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

    I am using the RadAjaxManager, but I keep getting this error as a YSOD. I got it once before and it was because I didn't have runat set to server on my form. But now I do. Here is my code:

        <form id="form1" runat="server">
          <telerik:RadAjaxManager  ID="RadAjaxManager1" EnableAJAX="true" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">      
            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <telerik:AjaxUpdatedControl ControlID="RadGrid1" />

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    This seems correct to me. What am I missing?
