ElasticEase.Springiness Property

Gets or sets the stiffness of the spring. The smaller the Springiness value is, the stiffer the spring and the faster the elasticity decreases in intensity over each oscillation.

Namespace:  System.Windows.Media.Animation
Assembly:  PresentationCore (in PresentationCore.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
public double Springiness { get; set; }
<ElasticEase Springiness="double"/>

Property Value

Type: System.Double
A positive number that specifies the stiffness of the spring. The default value is 3.

The smaller the Springiness value is, the stiffer the spring and the faster the elasticity decreases in intensity over each oscillation.

Dependency property identifier field: SpringinessProperty

The following diagram illustrates the effect of different values of Springiness.

Demonstrates different Springiness values.

The following example applies an ElasticEase easing function to a DoubleAnimation to create an animation that resembles a spring oscillating back and forth until it comes to rest.

<Rectangle Name="myRectangle" Width="200" Height="30" Fill="Blue">
    <Rectangle.Triggers>
        <EventTrigger RoutedEvent="Rectangle.MouseDown">
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation From="30" To="200" Duration="00:00:4" 
                     Storyboard.TargetName="myRectangle" 
                     Storyboard.TargetProperty="Height">
                        <DoubleAnimation.EasingFunction>

                            <!-- Elastic easing function assigned to From/To animation -->
                            <ElasticEase x:Name="myElasticEase" Oscillations="3" 
                             Springiness="1" EasingMode="EaseOut"/>
                        </DoubleAnimation.EasingFunction>
                    </DoubleAnimation>

                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Rectangle.Triggers>

</Rectangle>
