库存预警：
通过某个属性值判断后，将某条数据的样式进行更改

属性扩展的方式，写一个返回string类型的属性，返回的是CSS样式表样式

 1  /// <summary>
 2     /// 性别
 3     /// </summary>
 4     public bool Sex
 5     {
 6         get { return _Sex; }
 7         set { _Sex = value; }
 8     }
 9 
10     public string SexStr
11     {
12         get { return _Sex ? "男" : "女"; }
13     }
14 
15 
16     private DateTime _Birthday;
17 
18     /// <summary>
19     /// 生日
20     /// </summary>
21     public DateTime Birthday
22     {
23         get { return _Birthday; }
24         set { _Birthday = value; }
25     }
26 
27     public string BirthdayStr
28     {
29         get { return _Birthday.ToString("yyyy年MM月dd日"); }
30     }
31 
32 
33     private string _Nation;
34 
35     /// <summary>
36     /// 民族
37     /// </summary>
38     public string Nation
39     {
40         get { return _Nation; }
41         set { _Nation = value; }
42     }
43 
44     public string NationName
45     {
46         get { return new NationData().Select(this._Nation).NationName; }
47 
48     }
49 
50     public string Age
51     {
52         get { return (DateTime.Now.Year - this._Birthday.Year).ToString(); }
53     }
54 
55     public string Red
56     {
57         get
58         {
59             string end = "";
60             if (Convert.ToInt32(Age) >= 16)
61             {
62                 end = "background-color:red;";
63             }
64             return end;
65         }
66     }

为了让大家知道，属性值不一定非得是展示用

光棒效果：

 1     <script type="text/javascript">
 2         window.onload = function () {
 3             var items = document.getElementsByClassName("tr_Item");
 4             var oldColor = "";
 5             for (var i = 0; i < items.length; i++) {
 6                 items[i].onmouseover = function () {
 7                     oldColor = this.style.backgroundColor;
 8                     this.style.backgroundColor = "yellow";
 9                 };
10                 items[i].onmouseout = function () {
11                     this.style.backgroundColor = oldColor;
12                 };
13             }
14         };
15     </script>
