I have a Master Page with a RadAjaxManager. Then I have an ASPX Content Page with a RadAjaxManagerProxy. This page has a Panel control that contains a User Control. The User Control also has a RadAjaxManagerProxy.

I have the Panel on the aspx page as an updated control in the RadAjaxManagerProxy for a Button.

What happens is any updates in the ASCX Control cause the Updated Controls in its RadAjaxManagerProxy to disappear.

I have reproduced this with Firefox 3 and IE8.

Master Page:

    
            <%@ Master Language="C#" AutoEventWireup="true" CodeFile="123.master.cs" Inherits="_123" %> 
        
            <!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"> 
        
                        <asp:ScriptManager ID="scriptmanager1" runat="server" /> 
        
                  <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">

                  <telerik:RadAjaxManager ID="AjaxManager1" runat="server" UpdatePanelsRenderMode="Inline"> 
        
                  </telerik:RadAjaxManager> 
        
                </form>
