How to load a page in iframe which is in a modal popup extender on button click event?

Hi i have a grid with a link button in a page(say for example: "page1"), When i click the link button, i need to load a page(say for example: "page2") by passing a querystring inside a iframe which i have set in a modal popup extender control. I can acheive 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!
