DataSet ds=new DataSet();
                    ds=(DataSet)(Session["ExcelInfo"]);
                    this.DataGrid1.DataSource=ds;
                    this.DataGrid1.DataBind();
                    Response.ContentType="application nd.ms-excel";
                    Response.Charset="";
                    EnableViewState=false;
                    StringWriter rw=new StringWriter();
                    HtmlTextWriter hw=new HtmlTextWriter(rw);
                    this.DataGrid1.RenderControl(hw);
                    Response.Write(rw.ToString());
