<BR> I have an ImageButton on an asp.net page. After the user click the image, I want to be able to process some data first, then postback this page. And I think this is how an ImageButton should behave. But what I saw was the Page_Load got executed before the ImageButton_OnClick handler was called. If what I saw is the correct behavior, how could I process something before the page get postback?<BR> Thanks.
