包含
TabControl
选项卡页，这些页由
TabPage
通过
TabPages
属性添加的对象表示。 此集合中选项卡页的顺序反映了选项卡显示在控件中的顺序。
用户可以通过单击控件中的选项卡之一来更改当前
TabPage
。 还可以使用以下属性之
TabControl
一以编程方式更改当前
TabPage
属性：
SelectedIndex
SelectedTab
在 .NET Framework 2.0 中，还可以使用以下方法之一：
SelectTab
DeselectTab
在 .NET Framework 2.0 中，可以通过处理下列事件之一来响应当前选项卡更改时：
Deselecting
Deselected
Selecting
Selected
中的
TabControl
选项卡属于各个控件的一部分
TabControl
，但不是各个
TabPage
控件的一部分。
TabPage
类的成员（如
ForeColor
属性）仅影响选项卡页的客户端矩形，但不影响选项卡。 此外，该方法
Hide
TabPage
不会隐藏选项卡。若要隐藏选项卡，必须从
TabControl.TabPages
集合中删除
TabPage
控件。
在 .NET Framework 2.0 中，选项卡被视为选项卡页的一部分，用于确定事件发生的时间
Enter
和
Leave
事件
TabPage
。 在早期版本的.NET Framework中，
Enter
焦点进入或离开选项卡时，不会发生焦点的和
Leave
事件
TabPage
，但仅当焦点进入或离开选项卡页的客户端矩形时才会发生。
除非集合中至少有一个
TabPage
：、、
Control.DoubleClick
、
Control.MouseDown
、
Control.MouseUp
Control.MouseHover
、、和
Control.MouseEnter
，
Control.MouseLeave
Control.MouseMove
否则不会为
TabControl
类引发以下事件。
TabControl.TabPages
Control.Click
如果集合中至少有一个
TabPage
，并且用户与选项卡控件的标头交互 (名称出现在) 的位置
TabPage
，则
TabControl
引发相应的事件。 但是，如果用户交互位于选项卡页内
ClientRectangle
，则会
TabPage
引发相应的事件。
在显示选项卡页之前，不会创建包含在其中的
TabPage
控件，并且这些控件中的任何数据绑定在显示选项卡页之前不会激活。
启用视觉样式并且属性
Alignment
设置为非
Top
值时，选项卡内容可能无法正确呈现。 若要解决此问题，可以使用所有者绘图自行绘制选项卡内容。 有关详细信息，请参阅
如何：使用 TabControl 显示Side-Aligned选项卡
。
当属性
Alignment
设置为非
Top
值且该
Appearance
属性设置为非
Normal
值时，选项卡页内容可能无法正确呈现。
