I have developed a really simple custom control. I am inheriting from the
ImageButton. I basically added a property and then add a couple of
attributes during the OnPreRender sub. It appears that my control is not
firing the click event (or at least my "client" page isn't picking it
up). In my code-behind of my aspx page, I do have Handles .... after my
sub that is suppose to handle the click event. I added just a plain
imagebutton to my page to test and that worked. Any ideas on this?

Thanks,
Jonathan

You can try
http://samples.gotdotnet.com/quickstart/aspplus/

and the select "Authoring Custom Controls" from the left.

I'm not sure about your specific problem , but I had a composite control
wher I had to "expose" one of the events from a subordinate control and
they had great info
(example Composition3.aspx
http://samples.gotdotnet.com/quickstart/util/srcview.aspx?path=/quickstart/aspplus/samples/webforms/ctrlauth/composition/Composition3.src
(warning, link may wrap))

Powerful stuff, but tricky to get started.

Hey thanks for the information. It seems if they really concentrate on
composite controls. I actually started out using a composite control.
I went back and it is now firing the events after fixing it using the tips
in those documents. The main reason I switched is that the composite control
seems to output really early in the execution cycle. I was trying to
change an ImageURL
in the click event which the ImageButton (in the compsite control)
used. Well I could never get
that to work by changing the imageurl in code. So I decided I would create
a new control that
just inherited from ImageButton. Well it now doesn't fire the click
event. If I try to put my own click event
in, it says the Imagebutton already has one (of course). Any ideas why
this is the case?

I hope I made sense in there. If I didn't, I'll try again. :)

Thanks,
Jonathan

I think maybe it would help to see some sample code. Would it be possible?
