asp.net分页是最最常用的功能，实现方式也很多，使用不同的控件有不同的分页方式。
下面分享一个我们团队内部使用了多年的一个分页控件cPage，是自己设计编写，没有冗余，简单、快速。
cPage，现在版本是3.2了，很简单的一个分页功能，可以到这里【下载】。最好是下载这个demo。
cPage是asp.net分页控件，也可以叫做分页组件，更确切的应该叫做分页模块，也或者叫做分页通用代码。
cPage，使用url传值实现分页，支持多种asp.net数据控件，如datalist、gridview、Repeater等，支持多种数据源，如SQL Server、Oracle、mysql、DB2等，说的白一点就是能够生成datatable的就可以。
支持url重写（UrlRewrite）分页，比如，常用url分页“info.aspx?p=[#p#]”，url重写“info_[#p#].html”，url中页码是通过“[#p#]”传递的，所以支持任何形式的分页，更多详细请查阅demo。
先来一张效果图：
cPage分装了dll，名称为“cPage.dll”，更重要的是要使用，所以demo很重要。下面是demo的代码:
demo使用了sqlserver2008r2数据库，IDE是vs2010。
demo分页效果图：
sql代码：
CREATE TABLE [info]( [ID] [int] IDENTITY(1,1) NOT NULL, [name] [nvarchar](50) NULL, [card] [nvarchar](50) NOT NULL, [createtime] [datetime] NULL)
