VC# ASP.NET GridView1数据导出
前台:
NEW一个html的按钮
后台:
web.config数据库连接配置
<connectionStrings>
<add name="gft_esp" connectionString="Data Source=192.168.0.113;Initial Catalog=gft_esp_rd;Persist Security Info=True;User ID=sa;Password=sql2k5"/>
<connectionStrings>
//数据绑定 涵数
public static DataSet Query(string SQLString)
{
using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["gft_esp"].ConnectionString))
{
DataSet ds = new DataSet();
try
{
connection.Open();
SqlDataAdapter command = new SqlDataAdapter(SQLString, connection);
command.Fill(ds, "ds");
}
catch (System.Data.SqlClient.SqlException ex)
{
throw new Exception(ex.Message);
}
return ds;
}
}
//导出事件
protected void Button1_Click(object sender, EventArgs e)
{
GridView1.AllowPaging = false;
//撤销分页后绑定所有数据
string sel = TextBox1.Text.ToString().Trim();
string sql = "SELECT * FROM [sysuser] where [User_id] like '%" + sel + "%'or [Role_id] like '%" + sel + "%'or
[Chi_Name] like '%" + sel + "%'or[Eng_Name] like '%" + sel + "%'or [Company_code] like '%" + sel + "%'or [Dept_ID] like '%" + sel + "%'or
[Phone] like '%" + sel + "%'or [E-Mail] like '%" + sel + "%'";
GridView1.DataSource = Query(sql);
GridView1.DataBind();
//导出到Excel
GridViewToExcel(GridView1);
//导出后恢复分页
GridView1.AllowPaging = true;
//重新绑定
GridView1.DataSource = Query(sql);
GridView1.DataBind();
}
//重载 VerifyRenderingInServerForm方法防止导出XLS出错误
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
//导出EXCEL
protected void GridViewToExcel(GridView gv)
{
string style = @"<style> .text { mso-number-format:\@; } </script> ";
Response.ClearContent();
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
Response.Write(style);
Response.Write(sw.ToString());
Response.End();
}
添加命名空间:
using System.IO;
在页面加入 EnableEventValidation = "false"如下
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="goods_tab.aspx.cs" Inherits="goods_tab"EnableEventValidation = "false"
Culture="zh-cn" UICulture="zh-CHT" %>
在ASP.NET中应用Response.ContentType="类型名";来断定输出格局
