We came across a weird problem a few weeks ago where we were using an UpdatePanel through ASP.NET AJAX (.Net Framework 3.5 SP1) with an asp:dropdownlist on that page. When the update panel did a post back using ajax the drop down lists stopped working. You could click on the select list but they would not drop down with any options. This only happened in Firefox 3, no other FF version or Internet Explorer.
Through ages of google searching we found a work around online, adding a window.setTimeout() around the alert box, eg:
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "validationAlert", "window.setTimeout(\"alert('Just testing')\", 0);", true);
Hope this saves some other people time and heart ache.
It worked, but if a didn’t want a message? How I do?
The alert was just an example, you can replace alert(‘Just testing’) with any JavaScript code you want to run.
I tried with another JS code, and it didn’t worked!
Hi Pedro,
