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(); }}
