像这样的分页控件在ASP.NET中如何做呢？
我用的是datalist做了个显示数据的模板，有点像百度搜索网页后那种
想问下像这样的分页控件如何做呢？
我只能实现点前一页和后一页
不能想这样是很多个按钮
能给代码我给200分，（我只有200分）

这个你可以采用输入出到界面的办法，在界面定义 一个div id=page,然后，在后台代码中，将这种分页的ＨＴＭＬ代码输入到这个div里面

看得图片吗？这种分页可以吗?
[解决办法]
再发一次，怎么看不到图片啊
[解决办法]
晕了，还看不到

[解决办法]
做个自定义控件也行
[解决办法]
上面的已经把代码给出来
最后你自己在页面设置哈对应CSS就能获得很好的效果
