       //解决导出到Excel2007乱码问题
        Response.Write("<meta http-equiv=Content-Type content=text/html;charset=GB2312>");

    #region 导出Word按钮功能实现
    protected void btnWord_Click(object sender, EventArgs e)

        GridView_BindByDate();

注：

#region 窗体标记
    //如果没有下面方法会报错，类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内（导出Excel或Word用）
    public override void VerifyRenderingInServerForm(Control control)
    {

    }
    #endregion
