发现在winform中的DataGridView居然是没有分页的，本来准备去写个但是又没那么多时间去构思就在园子里面找了一个，我把修改以后的发上来已经添加了注释，原出处为：http://www.cnblogs.com/flood/archive/2005/05/13/154527.html；非常感谢原作者；

引用示例：
this.paperControl1.Init(count, perpage);
Init是设置总长度和每页多少条，他会自动调用currentPageChanged的，但是控件放到页面上以后也要绑定currentPageChanged的绑定页面列表的事件，所以绑定页面列表的方法写成事件，直接绑定给控件的currentPageChanged，而没必要在Load里面再放一个绑定事件了，那样容易引起死循环（这一点很重要）
如果还有不明白的可以跟帖提出来，我们一起探讨一下！
