event bubbling

[Tom Gao]

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.

I think I need to do something like BubbleControl = (BubbleControl)
Page.LoadControl("BubbleControl"); but then I tried this and it still didn't
work..

Just wondering if anyone know how to do this.

Thanks
Tom
