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();
}
}
