可以将DataTables列筛选器加载项与Gridview一起使用

本文关键字：Gridview 一起 加载项 DataTables 筛选 | 更新日期: 2023-09-27 18:23:50

我正试图在使用sql数据源的gridview表上使用DataTables列筛选器加载项，但我运气不佳。我让gridview渲染页眉和页脚，但我不能向页脚添加任何内容。

        </asp:GridView>

         </form>
</body>
</html>

这是呈现的CS

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/tbody/tfoot elements 
             GridView1.UseAccessibleHeader = true; 
             GridView1.HeaderRow.TableSection = TableRowSection.TableHeader;
             GridView1.FooterRow.TableSection = TableRowSection.TableFooter;
           }
}
        protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {
        }
}
}

这是HTML输出，有太多的网站要处理我放在粘贴框中的链接包括

可以将DataTables列筛选器加载项与Gridview一起使用

为了向页脚添加任何内容，您需要使用TemplateField控件而不是BoundField控件。看见http://www.dreamincode.net/forums/topic/222381-insert-data-using-gridview-footerrow/以获取如何执行此操作的示例。不过需要注意的是，GridView控件生成的HTML将在页脚中使用<td>元素，而不是DataTables文档所期望的<th>元素。
