I'm attempting to convert my pages using the ASP.Net controls to the ASP.Net Ajax controls. I have a page with a Grid and Menu, and got those converted fine, but I'm receiving errors when I try to convert the RadAjaxManager.
If I drop this code onto the page:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadGrid1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1"/>
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>
Then I get the "The Controls collection cannot be modified because the control contains code blocks" error. I'm using a master page, and there's no code inside the <head></head> tag, just a title and a link for a .css file. As soon as I remove the RadAjaxManager control, it works fine (just without ajax...).
Suggestions?

Figured it out, I had to wrap a script block containing <% %> with:
<telerik:RadCodeBlock ID="cb1" runat="server">
</telerik:RadCodeBlock>
<telerik:RadCodeBlock ID="cb1" runat="server">
</telerik:RadCodeBlock>

I wrapped my JS inside the RadCodeBlock. But I'm still getting the error. I also checked there is no scripts in <head>. What else could be wrong?

Hi Pranav,
There might be some other place or other control included in the page (a user control or some custom control for example) where the server code blocks generate the exception. Perform a global search in your project to verify that and read the following topic from the online documenation for more details:
