AttachedCardShadow Class

Definition

Namespace:

Microsoft.Toolkit.Uwp.UI.Media

Assembly:

Microsoft.Toolkit.Uwp.UI.Media.dll

Package:

Microsoft.Toolkit.Uwp.UI.Media v7.1.2

A performant rectangular Windows.UI.Composition.DropShadow which can be attached to any Windows.UI.Xaml.FrameworkElement. It uses Win2D to create a clipped area of the outline of the element such that transparent elements don't see the shadow below them, and the shadow can be attached without having to project to another surface. It is animatable, can be shared via a resource, and used in a Windows.UI.Xaml.Style.

C#

public sealed class AttachedCardShadow : Microsoft.Toolkit.Uwp.UI.AttachedShadowBase

Inheritance

Windows.UI.Xaml.DependencyObject

AttachedShadowBase

AttachedCardShadow

Remarks

This shadow will not work on Windows.UI.Xaml.FrameworkElement which is directly clipping to its bounds (e.g. a Windows.UI.Xaml.Controls.Border using a Windows.UI.Xaml.Controls.Control.CornerRadius). An extra Windows.UI.Xaml.Controls.Border can instead be applied around the clipped border with the Shadow to create the desired effect. Most existing controls due to how they're templated will not encounter this behavior or require this workaround.
