How to: Animate a Boolean by Using Key Frames
This example shows how to animate the Boolean property value of a xref:System.Windows.Controls.Button control by using key frames.
Example
The following example uses the xref:System.Windows.Media.Animation.BooleanAnimationUsingKeyFrames class to animate the xref:System.Windows.UIElement.IsEnabled%2A property of a xref:System.Windows.Controls.Button control. All the key frames in this example use an instance of the xref:System.Windows.Media.Animation.DiscreteBooleanKeyFrame class. Discrete key frames like xref:System.Windows.Media.Animation.DiscreteBooleanKeyFrame create sudden jumps between values, that is, the movement of the animation is jerky.
