GridView 数据导出方法二

前台代码:

<asp:GridView ID="GView1" runat="server" Height="10px" Width="749px"></asp:GridView>    

在这里我们使用的是GridView数据控件

 

<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">　数据导出</asp:LinkButton><br />

通过一个链接按钮触发事件执行

后台代码:

protected void LinkButton1_Click(object sender, EventArgs e)

{

     Export_To_Excel(this,GView1);   //自定义函数,如下,函数参数是对应控件的ID号GView1

}

//该方法就是上面触发的事件

 

public void Export_To_Excel(Page page, GridView gview)

    {

        string strName = DateTime.Now.ToString("yyyy-MM-dd") + "-" + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString();

        page.Response.Clear();

        page.Response.Buffer = true;

        page.Response.Charset = "utf-8";

        page.Response.AppendHeader("Content-Disposition", "attachment;filename=" + strName + ".xls");

        page.Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");//设置输出流为简体中文

        page.Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。

        page.Response.Write("<meta http-equiv=Content-Type content=\"text/html; charset=utf-8\">");

        page.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);

        gview.AllowPaging = false;

        if (gview != null) //

        {

            gview.RenderControl(oHtmlTextWriter);//将服务器控件的内容输出

        }

        page.Response.Write(oStringWriter.ToString());

        page.Response.End();

    }

//该函数是核心函数

public override void VerifyRenderingInServerForm(Control control)

{

    //base.VerifyRenderingInServerForm(control);

}

//这个函数必须有,并且是空实现
