Repeater实现分页

首页页面的控件有如下几个

1.repeater1 repeater控件,对他进行分页

2.label1 用来显示和存储页码信息

3.label2 用来显示和存储总页码信息

4.linkButton1 首页

5.linkButton2 上一页

6.linkButton3 下一页

7.linkButton4 末页

8.DropDownlist1 实现页面跳转



DataSet ds = DataBase.news.show("3");这句中是用了一个类库中的静态方法 返回的是一个DataSet,也可以直接在代码里面读取数据库 只要ds是DataSet数据类型就行
