If you receive "Unable to get property 'PageRequestManager
' of undefined or null reference" error only on IE10
, and your site is working in other browser, it is most probably that the MicrosoftAjaxWebForms.js
fails to be included in the scripts for your page. This is known to be caused by bug in the browser definition files in .NET 4.0
and .NET 2.0
used by the ASP.NET
In order to fix that you can use the corresponding hot fix as follows:
For .NET 4.0
check this one: http://support.microsoft.com/kb/2600088
For .NET 2.0
for Win7 SP1/Windows Server 2008 R2 SP1, Windows Vista/Server 2008, Windows XP/Server 2003
for Win7/Windows Server 2008 R2 RTM
If, however, you are still having issues on this regard it would be better to open a support ticket and provide us with a small runnable VS example that reproduces the issue, so that we can make an investigation locally.
