解析asp.net的分页控件
作者：冷战
本文主要对AspNetPager.dll这个分页控件进行介绍，它主要用于asp.net webform网站。文章结尾附上实例下载，有需要的朋友可以看下
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" %>

</asp:Repeater>
</ul>
<div class="paginator">

</div>
</form>
</body>
</html>
Default.aspx.cs
using System;

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();
}
}
