我这样写能实现分页 但是我的项目中数据是从webservice中传过来的XML组合 不能去操作数据库

这个分页的 控件 推荐给你

我觉得 还是 用分页控件 开始比较好

你自己写一个更好了
其实也没什么的

你给它绑定数据源的时候就只绑定固定的数量 这种方法不让我用

前面两个的都有个
pds.DataSource = ds.Tables["name"].DefaultView;
这个要出异常
[/Quote]
不固定就用参数不就完了。什么异常，贴出来。
下班了。。回去有时间看看。

你给它绑定数据源的时候就只绑定固定的数量，比如10条，然后放个asp.netpage分页控件，每次点击分页控件的时候就调用一个方法,在方法里面重新取一次数据并且重新绑定repeater就可以了
