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(); } }
