The TabControl is useful for minimizing screen space usage while allowing an application to expose a large amount of data. A TabControl consists of multiple TabItem objects that share the same screen space. Only one TabItem in a TabControl is visible at a time. When a user selects the tab of a TabItem, the contents of that TabItem become visible and the contents of the other TabItem objects are hidden.
Content Model: TabControl is a ItemsControl. Its content properties are Items and ItemsSource. For more information on the content model for TabControl, see Controls Content Model Overview.
Dependency properties for this control might be set by the control’s default style. If a property is set by a default style, the property might change from its default value when the control appears in the application. The default style is determined by which desktop theme is used when the application is running. For more information, see Themes.
