    Hi all,
    i have a problem with MasterPage and AjaxManager, this trivial example works with VS2008 but con VS2010 framework 4.0 reports an error and
    I can not use the RadAjaxManager with the setting in a MasterPage.
    PS) This sample is in a Help CHM: MasterPages: ajaxify and update controls in master and content page.
    With Framework 3.5 work fine (Telerik Version 2010.1.309.35  RunTime:v2.0.50727)

    Master Page:
    <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="MasterPage.master.cs" Inherits="RadControlsWebApp1.MasterPage" %> 
     
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
     
    <html xmlns="http://www.w3.org/1999/xhtml"
    <head runat="server"
        <title></title
        <asp:ContentPlaceHolder ID="head" runat="server"
        </asp:ContentPlaceHolder> 
    </head> 
    <body> 
        <form id="form1" runat="server"
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server"
            <Scripts> 
                <%--Needed for JavaScript IntelliSense in VS2010--%> 
                <%--For VS2008 replace RadScriptManager with ScriptManager--%> 
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" /> 
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" /> 
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" /> 
            </Scripts> 
        </telerik:RadScriptManager> 
        <script type="text/javascript"
            //Put your Java Script code here. 
        </script> 
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"
            <AjaxSettings> 
                <telerik:AjaxSetting AjaxControlID="btnDecrease"
                    <UpdatedControls> 
                        <telerik:AjaxUpdatedControl ControlID="TextBox1" /> 
                    </UpdatedControls> 
                </telerik:AjaxSetting> 
            </AjaxSettings> 
             
        </telerik:RadAjaxManager> 
      
        <telerik:RadSkinManager ID="RadSkinManager1" Runat="server" Skin="Office2007"
        </telerik:RadSkinManager> 
        <div> 
        <asp:LinkButton ID="btnDecrease" runat="server" OnClick="btnDecrease_Click">Decrease</asp:LinkButton> 
    <asp:TextBox ID="TextBox1" runat="server">0</asp:TextBox> 
     
            <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"
             
            </asp:ContentPlaceHolder> 
        </div> 
        </form> 
    </body> 
    </html> 

    ContentPage:
    <%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.Master" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="RadControlsWebApp1.WebForm1" %> 
    <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server"
    </asp:Content> 
    <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"
    </asp:Content> 

    This is the Javascript error:

      'get_postBackElement().id' è nullo o non è un oggetto  Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3ait-IT%3a00000000-0000-0000-0000-000000000000%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%3ait-IT%3aa491094c-5dfe-45a9-a72f-e5f5f0640d11%3a16e4e7cd%3af7645509%3a22a6274a%3aed16cbdc, Riga 1054 Carattere 1

    If I hide hte AjaxSetting it works but is obviously made the postback the entire page:
    <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="MasterPage.master.cs" Inherits="RadControlsWebApp1.MasterPage" %>

    <body> 
        <form id="form1" runat="server"

        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"
             
        </telerik:RadAjaxManager> 
      
        <telerik:RadSkinManager ID="RadSkinManager1" Runat="server" Skin="Office2007"

    Hello Aurelio,

    The problem is related to a bug in the 4.0 version of the .Net Framework which prevents RadAjaxManager from working properly in Master/Content page scenarios. To workaround it you can set ClientIDMode of the page to "AutoID". You can also read the following blog post for more details about this.

    I can also inform you that the issue in the Framework is fixed by Microsoft and RadAjaxManager will work for the final release of VS2010 and .Net 4.0 in such a scenario.

    Sincerely yours,
    Pavel
