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：

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。
