Answer

I was setting the targetcontrolid of the extender to a hidden button and trying to fire the Show() event in server side code. It wasn't being displayed even though the code was getting hit. I discovered that the problem was that I was hiding the hidden button using "visible = false" which doesn't render the control to the page. I changed it to "style='display:none'" and it started working. Try changing your target control to a hidden button and make sure it's getting rendered and maybe it will work.
