搜索结果之后，这个翻页该怎么使用呢？他没有这个搜索条件了啊

[沧海小鱼]

谁有的帮忙贴个

[handicapped]

没有带搜索的翻页类，搜索只是对数据集进行搜索和翻页没关系，翻页只是对数据集的一种浏览方式

[沧海小鱼]

这只是一个翻页类，那我简化下问题 谁有能带搜索结果的翻页类

搜索之后的翻页

[dh20156]

需要将搜索关键词一起传递过去！

[沧海小鱼]

怎么写成类呢？

[郭大侠_]

这么长，怎么看啊

[风声3]

如果你的搜索条件是通过QueryString/Get传递的，我写的这个分页类分页链接可以自动保留QueryString使翻页不丢失搜索条件。关于这一点的代码其实很简单。

分页类见：

沉的真快

[沧海小鱼]

分页里多加个传递参数就解决了
