System.IO.StringWriter tw = new System.IO.StringWriter() ;
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter (tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();
如果你的 DataGrid 用了分页,它导出的是当前页的信息,也就是它导出的是 DataGrid
中显示的信息。而不是你 select 语句的全部信息。
为方便使用,写成方法如下:
public void DGToExcel(System.Web.UI.Control ctl)
{
HttpContext.Current.Response.AppendHeader("Content-
Disposition","attachment;#lename=Excel.xls");
HttpContext.Current.Response.Charset ="UTF-8";
HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType ="application/ms-excel";
ctl.Page.EnableViewState =false;
System.IO.StringWriter tw = new System.IO.StringWriter() ;
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter (tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();
}
用法:DGToExcel(datagrid1);
