GridView无代码分页排序
GridView选中，编辑，取消，删除
GridView正反双向排序
GridView和下拉菜单DropDownList结合
1.GridView无代码分页排序：
效果图：
<IMG alt="" src="http://www.vs2005.com/DownloadPictures/200708/2007080908241456.gif">
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：

78 GridView1.DataBind();
79 sqlcon.Close();

前台主要代码：

2 ForeColor="#333333" GridLines="None" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

5 <Columns>

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。
