Hi

I am writing a functionality to export a file as...cs file
---------=-

Response.Buffer = true;
 Response.ContentType = "application/vnd.ms-excel";
Response.ContentEncoding = System.Text.Encoding.Default;
Response.Charset = "";
Response.AddHeader("content disposition", "attachment;filename=RSG_Report_" + (string)Session["man"] + ".xls");
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
 System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
                oHtmlTextWriter.Write("<br>");
                oHtmlTextWriter.Write("<B>" + Label7.Text + " : ") ;                  oHtmlTextWriter.Write(Label12.Text);
                oHtmlTextWriter.Write("<br>");
                Response.Write(oStringWriter.ToString());
                Response.End();
