asp.net求一个分页的代码

用datalist绑定的数据源。代码不要太复杂本人新手。有首页、上页、下页、尾页功能及可。代码要有注释适合新手的内容！
废话，我要用dataview还要你说，你以为全世界就你一个聪明人么。

Answer 1

DataList分页的话需要后台代码
用GridView自带分页

Answer 2

翻页的话，有几种方法，最简单的是用自带的翻页功能，在就是还可以你自己写一些翻页方法，在页面调用给datalist，我用的是一个叫aspnetpager的翻页控件，你可以在网上搜搜，用法跟其他控件一样，直接拖到页面上就行了，然后就是后台代码绑定，给你一个我以前绑定的方法看看：
private void DataBinds()
{
PagedDataSource pds = new PagedDataSource();
pds.DataSource = BookManager.GetNewBooks();//写你自己的方法
pds.AllowPaging = true;
pds.CurrentPageIndex = this.AspNetPager1.CurrentPageIndex - 1;
this.AspNetPager1.RecordCount = 20;//数据总数，我这里直接写20，应该是你数据count()值

pds.PageSize = this.AspNetPager1.PageSize;

this.datalist.DataSource = pds;
this.datalist.DataBind();
}
