Como: Animate a Drop Shadow Visual Effect
O exemplo a seguir mostra como animar o ShadowDepth e Softness do DropShadowBitmapEffect para fazê-lo aparecer como o Button está levantando para fora da área da tela após ele ser clicado.
Exemplo
<Page xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml" >
<StackPanel>
<Button Margin="50" Width="200" Name="myButton">
Click Me to Animate Drop Shadow!
<Button.BitmapEffect>
<!-- This BitmapEffect is targeted by the animation. -->
<DropShadowBitmapEffect x:Name="myDropShadowBitmapEffect" Color="Black"
ShadowDepth="0" />
</Button.BitmapEffect>
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard>
<!-- Animate the movement of the button. -->
<ThicknessAnimation
Storyboard.TargetProperty="Margin" Duration="0:0:0.5"
From="50,50,50,50" To="0,0,50,50" AutoReverse="True" />
<!-- Animate shadow depth of the effect. -->
<DoubleAnimation
Storyboard.TargetName="myDropShadowBitmapEffect"
Storyboard.TargetProperty="ShadowDepth"
From="0" To="30" Duration="0:0:0.5"
AutoReverse="True" />
<!-- Animate shadow softness of the effect. As
the Button appears to get farther from the shadow,
the shadow gets softer. -->
<DoubleAnimation
Storyboard.TargetName="myDropShadowBitmapEffect"
Storyboard.TargetProperty="Softness"
From="0" To="1" Duration="0:0:0.5"
AutoReverse="True" />
</Storyboard>
