效果如下
首页  上一页  1 2 3  下一页  尾页
这个代码有问题   但我找不到是那里的错误  点击2时还正常   点击3或1时没效果   希望看到的高人能给予指点

类里的代码
public static int  yi1, er1, san1,yi2, er2,san2,count,pageintex;

我晕你哦

这种不是大错啊  自己认真找一下噻

要习惯于 打断点  监视  等方法来查找错误

这样你也或获得不少好处的嘛

断点打不出来  代码怎么会不运行哪?

我晕  怎么可能的哦  打的断点要打到相应的位置噻
打到if (e.Item.ItemType == ListItemType.Header) 这上面

断点没反应是不是没运行代码啊

我晕 你是怎么运行的哦！？？

按F5运行

你是不是在页面那点点击右键运行的嘛！！那样是不能打到断点的噻

要按F5运行 或是点击上面那个绿色的箭头符号也可以

晕你的哦

还有 顺便说一下  在运行状态是不可以编辑代码的  只有关闭了这个运行转台才能编辑代码

首先这个 效果我以前作过 已经实现了

在思路上 我和你不同

1. 在数据库中 用一个表
    create table id
    (
      id int not null
    )
    循环存储 你要显示 分页的总页数

2.  再用一个DataList  把这这个表的 id 绑定到 要分页的 DataList 的下面
    注意: 在绑定时 你的SQL 语句要写成 每次查询你想要的数目 比如 10条
    1 2 3 4 5 6 7 8 9 10

3.  然后点击 下面的数字 把它传给你上面 用于控制分页 的Label; 我想 你有这个思路
    应该 能写的出来了啊!

如果ID为自增长的话  哪么你删除一条数据  比如说 1、2、3、4、
现在我吧3删除表，哪么这里就会缺省了！！
所以绑直接ID不可用

可以数总数 然后把这个总数遍历成1、2、3、....然后将ID存到它对应的其它属性上可以考虑这样写一下
