C#:GridView导出Excel,以及runat=server错误处理方法
例如,你有个按钮需要点击它就会把当前显示导出Excel,按钮例子如下
<asp:LinkButton ID="LinkToExcel" runat="server" OnClick="LinkToExcel_Click">导出报表</asp:LinkButton>
双击按钮就会在语句中生成按钮方法,本例中就是红色字体部分,
然后在后台把如下代码复制进去
protected void LinkToExcel_Click(object sender, EventArgs e)
{ string style = @"<style> .text { } </script> "; Response.Clear(); Response.Buffer = true; Response.Charset = "GB2312"; //请勿删除此行,否则会出现乱码 Response.AppendHeader("Content-Disposition", "attachment; filename =NewFileName.xls"); Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); //设置输出流为简体中文 Response.ContentType = "application/ms-excel"; //设置输出文件类型为excel文件 this.EnableViewState = false; System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true); System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad); System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter); this.GridView1.RenderControl(oHtmlTextWriter); Response.Write(style); Response.Write(oStringWriter.ToString()); Response.End(); }//以下的代码务必要加在上面一段后面,
public override void VerifyRenderingInServerForm(Control control)
{ // 覆盖VerifyRenderingInServerForm方法,非常重要,否则系统会报错 //base.VerifyRenderingInServerForm(control); }//否则会出现错误:
//Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server.
