  1. POasp.net page not posting back, while the button click event is still firing
    text
    copied!<p>Okay, so I have this page, which has one <code>Ajax:AsyncFileUploader</code> also some other ajax stuff like <code>ModelPopUpExtender</code> etc. The problem is the two buttons in the page, of <code>Cancel</code> and <code>Submit</code>, both of them <strong>firing up</strong> but none is posting back, while I made sure none of the fields in the page are blank. </p> <p>I know the events are firing up, because I debugged the JavaScript in <code>Firebug</code> (a single step into and continue process took more than 4 min, while I was just almost held the F10 key for stepping into, down!) </p> <p>If anyone wants code, please tell me I'd post it, but buttons are just in normal code so nothing special, that's why I am not posting the code, but in case required I can post entire page's code (which is <strong>pretty long</strong> I'd tell you, not really though, but at least just for posting purpose in here, somewhat around 200 lines). Any help anyone?</p> <p><strong>Edit: As per comment I am posting the code</strong><br> <strong>code: aspx page</strong></p> <pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %&gt;
