How to refresh UserControl Grid when RadAjaxManager is on MasterPage?

[Masterdom5]

Hi,

1)   I have a master page that contains the following controls:
      <telerik:RadAjaxManager id="RadAjaxManager" runat="server" EnablePageMethods="True" />
      <telerik:RadAjaxLoadingPanel id="DefaultLoadingPanel" runat="server" />

2)   My content page contains:
      <telerik:RadPanelItem Value="CourseControl" Text="Courses"><ContentTemplate>...</ContentTemplate></telerik:RadPanelItem>
      <telerik:RadAjaxManagerProxy id="CourseRadAjaxManagerProxy" runat="server">
         <AjaxSettings>
          <telerik:AjaxSetting AjaxControlID="CourseGrid">
           <UpdateControls>
            <telerik:AjaxUpdateControl ControlID="CourseGrid" LoadingPanelID="DefaultLoadingPanel" />
           </UpdateControls>
          </telerik:AjaxSetting>
         </AjaxSettings>
      </telerik:RadAjaxManagerProxy>

3)   My User Control known as CourseControl in the above RadPanelItem contains the following control:
       <UC1:CourseGrid id="CourseGridControl" runat="server">

4)   My CourseGrid user control which is a generic grid used by multiple user controls has a Javascript function to open a popup window (AddEditCourse.aspx) which helps users manage the courses.
 
The problem is when a new course is added to the database or an existing course is updated I am unable to refresh the grid so that the changes be visible to the user. In the CloseAndRebind() function located in the popup window, I use top.location.href = top.location.href. This refreshes the grid but it refreshes the entire page while I only want to refresh only the grid.

Complete Root: MasterPage->Couses.aspx->CoursesUC.ascx->CourseGrid.ascx->AddEditCourse.aspx

Can someone please point me in the right direction? I would appreciate if you could provide me some code sample.

Thank you in advance.

Hi,

You could add ajax settings programmatically for this scenario - if you are rebinding the grid firing an ajax request from the client, you need a setting where the ajax manager updates the grid. If the grid is initiating the postback , you need a setting where it updates itself. You can see how programmatic settings can be created here:
Add AjaxSettings programmatically

You can access the main ajax manager from every part of the page using its GetCurrent static method as shown here:
