<td>
     <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
</td>
<td>
   &nbsp;</td>
<td>
 &nbsp;</td>
</tr>
  <tr>
    <td>
     <asp:UpdateProgress ID="updProgress"
        AssociatedUpdatePanelID="UpdatePanel1"
        runat="server" oninit="updProgress_Init" onprerender="updProgress_PreRender">
            <ProgressTemplate>            
               <span style="color:green; font-style:italic;">Loading, please wait...</span>            
            </ProgressTemplate>
        </asp:UpdateProgress>

                Text="LoadReport" Width="176px"  ClientIDMode="Static" OnClientClick="return clickOnLoadReport();" />
                </div>
                           <asp:GridView ID="GridView1" runat="server" Height="170px" 
                    onselectedindexchanged="GridView1_SelectedIndexChanged" Width="438px">
                 </asp:GridView>
                        </ContentTemplate>

                        </Triggers>
                        </asp:UpdatePanel>

                    <td>
