以下是我目前为项目启动的代码。我正在更新新的码。我收到Gridview1不存在的错误。

        $(function () {
            $('#<%=GridView1.ClientID%>').dataTable();
    });
</script>

</body>
</html>

有什么我想念的东西。我需要能够使用某种搜索过滤结果。

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;
           }
}
    }
}

Answer 1

是的，这绝对是可能的，但我从未尝试过使用SqlDataSource。我就是这样做的：

在您的信息页中添加TextBox和Button。
在Button的{{1}}事件中，您需要阅读Click中的文字并查询您的数据库。
这是它可以分歧的地方。您可以使用旧学校TextBox（ADO.NET，SqlConnection等），也可以使用SqlCommand，这是更新的方式。你更熟悉哪种方式？我会根据你的回答量身定制答案。

Answer 2

（我认为你指的是datatables jquery插件。）

是的，这是可能的。您需要确保GridView在表格中生成thead标记，因此您需要执行以下操作：

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;
   }
}

现在你可以做到：

<script>
    $(function(){
        $('#<%=Gridview1.ClientID%>').dataTable();
    });
</script>

有没有办法在asp.net中使用Datatables来创建使用gridview创建的表？
