selectedindexchanged and user controls

[Brent Burkart]

Has anyone experienced any problems with their selectedindexchanged not
firing when there are user controls present on the page? I have 4 controls
on a page and only once I remove all 4 does my dropdownbox
selectedindexchanged work.

Any ideas?

Hi Brent,

That sounds really weird. It would help if you could reduce the non-working
sample to minimum size and post it for all to see what may be wrong.

Thanks, here is the code behind my aspx and the user control. All of my user
controls are pretty much the same. They are just navigational links.
