Transition Transition Transition Class
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.

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.
The XAML syntax for all properties that use a TransitionCollection value is unusual in that you must 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. For most other XAML collection properties you could omit the collection object element because it can be implicit, but properties that use TransitionCollection don't support the implicit collection usage. For more info on implicit collections and XAML, see XAML syntax guide.
