UpdatePanel is not recognized in contentplace holder of ASP.NET masterpage

Hi everybody!
I am having problem with ASP.NET AJAX. I have created an AJAX enabled web site in ASP.NET. I added script manager in master page. When I added UpdatePanel in contentplace holder, i got the error message:

"Error1:Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site."

Please help. Thanks.

Hello world.
Not necessary to state but I did not get any intention from the world to my problem. However this worked me and I don' t know how. It worked fine for many times of compilation and now it repeats the same error:

Error: Could not recognize 'UpdatePanel'. It happens same fo all labels and buttons within the UpdatePanel. Please help me. This problem is boiling my head.

I am uing ASP.NET AJAX1.0. The page is the content page of a master page.
Thanks!!!

Are you using the ScriptManagerProxy?

Thanks for interest!
I am using Scriptmanager and not ScriptmanagerProxy.
But it seems now to be working. This was what I did.


Solution:
I changed all the tag Prefix in each page I used Scriptmanager in wih ajax.now this works and no more problem of unrecognizing AJAX Controls.

Thanks again!!!
