RadAjaxLoadingPanel not displaying on ajaxRequest

[Sean Severson]

I have a main page that contains several user controls.  One user control displays a RadWindow for entering information and then, upon close, refreshes a grid via an ajaxRequest.  The main page contains the RadWindowManager, RadAjaxManager, and the RadAjaxLoadingPanel.  I am able to add a new record and have the grid updated asynchronously,  except that the AjaxLoadingPanel is not displayed when the grid is updating.  The AjaxLoadingPanel does display when the "trigger" for the Asynchronous postback is the grid itself, however.

This is the javascript that runs OnClientClose of the RadWindow...

var radAjaxMgr = $find('<%= PageRadAjaxManager.clientID %>');
radAjaxMgr.ajaxRequestWithTarget('<%= NotesGrid.clientID %>', '');
$find('<%= PageRadAjaxManager.clientID %>').ajaxRequest('Note');

Here is the code to set the AjaxRequest handler and to register the grid with the AjaxManager.

Dim manager As RadAjaxManager = RadAjaxManager.GetCurrent(Page)
AddHandler manager.AjaxRequest, AddressOf PalNoteTaskListAjaxManager_AjaxRequest

PageRadAjaxManager.AjaxSettings.AddAjaxSetting(manager, TaskGrid, lpWait)

This is the code for the AjaxRequest handler...

Protected Sub PalNoteTaskListAjaxManager_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs)
       Select Case e.Argument
           Case "Task"
               PopulateTaskGrid(False)
           Case "CompTask"
               PopulateCompletedTaskGrid(False)
           Case "Note"
               FillNoteGrid(False)
       End Select
   End Sub

This is the AjaxLoadingPanel...

<telerik:RadAjaxLoadingPanel
    id="lpWait"
    InitialDelayTime="0"
    runat="server"
    Transparency="10"
    Height="100%" Width="100%" >
    <table Height="200px" Width="100%" >
       <tr valign="middle" >
          <td align="center">
             <img src="/SI/Images/status_anim.gif"  title="Wait" />
          </td>
       </tr>
    </table>
</telerik:RadAjaxLoadingPanel>

Thanks for your help!

Hello Sean,

Could you please try showing and hiding the LoadingPanel explicitly on the Ajax requests. Please refer to the following help topic for more information on this matter.
Let me know if this helps.

Maria Ilieva,

I will look over the help topic you provided and see if I can manually display the loading panel.  Thank you for your help.
