后台是拼表格的形式在前台读取数据的，怎么实现分页？急啊！在线等！

[风流倜傥你水哥]

这是代码
for (int i = 0; i < dt.Rows.Count; i++)
{
returnstring += "<tr>";
returnstring += "<td width=\"50\" height=\"30\" align=\"center\"><img src=\"images/y_89.jpg\" width=\"3\" height=\"3\" /></td>";
returnstring += "<td><span class=\"STYLE21\"><a href=\"ys.aspx?id=" + dt.Rows[i]["PS_ID"] + "\">" + dt.Rows[i]["PS_Title"].ToString() + "</a></span></td>";
returnstring += "<td width=\"150\" align=\"center\"><span class=\"STYLE21\">[" + dt.Rows[i]["PS_Time"].ToString() + "]</span></td>";
returnstring += "</tr>";
returnstring += "<tr><td height=\"1\" colspan=\"3\" align=\"center\"><hr size='1' noshade='noshade' style='border: 1px #888888 dotted;' /></td></tr>";
}

很简单啊，查询的时候分页就好了。
举个例子，第一页拼出来50条数据，当点第二页的时候，
你再查第二页的数据，当然也会执行这个拼表格的方法，拼出来显示的就是第二页的数据。
页码的话，你根据表里面的总记录数，除以每页显示的数据 算出来的那个数字循环递增就好了。
你每次点下一页，重新查下一页的数据，重新拼新的页面。
不知道你明白没有 。。。
给你个分页的存储过程

)

SELECT * FROM orderlist
WHERE 
rownum between @startIndex and @endIndex   
--and ordDate>= @beginTime   and  ordDate<=  @endTime 
order by  ordDate desc ;

END

关键就是

rownum between @startIndex and @endIndex   
--and ordDate>= @beginTime   and  ordDate<=  @endTime 
order by  ordDate desc ;

每次查询 一页里面需要显示的数据

从数据库 取的时候分页
一次只取10条
