c#中，查询之后的数据是多页显示，当点击第二页之后数据就回到了原始数据
下面是分页显示的代码//分页显示

//绑定数据
} --------------------编程问答--------------------
LZ这代码乱的,其实你可以把绑定数据放进一个方法,GridView1_PageIndexChanging事件再调用就行了 --------------------编程问答-------------------- 你的分页序号，是不是没有用一些类似ViewState的东西来记录和维持？分页的控件是否指定了样式和触发了事件？ --------------------编程问答-------------------- 重复代码太多 相同的可以提取出来 --------------------编程问答-------------------- 天啊。。。。你这代码看着难道不蛋疼吗 --------------------编程问答-------------------- 为什么这样写 啊，感觉很冗余啊 --------------------编程问答-------------------- 数据库绑定的问题，你分页部分的绑定肯定和你初始绑定不一致。 --------------------编程问答-------------------- 第一次看见这么 做分页的，
1.用 GridView 的自己的分页 功能，直接 e.NewPageIndex 就OK
2.用SQL 的Row_Number 来 对页码查询 数据。
补充：.NET技术 , ASP.NET
