我正在尝试在预渲染期间定义 tfoot 部分和表格行。有没有办法使用 DataTables Column Filter Add-on 定义文本输入，但我无法生成 tfoot 表行。我错过了什么？

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Home
{
    public partial class Glossary : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            GridView1.PreRender += new EventHandler(GridView1_PreRender);
        }
        protected void GridView1_PreRender(object sender, EventArgs e)
        {
           if (GridView1.Rows.Count > 0)
           {
             //forces grid to render thead/th elements 
             GridView1.UseAccessibleHeader = true; 
             GridView1.HeaderRow.TableSection = TableRowSection.TableHeader;
             GridView1.FooterRow.TableSection = TableRowSection.TableFooter;
           }
}
        protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }
}
}

这是当前表单的代码。我想知道是否有什么问题。

您需要将 Gridview 的属性“ ShowFooter ”设置为True。默认设置为False

<asp:GridView ID="GridView1" runat="server" ShowFooter="True" />
