I have Master Page and a Content page and I am trying to ajaxify content page. I am using RadAjaxManager to do that.

AS soon as I drop a RadCombobox on the content page  with AutoPostback=True and use it with the RadAjaxManager as the control that updates other controls, I get error :
 

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

As you can see my script code is inside the RadCodeBlock and I have very simple master page. Also, I have noticed that if I used and other standard ASP.NET control that causes the postback and I use it RadAjaxManager, I don't get the error mentioned above. I would appreciate if you would let me know a workaround to this problem. This is very urget and a quick response will be appreciated.

I am using RadControls for ASP.NET AJAX 2009 Q1.

Thanks,
Soor

Hello Manjeet,

From the provided code I can see you configured the RadAjaxManager setting properly and you also wrapped the client scripts in a RadCodeBlock as recommended. However I am not able to find the source of the error there.
Can you send a runnable version of the problematic page for further debugging and investigation?

Looking forward your reply,
