<span style="FONT-SIZE: 10pt">就分页的技术来看，无非是分两种：一。通过存储过程来实现???? 此点，暂时不讲，因为网上文章很多，迟一下再发表我的意见。二。通过页面代码来实现??? 我之前在网上看到一个文章，说的是为DATALIST分页，用的技术是viewstate保存分页信息，然后再通过这个信息（如当前是第几页，每页多少等）来实现分页。虽然能实现功能，不过，这一点明显是多此一举，究其原因，是由于没有深入认识。NET。其实。NET本身有一个PagedDataSource，它是从GridView里分离出来的分页代码封装，可以轻松实现分页。下面，就以DATALIST作为例子，看一下，他是怎样使用的：<div style="BORDER-RIGHT: #cccccc 1px solid; PADDING-RIGHT: 5px; BORDER-TOP: #cccccc 1px solid; PADDING-LEFT: 4px; FONT-SIZE: 13px; PADDING-BOTTOM: 4px; BORDER-LEFT: #cccccc 1px solid; WIDTH: 98%; WORD-BREAK: break-all; PADDING-TOP: 4px; BORDER-BOTTOM: #cccccc 1px solid; BACKGROUND-COLOR: #eeeeee">
