Using the Telerik example, I tried to get the grid to show Master / Detail data. The master data binds fine, but the detail data doesn't show up at all.

    
            <body> 
        
                <form id="form1" runat="server">  
        
                <telerik:RadScriptManager runat="server" OutputCompression="AutoDetect">  
        
                </telerik:RadScriptManager> 
        
                <div> 
        
                    <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" Height="200px"   
        
                        Width="100%">  
        
                <asp:Button ID="ParseButton" runat="server" Text="Parse" /><br />

                        TextMode="MultiLine" Width="100%"></asp:TextBox>
