ContentTransitions property

ContentControl.ContentTransitions property

Gets or sets the collection of Transition style elements that apply to the content of a ContentControl.


Public Property ContentTransitions As TransitionCollection


XAML Values


One or more object elements instantiating types that are derived from the Transition base type. Typically there is only one of each type of transition included in the collection.

Property value

Type: TransitionCollection

The strongly typed collection of Transition style elements.


Important  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.

Transition animations play a particular role in UI design of your app. The basic idea is that when there is a change or transition, the animation draws the attention of the user to the change.It's not common to set the value of the ContentTransitions property directly on a ContentControl type that is a direct element of app UI. It's more common to have a transitions collection be a part of a visual state, template or style. In this case you use mechanisms such as Setter of a Style to specify the ContentTransitions property. Styles are typically stored as a XAML resource.
