Remarks

The IXRStoryboard class uses IXRTimelineCollection to store objects derived from IXRTimeline. IXRStoryboard uses this collection to store the animations that belong to a storyboard.

To obtain a pointer to this collection, call IXRStoryboard::GetChildren. Then, use the methods of this class to add, remove, or retrieve items. To clear the complete collection, call the IXRTimelineCollection::Clear method.

When you create a class instance, use an IXRTimelineCollectionPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

You can define a timeline collection in Microsoft Silverlight 3 XAML.
