Menu
I've been having this problem for quite a while now and tried various solutions, Editing the Webconfig with various tags.
Im using Updatepanels, timers and AJAX on my webpage.(can it be AJAX that throws the error?)
I really dont know how to define the problem, becuase i really dont know where to trace it.
I've placed a onload on the body in the masterpage (dont know if thats right) Heres some markup code and my Javascript code that i think throws the error.
MASTERPAGE:

JAVASCRIPT CODE:
if (window.addEventListener) window.addEventListener("load", load(), true);
else window.onload = load();
function load() {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}
function EndRequestHandler(sender, args) {
// NOT IMPORTANT
}

I just solved the problem. I think. I knew the function was run before the DOM was build.
So i just did this
$(document).ready(function () {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
});
One problem yet presists. When i clicking on the Imagebutton btnAdd The console says:
Uncaught ReferenceError: btnAddQuestion_Click is not defined
onclick
this directs me to my code line where this ImageButton is written.
Internet Explorer doesn't like this at all. but other browsers just proceed like it was nothing, even if the error message appears in the Dev-Console.
The Button functionality works to. the only problem is the error.
EDIT: This is now Solved. i was using "OnClientClick". on the ImageButtons. I changed it to OnClick and that solved this issue. I dont know the difference between theese two, but im happy as long as it works.

In my case I found that the culprit was caused by missing the call to MyBase.OnPreRenderComplete(e) in the overridden version of the function/method OnPreRenderComplete.
By including the call to MyBase.OnPreRenderComplete(e) everything works nicely. If the call to MyBase.OnPreRenderComplete(e) is missing then the error "Uncaught ReferenceError: Sys is not defined" is received and many things don't work properly.
Protected Overrides Sub OnPreRenderComplete(ByVal e As EventArgs) 'MyBase.OnPreRenderComplete(e) ... End Sub
