Repeater控件第前10笔记录高亮显示

很久以前，Insus.NET有写类似的，只不过是在GridView控件实现。
但有网友做着做，把控件改为Repeater控件实现不了。

现Insus.NET再实现它一次，算是练习了。先准备好数据，写一个类别：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

/// <summary>
/// Summary description for Article
/// </summary>
namespace Insus.NET
{
    public class Article
    {
        private int _Article_nbr;
        private string _Title;
        private string _Author;
        private DateTime _PostDate;

        public int Article_nbr
        {
            get { return _Article_nbr; }
            set { _Article_nbr = value; }
        }
        public string Title
        {
            get { return _Title; }
            set { _Title = value; }
        }
        public string Author
        {
            get { return _Author; }
            set { _Author = value; }
        }
        public DateTime PostDate
        {
            get { return _PostDate; }
            set { _PostDate = value; }
        }
        
        public Article()
        {
            //
            // TODO: Add constructor logic here
            //
        }
    }
}
