    Hello
    A RadDatePicker placed in the content template of a RadWindow, that is placed inside of an update panel, cause javascript "Sys.InvalidOperationException: Two components with the same id '' can't be added to the application." exception on postback.
    To get it follow repro steps below.

    Using Telerik.Web.UI.dll  2010.1.429.20 version.
    Repro steps:
    1) Create a Web Form
    2) Use this code as the form source:
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
    <!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>Untitled Page</title> 
    </head> 
    <body> 
        <form id="form1" runat="server"> 
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
        <div> 
        <telerik:RadAjaxManager runat="server" ID="ajaxManager"> 
            <AjaxSettings> 
                <telerik:AjaxSetting AjaxControlID="radWindow"> 
                    <UpdatedControls> 
                        <telerik:AjaxUpdatedControl ControlID="radWindow" /> 
                    </UpdatedControls> 
                </telerik:AjaxSetting> 
            </AjaxSettings> 
        </telerik:RadAjaxManager> 
         
        <telerik:RadWindow runat="server" ID="radWindow" VisibleOnPageLoad="true"> 
             
            <ContentTemplate> 
                <telerik:RadDatePicker AutoPostBack="true" runat="server" ID="radDatePicker"></telerik:RadDatePicker> 
            </ContentTemplate> 
         
        </telerik:RadWindow> 
        </div> 
        </form> 
    </body> 
    </html> 
    3) Open the form in a browser
    4) Pick up a date
    5)Observe javascript exception "Sys.InvalidOperationException: Two components with the same id 'radWindow_C_radDatePicker' can't be added to the application."
    Please provide a workaround as soon as possible.
