10	              Label lbl = (Label)GridView1.Rows[i].FindControl("Label1");
11	              Label lbl1 = (Label)GridView1.Rows[i].FindControl("Label2");
12	              DataRow dr = dt.NewRow();
13	              dr["empid"] = Convert.ToString(lbl.Text);

23	        Response.ContentType = "application/ms-excel";
24	        Response.AddHeader("content-disposition", string.Format("attachment;filename={0}.xls", "selectedrows"));
25	        Response.Charset = "";
26	        System.IO.StringWriter stringwriter = new StringWriter();
27	        HtmlTextWriter htmlwriter = new HtmlTextWriter(stringwriter);
28	        gd.RenderControl(htmlwriter);
29	        Response.Write(stringwriter.ToString());
30	        Response.End();
