解析asp.net的分页控件

编辑: admin 分类: .net 发布时间: 2022-03-10 来源:互联网

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" %>

</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【文章出处:cc防御 转载请说明出处】(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
 {
  this.AspNetPager1.CurrentPageIndex = e.NewPageIndex;
  ShowNews();
 }
}
