一、说明

  aspnetpager.dll这个分页控件主要用于asp.net webform网站,现将整理代码如下

二、代码

1、首先在测试页面default.aspx页面添加引用

<%@ register assembly="aspnetpager" namespace="wuqi.webdiyer" tagprefix="webdiyer" %>

2、写一个repeater列表控件用于显示数据

<asp:repeater id="rptnews" runat="server">
  <itemtemplate>
    <li>
      <span><%# eval("time") %></span>
      <a href="newsshow.aspx?id=<%# eval("id") %>"><%# access.getstringnum( eval("name").tostring(),15) %></a>
    </li>
  </itemtemplate>
</asp:repeater>

3、添加

<webdiyer:aspnetpager id="aspnetpager1" runat="server" alwaysshow="true" custominfostyle="font-size: 12px"
    firstpagetext="首页" horizontalalign="center" inputboxstyle="width:19px" lastpagetext="尾页"
    meta:resourcekey="aspnetpager1" nextpagetext="下一页" pagesize="10" prevpagetext="上一页"
    style="font-size: 14px" width="95%" cssclass="anpager" currentpagebuttonclass="cpb"
    onpagechanging="aspnetpager1_pagechanging" showboxthreshold="10">
</webdiyer:aspnetpager>

pagesize属性是用于设置每页显示的数量

4、后台代码绑定

//测试数据源<br>private void shownews()
{
  string strsql = string.format("select * from news order by time asc");
  datatable dtbl = access.executedatatable(strsql, null);
  this.rptnews.datasource = access.getpagedatasource(aspnetpager1, aspnetpager1.currentpageindex - 1, dtbl);
  this.rptnews.databind();
}

access是测试数据库访问类,在最后的demo中提供给大家

5、分页控件点击页码事件

//分页
protected void aspnetpager1_pagechanging(object src, wuqi.webdiyer.pagechangingeventargs e)
{
  this.aspnetpager1.currentpageindex = e.newpageindex;
  shownews();
} 
 

最后奉上整页代码:

default.aspx

<%@ page language="c#" autoeventwireup="true" codefile="default.aspx.cs" inherits="default" %>
<%@ register assembly="aspnetpager" namespace="wuqi.webdiyer" tagprefix="webdiyer" %>
<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
 <meta http-equiv="content-type" content="text/html; charset=utf-8" />
 <title>asp.net分页控件</title>
 <link href="css/css.css" rel="stylesheet" type="text/css" />
 <style type="text/css">
 .aboutcontentnr{width:100%; height:auto; }
 </style>
</head>
<body>
 <form id="form1" runat="server">
 <div>
  <ul class="news">
   <asp:repeater id="rptnews" runat="server">
    <itemtemplate>
     <li><span>
      <%# eval("time") %></span><a href="newsshow.aspx?id=<%# eval("id") %>"><%# access.getstringnum( eval("name").tostring(),15) %></a></li>
    </itemtemplate>
   </asp:repeater>
  </ul>
  <div class="paginator">
   <webdiyer:aspnetpager id="aspnetpager1" runat="server" alwaysshow="true" custominfostyle="font-size: 12px"
    firstpagetext="首页" horizontalalign="center" inputboxstyle="width:19px" lastpagetext="尾页"
    meta:resourcekey="aspnetpager1" nextpagetext="下一页" pagesize="10" prevpagetext="上一页"
    style="font-size: 14px" width="95%" cssclass="anpager" currentpagebuttonclass="cpb"
    onpagechanging="aspnetpager1_pagechanging" showboxthreshold="10">
   </webdiyer:aspnetpager>
  </div>
 </div>
 </form>
</body>
</html>

default.aspx.cs

using system;
using system.collections.generic;
using system.linq;
using system.web;
using system.web.ui;
using system.web.ui.webcontrols;
using system.data;
public partial class default : system.web.ui.page
{
 protected void page_load(object sender, eventargs e)
 {
  if (!ispostback)
  {
   shownews();
  }
 }
 //测试数据源
 private void shownews()
 {
  string strsql = string.format("select * from news order by time asc");
  datatable dtbl = access.executedatatable(strsql, null);
  this.rptnews.datasource = access.getpagedatasource(aspnetpager1, aspnetpager1.currentpageindex - 1, dtbl);
  this.rptnews.databind();
 }
 //分页点击页码事件
 protected void aspnetpager1_pagechanging(object src, wuqi.webdiyer.pagechangingeventargs e)
 {
  this.aspnetpager1.currentpageindex = e.newpageindex;
  shownews();
 }
}
