GridView绝技分页排序，选中，编辑，取消，删除，双向排序，下拉菜单DropDownList结合

1.GridView无代码分页排序：

效果图：

1.AllowSorting设为True，aspx代码中是AllowSorting="True"；
2.默认1页10条，如果要修改每页条数，修改PageSize即可，在aspx代码中是PageSize="12"。
3.默认的是单向排序的，右击GridView弹出“属性”，选择AllowSorting为True即可。

2.GridView选中，编辑，取消，删除：

效果图：

 

 

后台代码：
你可以使用sqlhelper,本文没用。代码如下：

1using System;
 2using System.Data;

前台主要代码：

 

1<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4"
 2    ForeColor="#333333" GridLines="None" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
 3    OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit">
 4    <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
 5    <Columns>
 6        <asp:BoundField DataField="身份证号码" HeaderText="用户ID" ReadOnly="True" />
 7        <asp:BoundField DataField="姓名" HeaderText="用户姓名" />
 8        <asp:BoundField DataField="员工性别" HeaderText="性别" />
 9        <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
10        <asp:CommandField HeaderText="选择" ShowSelectButton="True" />
11        <asp:CommandField HeaderText="编辑" ShowEditButton="True" />
12        <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
13    </Columns>
14    <RowStyle ForeColor="#000066" />
15    <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
16    <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
17    <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
18</asp:GridView>

 

3.GridView正反双向排序：
效果图：点姓名各2次的排序，点其他也一样可以。
