Loading panel wont show/ajax not working

[Ron]

I'm not sure if the loading panel is not showing because the ajax manager is not working or vice versa. But I do know the loading panel is not showing and it appears that the page is still performing a postback by the looks of the browser. Can you help? Here's my code

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                       <AjaxSettings>
                           <telerik:AjaxSetting AjaxControlID="grdActivity">
                               <UpdatedControls>
                                   <telerik:AjaxUpdatedControl ControlID="grdActivity" LoadingPanelID="RadAjaxLoadingPanel1" />
                               </UpdatedControls>
                           </telerik:AjaxSetting>
                       </AjaxSettings>
                   </telerik:RadAjaxManager>
                   <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
                   </telerik:RadAjaxLoadingPanel>
                  <div id="RecentActivityContent" class="QuickViewContent">
                     <telerik:RadGrid runat="server" ID="grdActivity" DataSourceID="objActivity" Width="360px"
                      GridLines="Horizontal" Skin="Sunset" ShowHeader="false" >
                      <HeaderStyle CssClass="HistoryGridHeader" />

                                           HeaderValueSeparator=" from date: " />
                                   </SelectFields>
                                   <GroupByFields>
                                       <telerik:GridGroupByField FieldName="Date" SortOrder="Descending" >
                                       </telerik:GridGroupByField>
                                   </GroupByFields>
                               </telerik:GridGroupByExpression>

                                       <asp:Label runat="server" id="lblMessage" Text='<%# Eval("Message") %>' />
                                   </ItemTemplate>
                               </telerik:GridTemplateColumn>
                           </Columns>

                           <Selecting AllowRowSelect="True"></Selecting>
                           <Resizing AllowRowResize="True" AllowColumnResize="True" EnableRealTimeResize="True"
                           ResizeGridOnColumnResize="False"></Resizing>
           </ClientSettings>
                   </telerik:RadGrid>

Thanks,
Ron.

Hello Ron,

The provided markup and Ajax settings looks correct and the radGrid should perform ajax requests instead of regular postback in this case.
Could you please set Skin property for the RadAjaxLoadingPanel and verify if this makes a difference.

I made the change to include the skin but I'm getting the same results.
