导出 Gridview数据到 Excel

弹框的效果还木实现。

只是简单的导出。

protected void imgExport_Click(object sender, EventArgs e)
    {
        if (this.GridView1.PageCount == 0)
        {
            Page.RegisterStartupScript(DateTime.Now.ToString(), "<script>alert('没有数据！')</script>");
        }
        else
        {
            Response.Clear();
            //设定编码格式
            Response.Charset = "UTF-8";
            //设定文件名
            Response.AddHeader("content-disposition", "attachment;filename=Neware Ip.xls");
            //设定类型
            Response.ContentType = "application/vnd.xls";
            //创建写入器
            StringWriter sw = new StringWriter();
            //创建写入流
            HtmlTextWriter htw = new HtmlTextWriter(sw);
            //写入数据
            GridView1.RenderControl(htw);
            Response.Write(sw.ToString());
            //关闭请求
            Response.End();
        }
    }
