Answer 1

Types of Animation (Storyboard) in Silverlight/WPF

1. DoubleAnimation: This will animate a Double Value from one value to another. So if you want to change the Width of a TextBox over time you need DoubleAnimation.

2. ColorAnimation: Same as the above if the type of Changing element is Color, you need ColorAnimation.

3. Transformation: This will animate the rendering of the shape (e.g Ractangle).
   There are a variety of transformations that can take place, such as stretching, skewing, rotating, etc.

4. SingleAnimation, RectAnimation, PointAnimation, Int32Animaition, ThicknessAnimation etc each of them bears the same meaning.

So basically the basis of Animation types is based on the type of the property for which you want your animation to work on.

Animation can also be categorized into two basic ways:

1. Animation Without KeyFrames: These are animation that only needs two values, From and To. It gives you a smooth animation based on the Timeline.DesiredFramerate property for the animation.

2. Animation With KeyFrames: Allows you to specify a KeyFrame collection which lets you define the KeyFrame value on a specified time. So that you can adjust your own animation based on specific time intervals.
