Spent about 3 hours trying to figure this error out. I am converting an existing .NET 2.0 website to .NET 3.5 w/ Prometheus. After the conversion, I keep getting a javascript error: "Sys.WebForms.PageRequestManager is null" when loading a page with RadAjaxManager. This was caused by my web.config having the line:
| <xhtmlConformance mode="Legacy"/> |
The website was originally .NET 1.0 and when converting from VS2003 to VS2005, that line is automatically injected into the web.config. By removing it, ASP.NET AJAX will work fine. Just thought I let people know in case they run into the same issue.

Thank you for posting this!
I was having a ton of trouble getting the AJAX functionality to work. I was getting a lot of page errors and very strange AJAX behavior.
I would suggest Telerik should add a note about this in the General Troubleshooting section of the documentation for the RadAjax control section.
Thanks again. If I could give you Telerik points I'd give you a bunch :-)

Hello Farhad,
Have you removed the xhtmlConformance tag from your web.config file as discussed down in this thread? Additionally, note that the latest version of RadControls for ASP.NET AJAX is Q2 2008 SP1 (2008.2.826) and you can upgrade to it following the instructions from this KB article.

hi Stephen
To begin with, I did not find any xhtmlConformance tag in my web.config file.
I cannot install new telerik version on all our servers just like that.
I need to find a fix for this version that I am using..

Hi Farhad,
The issue discussed in this thread is due to the xhtmlConformance tag in the web.config file. If the reason for the erratic behavior in your case is different, verify that your web site is AJAX-enabled and has the proper configuration settings added. You may also refer to the following article from the documentation concerning troubleshooting techniques.
