Gets the collection of child Timeline objects.
The collection of child Timeline objects.
This property is read-only. You can use implicit collection syntax in XAML or methods of the TimelineCollection in script to add items or otherwise change the existing collection, but you cannot replace it with a different object. The default value is an empty collection.
The XAML syntax for Children is an example of an implicit collection syntax. In this case, because the property is read-only, neither the explicit property element tag <Storyboard.Children> nor the object element for the explicit collection <TimelineCollection> is permitted by the XAML parser. The implicit collection syntax of placing one or more child elements as direct child elements of a <Storyboard> object element is the only permitted XAML syntax. For more information about XAML implicit collection syntax, see XAML Syntax (Silverlight 1.0).
The Children property accepts one or more of any of the following: ColorAnimation, ColorAnimationUsingKeyFrames, DoubleAnimation, DoubleAnimationUsingKeyFrames, PointAnimation, PointAnimationUsingKeyFrames. It also accepts Storyboard. Nesting storyboards can be a useful technique for grouping or ungrouping animations that should sometimes play separately or sometimes together, or for applying properties such as RepeatBehavior (Timeline) to a group.
In scripting, you can get the value of Children and retain it for later operations against the collection, but you cannot set the Children property directly. Instead, you typically use CreateFromXaml to create a single node at a time, and then add that node to the TimelineCollection object by using the syntax object.Children.Add(xamlNode).
