Discrete Keyframes

A discrete keyframe indicates that no interpolation should be done from the previous keyframe. Updating DoubleAnimationUsingKeyFrames from Listing 19.1 as follows produces the motion illustrated in Figure 19.11:

<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(Canvas.Top)"  Duration="0:0:3">  <Discrete DoubleKeyFrame Value="0" KeyTime="0:0:0"/>  <Discrete DoubleKeyFrame Value="200" KeyTime="0:0:1"/>  <Discrete DoubleKeyFrame Value="0" KeyTime="0:0:2"/>  <Discrete DoubleKeyFrame Value="200" KeyTime="0:0:3"/></DoubleAnimationUsingKeyFrames>
