KeyUp events from being run on the control event itself.
I tried putting e.Handled=true; at the end of my KeyUp event, but that
doesn't seem to work. Am I missing something? It appears that the KeyUp
event on my control still runs. Help!

Hi,
In my .Net 1.1 C# windows form, I have a DataGrid DG1.
The DG1 have a column dc1 which format is TextBox.
And I want to check the whave value I have typed in.
My question is the new value doesn't really go into the DataGrid1's dc1
until some event occurs (e.g., KeyPress, KeyDown, ...)
but I don't know what the event is.
Is it possible to observe what event I'm in?
Thanks for help.
