    I'm having some issues getting an AjaxPanel to update. 

    On my content page, I have 2 user controls wrapped in an AjaxPanel: 

    <telerik:RadAjaxPanel ID="AjaxPanel1" runat="server"  OnAjaxRequest="RadAjaxPanel1_AjaxRequest"  >
       <div class="row">
               <div class="col-md-6">
                   <uc1:TView runat="server" ID="TView" />
               <div class="col-md-6">
                     <uc1:ProControl runat="server" ID="ProcView" />

    In my user control, I have a link that opens a fairly simple RadWindow via JS


    <telerik:RadWindow ID="WinPView" runat="server" Width="700px"
        Height="732px" ReloadOnShow="true"
         OnClientClose="closeWithAlert"  CssClass="" skin="Sunset"
        Behaviors="Close" Modal="True" EnableViewState="true" VisibleTitlebar="false"

    When the window is closing, I pass some data back to my content page JS asks the panel to update


    '// JS
     function invokeAjaxrequest() {
                    $find("<%= AjaxPanel1.ClientID%>").ajaxRequest();
    '// Code Behind
     Protected Sub RadAjaxPanel1_AjaxRequest(sender As Object, e As AjaxRequestEventArgs)
            End If
        End Sub


    In that JS function I ask the AjaxPanel to update. It appears to only work sometimes. Suggestions to troubleshoot this? I seem to be able to hit the breakpoint so i know the JS request to update is hitting, however the UI is not refreshing, thus for some reason the ajaxpanel is not updating the content. Ive adjusted the maxqueue size as well.

    Hi Dan,

    The presented code looks absolutely correct to me and there is no obvious reason for the issue to appear, The strange thing is that the UserControls are not updating randomly and the issue appear from time to time. Can you please inspect the server response in the browser's console and see if any errors appear when the panel fails to update?
