连接的数据库无法翻页，请各位大虾帮帮，
--------------------编程问答-------------------- 索引问题 建议用aspnetpager --------------------编程问答-------------------- lz一个分页功能没必要那么复杂。。。。。。。。。用aspnetpager吧
/// <summary>
/// 取得总数
/// </summary>
/// <returns></returns>
public string getTotal()
{

sb.Append("select count(*) total from Test");
DataTable dt = DBHelper.ExecuteDt(sb.ToString());
return dt.Rows[0][0].ToString();
}

sb.Append("ID not in (select top " + pageNum * currentPage + " ID from Test)");

--------------------编程问答-------------------- datagrid本身就有自带分页功能的啊，出现这样的错误，一般都是你的分页逻辑上出了问题，你仔细调试下应该就能找出问题了 --------------------编程问答-------------------- 眼花了... --------------------编程问答-------------------- 为什么要这样搞额。。用aspbagedatasoure --------------------编程问答-------------------- 控件自带翻页功能，或是手写代码记录翻页的页数咯。把代码写在控件触发事件里哦。 --------------------编程问答-------------------- 帮顶啊 曾经也遇到过这种情况啊 --------------------编程问答-------------------- 自己写一个分页控件！！！ --------------------编程问答-------------------- 加入判断 if (myGrid.CurrentPageIndex > 0) --------------------编程问答-------------------- 是的，要加个判断，你的那个-- 当然超出索引界限啊
建议哈 LZ写代码能规范点不 看得眼花！ --------------------编程问答-------------------- 断点，然后看你的页数设置是不是有问题 --------------------编程问答-------------------- LZ 分页 有点复杂哦!
补充：.NET技术 , ASP.NET
