Remarks

A key frame animation's target values are defined by its KeyFrames property, which contains a collection of ObjectKeyFrame objects. Each ObjectKeyFrame defines a segment of the animation with its own target Value and KeyTime. When the animation runs, it progresses from one key value to the next at the specified key times.

Animating the Key Frames of an ObjectAnimationUsingKeyFrames

You can't animate an object that is the output of another animation. For example, if you use an ObjectAnimationUsingKeyFrames to animate the Fill of a Rectangle from a RadialGradientBrush to a SolidColorBrush, you can't animate any properties of the RadialGradientBrush or SolidColorBrush.

Constructors

Initializes a new instance of the ObjectAnimationUsingKeyFrames class.
