Controls animations with a timeline, and provides object and property targeting information for its child animations.
To create an object using scripting, see CreateFromXAML.
|oneOrMoreChildTimelines||One or more object elements that derive from Timeline. These can be one or more of the following: Storyboard, ColorAnimation, ColorAnimationUsingKeyFrames, DoubleAnimation, DoubleAnimationUsingKeyFrames, PointAnimation, PointAnimationUsingKeyFrames. Object elements defined here become members of the collection held by the Children property, when accessed by scripting at runtime.|
In addition to starting a storyboard automatically when an object loads, you can use the interactive methods of the Storyboard object to start, pause, resume, and stop an animation. For more information, see Interactive Animations Overview.
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 make a rectangle that fades in and out of view after it is loaded.
