    I am using Rad window which i am navigating other .aspx page on button click. There is a save functionality in the window, after closing. Calling this function in RadWindowManager.

    function closeRadWindow() {
                $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();

    the grids will be rebind. Working good with this code which mentioned below.  

    Issue : grd1 and grd2 will be in one panel1 and grd3 is in another panel2. Condition is when Panel1 only visible (Panel2 is visible false ) then getting error : 

    Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_cphContent_ctl00_cphContent_wizPageInfo_grd3Panel'. If it is being updated dynamically then it must be inside another UpdatePanel.

    Here is my code which i am using:

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
                <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                        <telerik:AjaxUpdatedControl ControlID="grd1" UpdatePanelRenderMode="Inline" />
                        <telerik:AjaxUpdatedControl ControlID="grd2" UpdatePanelRenderMode="Inline" />
                <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
                        <telerik:AjaxUpdatedControl ControlID="grd3" UpdatePanelRenderMode="Inline" />

    Code Behind:

      protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

    Note that you could not add control which is initially invisible on the page, to the RadAjaxManager settings. The initiator or the updated control should be always placed in a visible container so that the manager can locate it when necessary.
    Please review the help topic below for more information on this matter:
