Controls animations with a timeline, and provides object and property targeting information for its child animations.
One or more of the following object elements that derive from Timeline: Storyboard, ColorAnimation, ColorAnimationUsingKeyFrames, DoubleAnimation, DoubleAnimationUsingKeyFrames, PointAnimation, or PointAnimationUsingKeyFrames. Object elements defined here become members of the Children collection when the Children property is accessed at run time.
You can use the interactive methods of the Storyboard object to start a storyboard automatically when an object loads or to start, pause, resume, and stop an animation.
A Storyboard is the only supported type of resource for the Resources property.
The following example shows how to use a Storyboard and an EventTrigger to create a rectangle that fades in and out of view after it is loaded.
