aspnetpager使用介绍

AspNetPager分页控件解决了分页中的很多问题,直接采用该控件进行分页处理,会将繁琐的分页工作变得简单化,

效果如下:

下面是我如何使用AspNetPager控件进行分页处理的详细代码:


1.首先到www.webdiyer.com下载最新的AspNetPager.dll,直接在vs2005中添加引用即可。


2.在页面上注册控件,引入该控件,当然,需要在页面中使用一个数据载体,我这里使用的是repeater控件。

注册分页控件代码:

<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>

3.分页控件页面代码:

<webdiyer:AspNetPager ID="AspNetPager1" runat="server" AlwaysShow="True" OnPageChanged="AspNetPager1_PageChanged"
                                        PageSize="5" ShowNavigationToolTip="True" FirstPageText="第一页" 
                                        LastPageText="最后一页" NextPageText="下一页" PrevPageText="上一页" SubmitButtonText="Go" 
                                        TextAfterPageIndexBox="页" TextBeforePageIndexBox="转到" Font-Bold="True" 
                                        Font-Italic="False" Font-Size="Small" ShowPageIndexBox="Always">
                                    </webdiyer:AspNetPager>

4.后台代码:

使用linq技术:

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Xml.Linq;

namespace ReSenGuang.news
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                initNews();
            }
        }

        private void initNews()
        {
            EntityDBDataContext dc = new EntityDBDataContext();
            int page = this.AspNetPager1.CurrentPageIndex;
            int size = this.AspNetPager1.PageSize;
            var newsList = dc.t_news.OrderByDescending(p => p.id).ToList();
            var news = newsList.Skip(size * (page - 1)).Take(size).ToList();
           
            if (news != null && news.Count > 0)
            {
                AspNetPager1.RecordCount = newsList.Count;
                newsDL.DataSource = news;
                newsDL.DataBind();

            }
            else
            {
                AspNetPager1.RecordCount = 0;
                newsDL.DataSource = null;
                newsDL.DataBind();
            }

        }

        protected void AspNetPager1_PageChanged(object sender, EventArgs e)
        {
            initNews();
        }

    }
}
