如果你在GridView控件上设置 AllowPaging="true" or AllowSorting="true" 而没有使用使用数据源控件 DataSource (i.e. SqlDataSource, ObjectDataSource),运行则会出现下列错误：
当你在GridView控件上单击下一页时：
The GridView 'GridViewID' fired event PageIndexChanging which wasn't handled.
当你点击排序时，则回出现：
The GridView 'GridViewID' fired event Sorting which wasn't handled.
如果你没有设置GridView的DataSourceID 的属性，你必须添加一个操作才可以排序及分页。。
点这里查看下面的例子
