一个简单的分页控件
采用Datagrid的默任的分页方式分页，后来发现对于大的数据量速度很慢，NET进程占用系统资源也很大，后来写了个分页的存储过程，每次取数据都只取当前页的，分页是分好了，但是发现翻页就没那么方便了，于是自己写了个简单的分页控件，代码如下(编译以后直接形成dll就可以用)。
sample code:
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;
namespace PageInfoControl
{
///<summary>
///WebCustomeControl1的摘要说明
///</summary>
[DefaultProperty('TotalRecord'),ToolboxData('<{0}:PageInfo runat=server></{0}:PageInfo>')]
public class PageInfo:System.Web.UI.WebControls.WebControl,IPostBackEventHandler
