View Full Version : Javascript failing on Windows 7

12-19-2011, 08:30 PM
Hi - I have an ASP.Net 4.0 solution that runs fine on a Windows 2008 server. However, I've just been given a new Windows 7 64-bit machine to use as my development machine and I'm having a problem with one of my aspx pages. This page has some javascript on it, which runs fine, but then it gets to the following code:

<script type="text/javascript">
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;

This not code that I've written; it's code that's generated client-side that I see as I'm debugging my app in Visual Studio 2010 (trying to figure out what the $^#$ is going on). At any rate, once this code completes, the app does nothing. The debugger should take me to some server-side code, but it doesn't. It just sits there. The result is that the page doesn't do what it's supposed to do (no inserts to databases, no success messages, no nothing).

As I said, this problem is restricted to my W7 64-bit machine; it runs fine on W2008. Other pages with javascript in the same solution work fine on my W7 machine. I found a post (http://dopostback.net/index.php/net-framework-4-0-update-panel-problems/) that discusses a similar issue within an UpdatePanel, but I'm not using UpdatePanel. My page does have hidden controls on it, but so do other pages that work just fine. Does anyone know what could be causing this?
