关于VS2005中GridView的自定义分页,单选、多选的简单应用。 图片效果:
简单示例,代码如下, fenpage.aspx的代码:

数据库中表的生成代码:
CREATE TABLE [dbo].[test01] ( [id] [decimal](18, 0) IDENTITY (1, 1) NOT NULL , [name] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL , [card] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL , [createdate] [datetime] NULL ) ON [PRIMARY] GO
ALTER TABLE [dbo].[test01] ADD CONSTRAINT [DF_test01_createdate] DEFAULT (getdate()) FOR [createdate], CONSTRAINT [PK_test01] PRIMARY KEY CLUSTERED ( [id] ) ON [PRIMARY] GO
