TabControl Styles and Templates

  • Artikel

This topic describes the styles and templates for the TabControl control. You can modify the default ControlTemplate to give the control a unique appearance. For more information, see Create a template for a control.

TabControl Parts

The following table lists the named parts for the TabControl control.

Part Type Description
PART_SelectedContentHost ContentPresenter The object that shows the content of the currently selected TabItem.

When you create a ControlTemplate for a TabControl, your template might contain an ItemsPresenter within a ScrollViewer. (The ItemsPresenter displays each item in the TabControl; the ScrollViewer enables scrolling within the control). If the ItemsPresenter is not the direct child of the ScrollViewer, you must give the ItemsPresenter the name, ItemsPresenter.

TabControl States

The following table lists the visual states for the TabControl control.

VisualState Name VisualStateGroup Name Description
Normal CommonStates The default state.
Disabled CommonStates The control is disabled.
Valid ValidationStates The control uses the Validation class and the Validation.HasError attached property is false.
InvalidFocused ValidationStates The Validation.HasError attached property is true has the control has focus.
InvalidUnfocused ValidationStates The Validation.HasError attached property is true has the control does not have focus.

TabItem Parts

The TabItem control does not have any named parts.

TabItem States

The following table lists the visual states for the TabItem control.

VisualState Name VisualStateGroup Name Description
Normal CommonStates The default state.
MouseOver CommonStates The mouse pointer is positioned over the control.
Disabled CommonStates The control is disabled.
Focused FocusStates The control has focus.
Unfocused FocusStates The control does not have focus.
Selected SelectionStates The control is selected.
Unselected SelectionStates The control is not selected.
Valid ValidationStates The control uses the Validation class and the Validation.HasError attached property is false.
InvalidFocused ValidationStates The Validation.HasError attached property is true has the control has focus.
InvalidUnfocused ValidationStates The Validation.HasError attached property is true has the control does not have focus.

TabControl ControlTemplate Example

The following example shows how to define a ControlTemplate for the TabControl and TabItem controls.
