分页是Web应用程序中最常用到的功能之一，在ASP.NET中，虽然自带了一个可以分页的DataGrid（asp.net 1.1）和GridView（asp.net 2.0）控件，但其分页功能并不尽如人意，如可定制性差、无法通过Url实现分页功能等(Paging is one of the most commonly used functions in Web applications. In ASP.NET, you have a pagination DataGrid (asp.net 1.1) and GridView (asp.net 2) controls, but their paging functions are not satisfactory, such as poor customizable, unable to implement paging functions through Url, etc.)
