Hi,

I am creating a sharepoint 2010 visual webpart with a WebHierarchicalDataGrid bound to a sharepoint list.  I wanted to refresh the grid on a button click asynchronously without re-loading the page, hence i placed a WARP control and moved the WebHierarchicalDataGrid inside a WARP. 

ASP code.

 <igmisc:WebAsyncRefreshPanel ID="WebAsyncRefreshPanel1" runat="server"
                                    Height="402px"  Width="1600px"
                                    TriggerControlIDs="*$Button1" BorderColor="#CCFFCC"> 
                              <ig:WebHierarchicalDataGrid ID="WebHierarchicalDataGrid_PT" runat="server"

......................

       </ig:WebHierarchicalDataGrid>                               
</igmisc:WebAsyncRefreshPanel>   

code behind (vb)

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

        ' Set up data source and bind to grid
        BindGrid()

   End Sub

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
        BindGrid()
    End Sub

My problem is, the grid is shown properly on the page load (full postback), but on button click, the grid disappears from the WARP.

I am a newbie in ingragistics controls.  Please help.

Thanks

Rajesh
