I have two user controls in a page. In second user control there is a repeater control and delete button inside the repeater control. When I click on the delete button inside repeater ,it should refresh the first user control and it should render in the page. Currently if I click on delete button it goes to delete event handler and does the job but does not refresh the first user control. The first user control is empty when delete occurs.

I have attached the code below for your reference.

I would appreciate if I can get a solution and not examples as I have seen a few examples from Google and Telerik support which are not really helpful.

Main Page (where 2 user controls implemented):

<table>

    <tr>

    <td>

     <asp:Label style="float: left;" id="lblUpload" runat="server" Text="Basis of Design: ">  </asp:Label>

     </td><td>

      <!—User Control 1 à

     <fusion:ArtifactUpload  runat="server" IsMultiUploadControl="false" ID="BODUploadControl"  OnFileUploading="BODUpload_OnFileUploading" AutoAjaxify="true"    OnNeedsArtifactId="BODUpload_OnNeedsArtifactId" >

      <filefilters>

            <telerik:FileFilter Description="BOD Files (.doc, .docx, .pdf)" Extensions="doc,docx,pdf" />

        </filefilters>

     </fusion:ArtifactUpload>  

<!—User Control 2 à

    <fusion:ArtifactRepeater style=" padding:2px;" ID="BODRepeater" runat="server" OnFileDeleting="BODUpload_OnFileDeleted" />

    </td>

    </tr>

    <br />

    <tr>
