tabs 控件

功能：
    将需要将页面中多个具备类似性质或功能的控件归纳为同一组的时候，可以使用"索引标签"来进行分类。这些分类的标签将被包含在同一个"索引标签容器"(TabContainer)中。

属性(TabContainer)：
    ActiveTabChanged :当我们单击索引标签时，并不会真正引发回送或回调动作，直到页面进行下一次的回送时，
          才会执行定义在这个事件处理函数内的程序代码。
          一般来说，我们会将这个事件设置为UpdatePane控件之AsyncPostBackTrigger类型触发器的控件事件。
    OnClientActiveTabChanged：当作用索引标签改变，并在客户端触发tabChanged事件时，所要执行的javascript程序代码。
    OnActiveTabChanged:指定当页面回送时，所要执行的服务器端函数。
    ActiveTabIndex:第一个要被显示的索引标签。
    CssClass:替每个索引标签指定一个自定义的CSS样式。
    Height:索引标签主体的高度（不将TabPanel的标题高度列入计算).
    Width:索引标签主体的宽度。
    ScrollBars: 在索引标签容器中，显示滚动条的方式，可以设置成下列几种：
     None:  不显示滚动条。
     Horizontal:只显示水平滚动条。
     Vertical: 只显示垂直滚动条。
     Both:同时显示水平和垂直滚动条。
     Auto:根据需要，自动显示最适当的滚动条。
