GridView導出Excel

 首先在頭部添加EnableEventValidation="false"

 

<%@ Page Language="C#" MasterPageFile="Admin.Master" AutoEventWireup="true"
 CodeBehind="S_CheckNO.aspx.cs" Inherits="" EnableEventValidation="false" Title="無標題頁" %>

 

//導出至表格
      protected void Button1_Click(object sender, EventArgs e)
      {
          Response.Clear();
          Response.Buffer = true;
          Response.Charset = "GB2312";
          Response.AppendHeader("Content-Disposition", "p_w_upload;filename=FileName.xls");
          Response.ContentEncoding = Encoding.UTF8;
          Response.ContentType = "application/vnd.xls";
          StringWriter strwrite = new StringWriter();
          HtmlTextWriter textwrite = new HtmlTextWriter(strwrite);

          GridView1.AllowPaging = false;
          GridView1.DataBind();
          GridView1.RenderControl(textwrite);
          Response.Output.Write(strwrite.ToString());
          Response.End();
          GridView1.AllowPaging = true;
          GridView1.DataBind();
      }
public override void VerifyRenderingInServerForm(Control control)         {          }
