建三个Lable控件，ID分别为lb_page,lb_count,lb_currentpage,分别表示共有多少页，共有多少条记录，当前页是多少页
建四个LinkButton控件,ID分别为lbtn_frist,lbtn_up,lbtn_down,lbtn_last,分别表示首页，上一页，下一页，尾页
建一个DropDownList控件，表于选择要跳转到的页
当然肯定要建一个datalist控件，不用设置数据源，因为在.cs代码里设置，唯一要做的就是编辑一下模板
.ASPX代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
无标题页 .CS代码如下：
