asp.net分頁是最最經常使用的功能，實現方式也不少，使用不一樣的控件有不一樣的分頁方式。javascript

下面分享一個咱們團隊內部使用了多年的一個分頁控件cPage，是本身設計編寫，沒有冗餘，簡單、快速。css

cPage，如今版本是3.2了，很簡單的一個分頁功能，能夠到這裏【下載】。最好是下載這個demo。html

cPage是asp.net分頁控件，也能夠叫作分頁組件，更確切的應該叫作分頁模塊，也或者叫作分頁通用代碼。java

cPage，使用url傳值實現分頁，支持多種asp.net數據控件，如datalist、gridview、Repeater等，支持多種數據源，如SQL Server、Oracle、mysql、DB2等，說的白一點就是可以生成datatable的就能夠。mysql

支持url重寫（UrlRewrite）分頁，好比，經常使用url分頁「info.aspx?p=[#p#]」，url重寫「info_[#p#].html」，url中頁碼是經過「[#p#]」傳遞的，因此支持任何形式的分頁，更多詳細請查閱demo。sql

先來一張效果圖：數據庫

cPage分裝了dll，名稱爲「cPage.dll」，更重要的是要使用，因此demo很重要。下面是demo的代碼:asp.net

demo使用了sqlserver2008r2數據庫，IDE是vs2010。sqlserver

demo分頁效果圖：this

sql代碼：

CREATE TABLE [info](
	[ID] [int] IDENTITY(1,1) NOT NULL,
	[name] [nvarchar](50) NULL,
	[card] [nvarchar](50) NOT NULL,
	[createtime] [datetime] NULL)

demo的頁面，cPageList.aspx，代碼以下：
