Hi,


I am developing a sharepoint webpart i want to load controls asynchronously within sharepoint webpart. One of the controls I use is ASP.net AJAX RADPivotgrid.

i Achieved this by using of Partial Updatepanel Library.i followed this link to load controls asynchronously.(link:http://www.51aspx.com/CodeFile/PartialUpdatePanel,6051/Control/PanelHostPage.cs.html)

But now i click Filter icon in pivotgrid it gets a postback and filter window is not opened.

When i click filter icon i want to open the Filter window asynchronously.

Code:

private void ProcessPostBackControls(Control control)
       {
           if (control is RadComboBox)
           {
               if ((control as RadComboBox).OnClientSelectedIndexChanged.Equals("Telerik.Web.UI.Grid.ChangePageSizeComboHandler"))
               {
                   (control as RadComboBox).OnClientSelectedIndexChanged = "sppds_gridPageSizeChanged";
               }
           }
           else if (control is Button)
           {
                   if (!(((Button)control).CssClass.Equals("rgFilter")) && !(((Button)control).CssClass.Equals("rpgFilter")))
                   {
                       ((Button)control).OnClientClick = GetPostBackReference(control.ClientID.Replace('_', '$'), "null", true);
                       ((Button)control).OnClientClick += "return false;";
                   }
           }
           else if (control is ImageButton)
           {
                   ((ImageButton)control).OnClientClick = GetPostBackReference(control.ClientID.Replace('_', '$'), "null", true);
                   ((ImageButton)control).OnClientClick += "return false;";
           }

           foreach (Control child in control.Controls)
               ProcessPostBackControls(child);
       }

The above code works fine for radgrid Filtering and paging but does not work for Pivotgrid Filtering.


Am i missing anything here?
please help me to resolve this issue.
