wow, 6 years and still active...

Paul have you found a solution to your problem? I have the same question...

I have a button whose code behind event I want fired when it's clicked on, but I don't want it to cause a postback... sounds strange (and someone illogical too, I appreciate that!), and there are possibly workarounds as well, but this is an interesting problem and I want to see if it can be resolved as is. anyone any ideas?

Paul, in case nobody's got a bright idea, you may want to take a look at:

it explains how to determine what control caused the postback and then get creative from there. But I still badly want this question answered!

thanks for yout time.
