copied!<p>This is an interesting way of skinning the cat. You are not asking "What did I do wrong", but "what are the likely things that I could have done wrong".</p> <p>Interesting, because I think it shows that you want to figure it our on your own, but also because I am having a hard time coming up with suggestions, without any kind of a hint. There is an almost unlimited number of possibilities.</p> <p>If the form posts back, the event fires. I think this is synonmous. If you don't see an event handler being invoked, maybe you are looking at the wrong place.</p> <p>I find this method useful in such situations. I call it from page_load, and it shows me details about what caused the event to fire, before event handlers are invoked.</p> <pre><code> /// <summary> /// Find which control caused the post back /// </summary> /// <param name="page"></param> /// <returns></returns> public static System.Web.UI.Control GetPostBackControl(System.Web.UI.Page page) { Control control = null; string ctrlname = page.Request.Params["__EVENTTARGET"]; if (ctrlname != null && ctrlname != String.Empty) { control = page.FindControl(ctrlname); } // if __EVENTTARGET is null, the control is a button type and we need to // iterate over the form collection to find it else { string ctrlStr = String.Empty; Control c = null; foreach (string ctl in page.Request.Form) { // handle ImageButton controls ... if (ctl.EndsWith(".x") || ctl.EndsWith(".y")) { ctrlStr = ctl.Substring(0, ctl.Length - 2); c = page.FindControl(ctrlStr); } else { c = page.FindControl(ctl); } if (c is System.Web.UI.WebControls.Button || c is System.Web.UI.WebControls.ImageButton) { control = c; break; } } } return control; } </code></pre>
