I can ache开发者_开发知识库ive this by adding this piece of code in markup

  <asp:TemplateField HeaderText="PO NUMBER" HeaderStyle-HorizontalAlign="Center" 
      ItemStyle-HorizontalAlign="Center" ItemStyle-Width="100px">
    <ItemTemplate>
      <asp:HiddenField ID="hfPOAID" runat="server" 
      Value='<%# Bind("POAtID") %>'></asp:HiddenField>
      <asp:LinkButton ID="lbtnPO" runat="server" ForeColor="Blue" 
      Text='<%# Bind("PONUM") %>' CommandName="POview" CommandArgument=
      '<%# ((GridViewRow) Container).RowIndex %>' AutoPostBack="True">
      </asp:LinkButton>
<cc1:ModalPopupExtender ID="mpeStatus" OnOkScript="__doPostBack('Ok','')"  
runat="server" TargetControlID="lbtnPO" PopupControlID="pnlPerson" DropShadow="true" 
CancelControlID="ibCancel1" >  </cc1:modalpopupextender>              
<asp:Panel ID="pnlPerson" runat="server" Style="display: none" 
 Width="900px" Height="550px" CssClass="modalPopup">
   <div style="float: right;">
      <asp:ImageButton ID="ibCancel1" runat="server" ImageUrl="~/Images/del.png" 
      Width="20px" Height="20px" /> 
   </div>
   <div>
    <table>
      <tr>
        <td align="center" style="font-size: 14px;">
          <b>View Purchase Order</b>
        </td>
     </tr>
     <tr>
        <td>
          <iframe name="FRAME1" width="800" height="500" frameborder="0" 
              src='<%#String.Format("ShowPO.aspx?Poid={0}", Eval("POAtID"))%>'>
          </iframe>
        </td>
       </tr>
     </table>
   </div>
  </asp:Panel>
  </ItemTemplate>
  <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
  <ItemStyle HorizontalAlign="Center"></ItemStyle>
  </asp:TemplateField>

And in the Code Behind page----------------

   protected void gvPOCloseRpt_OnRowCommand(object sender, GridViewCommandEventArgs e)
   {
   try
   {
     if (e.CommandName == "POview")
     {
          int index = Int32.Parse(e.CommandArgument.ToString());
          HiddenField hfPOAID = (HiddenField)gvPOCloseRpt.Rows[index].FindControl
          ("hfPOAID");
          Session["POID"] = hfPOAID.Value;
          string Script = "window.open('http://mak-erp/deverp/Purchase/poprnt.aspx')";
          System.Web.UI.ScriptManager.RegisterClientScriptBlock(this, 
          this.GetType(), "test", Script, true);
     }
   }
   catch (Exception ex)
   {
     Response.Write(ex);
   }
}

But, if there is bulk data's in grid, it take too long time to load a page, So, I need to load the page only on a click event of link button in grid?......

Can anyone help me out to do this.....

Thanks in advance...........

You can try ThickBox to pop up the page2.

And you can use url query string to pass the POID parameter.

see more information about ThickBox : https://web.archive.org/web/20120502133946/https://jquery.com/demo/thickbox/

Or you can use ajax to achieve this!

Try using jQuery modal popup referring a div which in turn contains an iframe to display the page. Like :

$('#btnOpenPopup').click(function (e) {
    $('#frmLoadPage').attr('src','your_page_url');
    $('#divContainer').modal();
    return false;
});

<div id="divContainer" class="form-control">
  <iframe id="frmLoadPage" ></iframe>
</div>
