发一个仿博客园的分页控件

与其讲是分页控件不如说是一个分页类。

在网上搜集的CSS样式一共24中经典样式供大家选择。

1.digg
2.yahoo
3.yahoo2
4.meneame
5.flickr
6.sabrosus
7.scott
8.quotes
9.black
10.black2
11.black-red
12.grayr
13.yellow
14.jogger
15.starcraft2
16.tres
17.megas512
18.technorati
19.youtube
20.msdn
21.badoo
22.manu
23.green-black
24.viciao

在demo 中有css 文件

在使用页面中引入即可

看一下分页效果。

和博客园的分页效果几乎一致

使用方法

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.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using Tension.Web.Controls;
using Tension.Extension;
 
namespace PagingBarDemo
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string pageIndex = Request.QueryString["pageIndex"] ?? "1";
            int index = 1;
            pageIndex.IsInt32(out index);
 
            PagingBar defaultBar = new PagingBar();
            defaultBar.LeftSize = 4;
            defaultBar.PageCount = 40;
            defaultBar.PageIndex = index;
            defaultBar.Url = "Default.aspx?pageIndex={0}";

　　　　 defaultBar.Target = "_black";
            Literal1.Text = defaultBar.BuildLinkHtml();
 
 
            PagingBar bar2 = new PagingBar("scott");
            bar2.LeftSize = 4;
            bar2.PageCount = 40;
            bar2.PageIndex = index;
            bar2.Url = "Default.aspx?pageIndex={0}";
            Literal2.Text = bar2.BuildLinkHtml();
 
            PagingBar bar3 = new PagingBar("green-black");
            bar3.LeftSize = 4;
            bar3.PageCount = 40;
            bar3.PageIndex = index;
            bar3.Url = "Default.aspx?pageIndex={0}";
            Literal3.Text = bar3.BuildLinkHtml();
 
            PagingBar bar4 = new PagingBar("quotes");
            bar4.LeftSize = 4;
            bar4.PageCount = 40;
            bar4.PageIndex = index;
            bar4.Url = "Default.aspx?pageIndex={0}";
            Literal4.Text = bar4.BuildLinkHtml();
             
        }
    }
}

　　　　PagingBar defaultBar = new PagingBar();
            defaultBar.LeftSize = 4;   //左边显示的链接数也就是说当这个参数为 4 时实际显示 9个链接总算显示的是奇数个链接
            defaultBar.PageCount = 40;     //总的页数
            defaultBar.PageIndex = index; //当前页
            defaultBar.Url = "Default.aspx?pageIndex={0}"; //链接的URL

　　　　 defaultBar.Target = "_black"; //页面在浏览器窗口中的打开方式可以为空
Literal1.Text = defaultBar.BuildLinkHtml(); //产生HTML 输出

这里是默认构造默认构造的话回去读取 web.config 需找配置的 CSS 样式名

需要在 appSettings 节点下添加配置

</appSettings>

不是默认构造的话可以使用一个带参构造

PagingBar bar4 = new PagingBar("quotes");

直接指定 css 名称
