Error: 'Sys.WebForms.PageRequestManager' is null or not an object
What are all the possible ways of getting this error? And I am not able to select any row in the RADGrid, not able open combobox.

Hi Medac,
I read in a forum that the error means, the client object of the ScriptManager is missing and for some reason it is not created on the client. Make sure that you have added ScriptManager before any other controls on the page.
Also checkout the following forum links which discusses on similar topic:
FormDecorator Causes "'Sys.WebForms.PageRequestManager' is null or not an object" error
System.WebForms.PageRequestManager is null or not an object
Thanks,
Princy.

in web.config update panel will not work. In recent release of telerik has this issue been fixed?
Or how to go about this issue?

Hi Medac,
Could you please confirm that EnablePartialRendering property of the ScriptManager is set to true?
Also, can you send us your web.config file for further investigation. Providing any additional information on your case might help us get to the source of the problem.
