    Hi ,

    I am new to using the RadSplitter. I am trying to display a Loadingpanel on a Splitter section on a button click event.

        <telerik:RadSplitBar  ID="Radsplitbar3" runat="server" CollapseMode="Forward" />
          <telerik:RadPane ID="navigationPane" runat="server" >
         </telerik:RadPane>
            </telerik:RadSplitter>

    In the code behind section
     navigationPane.ContentUrl = "ReportViewer.aspx?report=" + Query;

    So there are no controls within the splitterPane.
    When I try to do this
       <telerik:RadAjaxManager runat="server">
              <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="Button4">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="navigationPane" LoadingPanelID="LoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                </AjaxSettings>
            </telerik:RadAjaxManager>
             <telerik:RadAjaxLoadingPanel ID="LoadingPanel1" runat="server" /> it causes an exception
    "System.ArgumentException: SplitterItemsCollection must contain SplitterItem objects"
    Could you help me with a workaround for this.

    Thank you,
    Seyashi.

    Hi Sreyashi Chatterjee,

    I am afraid that the provided explanations are not detailed enough to find the reason for the problem. However, as far as I can see you want to have an external page and to display a loading animation and if so I suggest to examine the following KB article about this:

    http://www.telerik.com/support/kb/aspnet-ajax/splitter/display-a-loading-animation-while-an-external-page-is-loading-in-a-radpane.aspx

    Let me know whether the article solved the issue and how it goes.

    Sincerely yours,
