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) demo的页面,cPageList.aspx,代码如下:
