Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition","attachment;filename=g.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter ht = new HtmlTextWriter(sw);
gvDisplay.AllowPaging = false;
gvDisplay.DataBind();
gvDisplay.RenderControl(ht);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();

Hi,
I Write this above Code
but following error
[System.Threading.ThreadAbortException] = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}
then
I deleted a Line of Code "Response.End();"
And
Added HttpContext.Current.ApplicationInstance.CompleteRequest();
It is Passed without error but it is not working

Where the gridview located within the Update Panel or Outside the Update Panel ?

If within the Update Panel You need to add Trigger...
like

<asp:UpdatePanel ID="GridView1" runat="server" >

//gridview details


<Triggers>
//Button Id (means ExportBtn)
<asp:PostBackTrigger ControlID="ButtonId" />
</Triggers>
