GridView排序简单实现

使用javascript操作table排序才是实用的排序，这样排序不怎么好，但是有时候可能会用来，记录一下。

前台：

代码
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="GridViewSort.aspx.cs" Inherits="GridViewSort" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">

</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:GridView ID="gdvSort" runat="server" OnSorting="gdvSort_Sorting">
        </asp:GridView>
    </div>
    </form>
</body>
</html>
