Remarks

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 the user selects a TabItem, the content of that TabItem become visible and the content of other TabItem objects are hidden. You can specify which tab item displays with the SelectedIndex or the SelectedItem property.

NoteNote:

The TabControl control is available as part of the libraries in the Silverlight Software Development Kit (SDK). For more information, see the Silverlight Tools.

Customizing the TabControl Control

To apply the same property settings to multiple TabControl controls, use the Style property. To change the visual structure and visual behavior of a TabControl, copy and modify its default style and template. For more information, see Control Customization.

Dependency properties for this control might be set by the default style of the control. If a dependency property for a TabControl is set by its default style, the property might change from its default value when the TabControl appears in the application. For more information, see Dependency Property Value Precedence. You can get the default style and template for ScrollViewer from TabControl Styles and Templates.

NoteNote:

Setting a visual property will only have an effect if that property is both present in TabControl control's default template and is set by using a TemplateBinding. You can find a list of visual properties in the "Changing the Visual Structure of a Control" section of Customizing the Appearance of an Existing Control by Using a ControlTemplate.

Examples

The following XAML and code creates two TabControl objects, populates them with information, and handles the SelectionChanged event.
