Примеры

В следующем примере к прямоугольнику применяется ContentThemeAnimation.

<!-- 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; 
}
