Ajax with Nested panels

[Rita15]

Hi,
         Can someone please help me to set up Ajax setting for the following scenario.
1) There is a RadAjax Manager in Master Page.
2) In Content page, I have the following Control structure.

<asp:Content ID="topPaneContent" ContentPlaceHolderID="Right_Content" runat="server">
 <telerik:RadAjaxPanel ID="IDRLoadingPanel" runat="server" EnableAJAX="false">

  <telerik:RadSplitter ID="IDRSplitter" runat="server" Orientation="Horizontal" Width="100%">
       <telerik:RadPane ID="IDRMainPane" runat="server">
            <asp:Button ID="UpdateBtn" runat="server" Text="Update" OnClick="UpdateBtn_OnClick"/>
            <asp:Button ID="AddBtn" runat="server" Text="Add" OnClick="AddBtn_OnClick"/>
            <asp:Button ID="DeleteBtn" runat="server" Text="Delete" OnClick="DeleteBtn_OnClick"/>
            <asp:Button ID="RefreshBtn" runat="server" Text="Refresh" OnClick="RefreshBtn_OnClick"/>

            <asp:SqlDataSource ID="dataSourceIDRs" runat="server" ConnectionString="<%$ ConnectionStrings:SQL_AppConString %>"
            SelectCommand="IDR_GET_IDR_LIST" SelectCommandType="StoredProcedure">
                <SelectParameters>
                    <asp:Parameter Name="IDRType" DefaultValue="~" />
                </SelectParameters>
            </asp:SqlDataSource>

            <telerik:RadGrid ID="grdIDR" runat="server" DataSourceID="dataSourceIDRs"
            AllowFilteringByColumn="True" AutoGenerateColumns="False" AllowPaging="True" AllowSorting="True"

                     <telerik:RadSplitBar ID="IDRDetailSplitBar" runat="server" CollapseMode="Both" />

                     <telerik:RadPane ID="IDRDetailBottomPane" runat="server">

                     </telerik:RadPane>
                 </telerik:RadSplitter>


      </telerik:RadPane>
  </telerik:RadSplitter>
 </telerik:RadAjaxPanel>
</asp:Content>

Objective:
IDRDetailRAP dynamiccally loads a form as user control. my objective is when the Update button is clicked , all the controls should get refreshed without flickering.

I tried to put all the control inside a RadajaxPanel, but it did not work.

Please help me.

Thanks!

Hello Rita,

Could you please try setting the EnableAJAX property of the RadAjaxPanel to true:

<asp:Content ID="topPaneContent" ContentPlaceHolderID="Right_Content" runat="server">
<telerik:RadAjaxPanel ID="IDRLoadingPanel" runat="server" EnableAJAX="True">
....

If this does not help to resolve the described issue, would it be possible for you to prepare and send us a simple running project, demonstrating this problem. You could open a formal support ticket from your Telerik account and attach a ZIP file there. In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.
