Hello,

 I have a project that uses the RadAjaxManager all over the place and prior to the upgrade all of the controls would update just fine. Since the upgrade however none of the controls update. The only thing I get back is an error in the console when ever I do an action that should cause an Ajax update. The control bellow is one example of the many controls and pages using the RadAjaxManager 

 Masterpage.master

01.<body>
02.    <form id="form1" runat="server">
03. 
04.    <telerik:RadScriptManager ID="MasterRadScriptManager" runat="server">
05.        <Scripts>
06.            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
07.            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
08.            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
09.        </Scripts>
10.    </telerik:RadScriptManager>
11. 
12.    <telerik:RadAjaxManager ID="MasterRadAjaxManager" runat="server" EnableAJAX="true" UpdatePanelsRenderMode="Inline" EnableViewState="false">

Hi Chris,

Would you try to add the RadPane in both the UpdatedControls collection and as Ajax initiator (AjaxControlID). The approach is described in this article.

Also try to remove the EnableViewState property for RadAjaxManager and see if it makes a difference.
