Hello vivek,

The only thing I can assume without having your code is that you have missed to declare a ScriptManager before the manager is added to the page. If so, please note that script controls should be registered in the ScriptManager and this is the most probable reason for this error. Another option is that you are adding the manager in some event which is not suitable considering the page lifecycle but I cannot tell you the exact reason until I am able to see what is actually going on. Another problem could be caused by incorrect usage of AJAX.

This being said, if the problem persists, please provide code on base of which a fully runnable reproduction page could be created and I will do my best to help.

Hello, my first post so likely wrong.

You may be using the:

<asp:ScriptManager>

Instead of the:

<telerik:RadScriptManager>

Also, I find if you embed some AJAX controls in a table or other control that is made visible=false during the pre-render, this can also cause this error.

Cheers,
