I don't want a postback to happen if no one is listening for this event (that is, in my user control if I were to just bind to SelectedIndexChanged and raise my own event, a postback will occur each time an item is changed even if the page it was hosted on didn't care about the event). I am trying to avoid this postback if it's not necessary.

Paul,

I see in the help that web controls have an Events property (inherited from Control) that will return an EventHandlerList. I don't see anything in the EventHandlerList that would tell you the number of events, but perhaps it is a place to start looking.
