Hello friends
I'm trying to perform event bubble on a user control from the example on
http://odetocode.com/Articles/94.aspx
but this example doesn't work... when I run the code it says BubbleControl
does not exist which makes sense as nothing was assigned to BubbleControl...
I'm just curious if I should assign because I did try assigning
BubbleControl with a new instance but still it did not assign the event to
BubbleControl.BubbleClick on the user control side.
Just wondering if anyone know how to do this.
Thanks
Tom
