Represents a visual behavior that occurs for predefined actions or state changes. Specific theme transitions (various Transition derived classes) can be applied to individual elements using the UIElement.Transitions property, or applied for scenario-specific theme transition properties such as ContentControl.ContentTransitions.

Remarks

Transition derived classes

Transition is the parent class for several immediately derived classes that define library theme transitions. Here are some of the notable derived classes:

For each of these classes, you typically define object elements. Most theme transitions don't have additional attributes, so you typically use a basic self-closing object element, for example <PopupThemeTransition />. These are used to populate a TransitionCollection property. Those properties include:

Not all transitions make sense for any given property. For example, PopupThemeTransition is really only useful for Popup.ChildTransitions. For more info on how to use the theme transitions, see Animations overview and topics linked from there, including the design guidelines topics.

Note

Prior to Windows 10, version 1809 (SDK 17763), the XAML syntax for properties that have a TransitionCollection value requires that you declare an explicit TransitionCollection object element as the value, and then provide object elements as child elements of TransitionCollection for each of the transition animations you want to use. In Windows 10, version 1809 (SDK 17763) or later, TransitionCollection supports the implicit collection usage, so you can omit the collection object element. For more info on implicit collections and XAML, see XAML syntax guide.

Properties

Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` represents a facility that can access the `DependencyObject` on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
