Examples

The following example applies a ContentThemeAnimation to a rectangle.

<!-- The ContentThemeTransition will execute when the ContentControl’s content changes. -->        
<ContentControl x:Name="ContentHost" PointerPressed="ContentHost_PointerPressed">
    <ContentControl.ContentTransitions>
        <TransitionCollection>
            <ContentThemeTransition/>
        </TransitionCollection>
    </ContentControl.ContentTransitions>
    <Rectangle Height="200" Width="200" Fill="Orange"/>
</ContentControl>

private void ContentHost_PointerPressed(object sender, PointerRoutedEventArgs e)
{
    // Replace the ContentControl's content with a new Rectangle of a random color.
    Rectangle newItem = new Rectangle();
    Random rand = new Random();

    newItem.Height = 200;
    newItem.Width = 200;
    newItem.Fill = new SolidColorBrush(Color.FromArgb(255, 
         (byte)rand.Next(0, 255), (byte)rand.Next(0,255), (byte)rand.Next(0, 255)));

    ContentHost.Content = newItem; 
}

void ContentHost_PointerPressed(Windows::Foundation::IInspectable const& /* sender */,
    Windows::UI::Xaml::Input::PointerRoutedEventArgs const& /* e */)
{
    // Replace the ContentControl's content with a new Rectangle of a random color.
    Windows::UI::Xaml::Shapes::Rectangle newItem;

    newItem.Height(200);
    newItem.Width(200);

    Windows::UI::Color color;
    color.R = std::rand() % 256;
    color.G = std::rand() % 256;
    color.B = std::rand() % 256;

    newItem.Fill(Windows::UI::Xaml::Media::SolidColorBrush{ color });

    ContentHost().Content(newItem);
}

void MyPage::ContentHost_PointerPressed(Object^ sender, PointerRoutedEventArgs^ e)
{
    // Replace the ContentControl's content with a new Rectangle of a random color.
    Rectangle^ newItem = ref new Rectangle();

    newItem->Height = 200;
    newItem->Width = 200;

    Color color;
    color.R = rand() % 256;
    color.G = rand() % 256;
    color.B = rand() % 256;

    newItem->Fill = ref new SolidColorBrush(color);

    ContentHost->Content = newItem; 
}

Remarks

Note that setting the Duration property has no effect on this object since the duration is preconfigured.

Constructors

ContentThemeTransition()

Initializes a new instance of the ContentThemeTransition class.

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)
HorizontalOffset	Gets or sets the distance by which the target is translated in the horizontal direction when the transition is active.
HorizontalOffsetProperty	Identifies the HorizontalOffset dependency property.
VerticalOffset	Gets or sets the distance by which the target is translated in the vertical direction when the transition is active.
VerticalOffsetProperty	Identifies the VerticalOffset dependency property.

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)
