Examples

This example shows the XAML syntax for setting a TransitionCollection object element as part of setting the UIElement.Transitions property inline.

<Button Content="EntranceThemeTransition Button">
    <Button.Transitions>
        <TransitionCollection>
            
            <!-- This transition just uses the default behavior which is to
                 have the button animate into view from the right. You can
                 make it start from anywhere on the right by using the
                 FromHorizontalOffset property. If you'd rather see a vertical
                 animation, use the FromVerticalOffset property. -->
            <EntranceThemeTransition />
        </TransitionCollection>
    </Button.Transitions>
</Button>

<Grid Background="{StaticResource ApplicationPageBackgroundBrush}">
    <Grid.Resources>
        <Style x:Key="DefaultButtonStyle" TargetType="Button">
            <Setter Property="Transitions">
                <Setter.Value>
                    <TransitionCollection>
                        <EntranceThemeTransition/>
                    </TransitionCollection>
                </Setter.Value>
            </Setter>
        </Style>
    </Grid.Resources>

    <Button Style="{StaticResource DefaultButtonStyle}" 
            Content="EntranceThemeTransition style applied" />

</Grid>

Remarks

TransitionCollection is used as the value type for these properties:

• Border.ChildTransitions
• ContentControl.ContentTransitions (on content controls such as Button or AppBar)
• ContentPresenter.ContentTransitions
• ItemsControl.ItemContainerTransitions (on items controls such as GridView, ListBox, ListView and Selector)
• ItemsPresenter.FooterTransitions
• ItemsPresenter.HeaderTransitions
• ListViewBase.FooterTransitions
• ListViewBase.HeaderTransitions
• Panel.ChildrenTransitions (on Grid, StackPanel and other panels)
• Popup.ChildTransitions
• SettingsFlyoutTemplateSettings.ContentTransitions
• UIElement.Transitions (on hundreds of classes)

Transition animations are preconfigured animations from the Windows Runtime animation library. Transition animations run automatically upon the conditions that the transition animation is associated with, using the property owner where the TransitionCollection is set as the target. The properties being animated vary depending on which transition you use.

VisualStateGroup.Transitions does not use the TransitionCollection type. VisualStateGroup.Transitions uses a built-in collection(list or vector) of VisualTransition objects.

Enumerating the collection in C# or Microsoft Visual Basic

A TransitionCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<Transition> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with a Transition constraint.
