Repeater：

HeaderTemplate - 在加载开始执行一遍

ItemTemplate - 有多少条数据，执行多少遍

FooterTemplate - 在加载最后执行一遍

AlternatingItemTemplate - 交替项模板

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

/// <summary>
    /// 性别
    /// </summary>
    public bool Sex
    {
        get { return _Sex; }
        set { _Sex = value; }
    }

    public string SexStr
    {
        get { return _Sex ? "男" : "女"; }
    }


    private DateTime _Birthday;

    /// <summary>
    /// 生日
    /// </summary>
    public DateTime Birthday
    {
        get { return _Birthday; }
        set { _Birthday = value; }
    }

    public string BirthdayStr
    {
        get { return _Birthday.ToString("yyyy年MM月dd日"); }
    }


    private string _Nation;

    /// <summary>
    /// 民族
    /// </summary>
    public string Nation
    {
        get { return _Nation; }
        set { _Nation = value; }
    }

    public string NationName
    {
        get { return new NationData().Select(this._Nation).NationName; }

    }

    public string Age
    {
        get { return (DateTime.Now.Year - this._Birthday.Year).ToString(); }
    }

    public string Red
    {
        get
        {
            string end = "";
            if (Convert.ToInt32(Age) >= 16)
            {
                end = "background-color:red;";
            }
            return end;
        }
    }
<ItemTemplate>
                <tr class="tr_Item" style="<%#Eval("Red")%>">
                    <td><%#Eval("UserName") %></td>
                    <td><%#Eval("PassWord") %></td>
                    <td><%#Eval("NickName") %></td>
                    <td><%#Eval("SexStr") %></td>
                    <td><%#Eval("BirthdayStr") %></td>
                    <td><%#Eval("Age") %></td>
                    <td><%#Eval("NationName") %></td>
                </tr>
            </ItemTemplate>

光棒效果

鼠标移入改变颜色

<style type="text/css">
        #tb1 {
            width: 100%;
            background-color: navy;

                items[i].onmouseover = function () {
                    oldColor = this.style.backgroundColor;
                    this.style.backgroundColor = "yellow";
                };
                items[i].onmouseout = function () {
