导出GridView到Excel的关键之处(downmoon)

导出GridView到Excel中的关键之处
用法： ToExcel(GVStaff, TextBox1.Text);

public static void ToExcel(System.Web.UI.Controlctl, string FileName)
... {
HttpContext.Current.Response.Charset = " UTF-8 " ;
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType = " application/ms-excel " ;
HttpContext.Current.Response.AppendHeader( " Content-Disposition " , " attachment;filename= " + "" + FileName + " .xls " );
ctl.Page.EnableViewState = false ;
System.IO.StringWritertw = new System.IO.StringWriter();
HtmlTextWriterhw = new HtmlTextWriter(tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();
}

必须有下面这句！否则不会通过！

publicoverridevoidVerifyRenderingInServerForm(Controlcontrol)
... {
//ConfirmsthatanHtmlFormcontrolisrenderedfor
}
