  Jun 15, 2012 05:19 AM|LINK

  hi here is my code,

  <asp:UpdatePanel ID="UpdatePanel1" runat="server">
      <ContentTemplate >
  <div class="grid">
              
          <asp:TabContainer ID="TabGrid" runat="server" ActiveTabIndex="0"
              Height="542px" Width="1006px">
  
              <asp:TabPanel ID="TabGrid1" runat="server" HeaderText="TabPanel1">
              <ContentTemplate>
  
   <cc1:Grid ID="grid1" runat="server"  FolderStyle="premiere_blue"
          AllowAddingRecords="False"
       AutoGenerateColumns="False"  AutoPostBackOnSelect="True"
      AllowPageSizeSelection="False" AllowFiltering="True">
       
             <Columns>
                 <cc1:Column DataField="airlineimg" HeaderText="Airline" Index="0" Width ="76">
                       <TemplateSettings TemplateId="Image1" />
               </Columns>
                  
          </cc1:Grid>
              </ContentTemplate>
              </asp:TabPanel>
              
          </asp:TabContainer>
         
      </div>
       </ContentTemplate>
   </asp:UpdatePanel>

  code behind:
  
    GridView grd1 =UpdatePanel1.FindControl("TabGrid").FindControl("TabGrid1").FindControl("grid1") as GridView;
                   
  //error:null reference bcoz grd1=null
  
   grd1.DataSource = list[t - 1];
   grd1.DataBind();

  Hi,

     Dear  there is no need to UpdatePanel1.FindControl try this hope this will helps you

  //if you have use master page then use this one 

  //MainContent is content ID of contentplaceholder which is use in inner pages

  GridView grd=Master.FindControl("MainContent").FindControl("TabGrid1") as GridView;

  
  // if simply you have to use like that

  GridView  grd = Page.FindControl("TabGrid1") as GridView;

  
  Please "Mark as Answer" if this post helps.
