Remarks
Obtain instances of this object through the AnimationDescription.animations property.
When a property animation is playing, that animation can be replaced by a different animation before the first animation is finished. The second animation can start from the same point at which the first animation leaves off. There is a slight delay between the time that the second animation is instructed to begin and when it does. In Windows 8, this can lead to a visible jump in the animation because the first animation has progressed slightly further during that delay. Starting in Windows 8.1, the starting point of the second animation is recalculated at the time it begins so no jump is seen.
The timing controls Control1 and Control2 specify the location of the first and second control points of a cubic Bézier curve. These two points have the same meaning as they do in the CSS transition-timing-function property. Control point zero is always (0,0) and control point three is always (1,1). The coordinates of Control1 and Control2 are always in the range 0 to 1, inclusive.
On the resulting Bézier curve, the x-coordinate represents time and the y-coordinate represents progress. The raw curve from (0,0) to (1,1) is scaled to match the actual duration and range of the animated transition, such that x=0 is the starting time of the transform, x=1 is the ending time, y=0 is the initial value of the animated property, and y=1 is the final value. Values of x and y between 0 and 1 represent corresponding intermediate values of time and the animation.
Properties
Control1 Control1 Control1 Control1
Gets the location of the first control point for the cubic Bézier curve that describes how this property of this object should animate over time.
public : Point Control1 { get; }public Point Control1 { get; }Public ReadOnly Property Control1 As Point// You can use this property in JavaScript.

Control2 Control2 Control2 Control2
Gets the location of the second control point for the cubic Bézier curve that describes how this property of this object should animate over time.
public : Point Control2 { get; }public Point Control2 { get; }Public ReadOnly Property Control2 As Point// You can use this property in JavaScript.
- See Also
Delay Delay Delay Delay
Gets the amount of time between when the animation is instructed to begin and when that animation actually begins to draw.
public : TimeSpan Delay { get; }public TimeSpan Delay { get; }Public ReadOnly Property Delay As TimeSpan// You can use this property in JavaScript.
- Value
- TimeSpan TimeSpan TimeSpan TimeSpan
The amount of time to delay before starting an animation.
Remarks
This delay is in addition to any StaggerDelay applied to the parent AnimationDescription. For instance, if a transition is scheduled through the application of StaggerDelay and StaggerDelayFactor to begin at time t=200 ms and this delay is set to 250 ms, then the transition will actually begin to animate at 450 ms.
- See Also
Duration Duration Duration Duration
Gets the amount of time over which the animation should be performed. This does not include the delay.
public : TimeSpan Duration { get; }public TimeSpan Duration { get; }Public ReadOnly Property Duration As TimeSpan// You can use this property in JavaScript.
- Value
- TimeSpan TimeSpan TimeSpan TimeSpan
The duration of the animation.
Remarks
The duration can be 0, in which case all animated properties are instantly set to their final values and no animation is shown.

Type Type Type Type
Gets the type of animation represented by this object.
public : PropertyAnimationType Type { get; }public PropertyAnimationType Type { get; }Public ReadOnly Property Type As PropertyAnimationType// You can use this property in JavaScript.
One of the animation type values.
Remarks
The PropertyAnimation object can be cast to the derived object described by its type. See PropertyAnimationType for a list of types and their corresponding objects.
