Specifies that a control can be in a certain state and that a VisualState is expected in the control's ControlTemplate.

Examples
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.

Remarks
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.

Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
GetHashCode() |
Returns the hash code for this instance. (Inherited from Attribute) |
GetType() |
Gets the Type of the current instance. (Inherited from Object) |
IsDefaultAttribute() |
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
Match(Object) |
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute) |
