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();

        }

    }
