Tip

For more info, design guidance, and code examples, see Connected animation.

If you have the WinUI 2 Gallery app installed, click here to open the app and see Connected Animation in action.

This example shows how to animate an image between two pages during a navigation.

SourcePage.xaml/SourcePage.xaml.cs

<Image x:Name="SourceImage"
       Width="200"
       Height="200"
       Stretch="Fill"
       Source="Assets/StoreLogo.png" />

private void NavigateToDestinationPage()
{
    ConnectedAnimationService.GetForCurrentView().PrepareToAnimate("image", SourceImage);
    Frame.Navigate(typeof(DestinationPage));
}

DestinationPage.xaml/DestinationPage.xaml.cs

<Image x:Name="DestinationImage"
       Width="400"
       Height="400"
       Stretch="Fill"
       Source="Assets/StoreLogo.png" />

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    base.OnNavigatedTo(e);

    ConnectedAnimation imageAnimation = 
        ConnectedAnimationService.GetForCurrentView().GetAnimation("image");
    if (imageAnimation != null)
    {
        imageAnimation.TryStart(DestinationImage);
    }
}

Remarks

To get an instance of ConnectedAnimationService, call the static GetForCurrentView method.

When you call PrepareToAnimate, you supply a key to associate with the newly created ConnectedAnimation returned by the method. You can later use this key to retrieve the same animation by calling GetAnimation. This lets you connect the animation between two different pages without having to manually pass the reference to the ConnectedAnimation object between pages.

See the Connected animation sample for a complete example of ConnectedAnimationService.

Properties
