Control authors use this attribute to specify the VisualState and VisualStateGroup objects that belong in their control's ControlTemplate. For example, suppose that you create a new control that has two visual states named Focused and Unfocused, both of which are in a VisualStateGroup named FocusStates. To specify to ControlTemplate authors that they can use those visual states, add two TemplateVisualStateAttribute attributes to the class signature of the control. Specify that the GroupName property is FocusStates and that the Name property is Focused for one and Unfocused for the other.

The following example shows the class signature for the NumericUpDown control. This example specifies that the NumericUpDown control uses four visual states. Two states, named Positive and Negative, are in the VisualStateGroup named ValueStates. The other two states, name Focused and Unfocused, are in the VisualStateGroup named FocusedStates. For the entire example, see Creating a Control That Has a Customizable Appearance.
