![]() SolidColorBrush mySolidColorBrush = new SolidColorBrush(Colors.Blue) ![]() This.RegisterName(myRectangle.Name, myRectangle) NameScope.SetNameScope(this, new NameScope()) StackPanel myStackPanel = new StackPanel() This.WindowTitle = "Storyboards Example" The following example uses a Storyboard to animate the Width of a Rectangle element and the Color of a SolidColorBrush used to paint that Rectangle. How to: Trigger an Animation When Data Changes Trigger an Animation When a Property Value ChangesīeginStoryboard and a property MultiTrigger "Per-Instance" refers to the technique of applying an animation or storyboard directly to instances of an object, rather than in a style, control template, or data template. The following table shows the different places where each Storyboard begin technique is supported: per-instance, style, control template, and data template. In code, you can also use the Begin method. In XAML, you use a BeginStoryboard object with an EventTrigger, Trigger, or DataTrigger. To apply animations to their targets, you begin the Storyboard using a trigger action or a method. You set these properties on an animation to specify its target object and property. The Storyboard class provides the Storyboard.TargetName and Storyboard.TargetProperty attached properties. To use a Storyboard to organize and apply animations, you add the animations as child timelines of the Storyboard. How to Apply Animations with a Storyboard However, you could not use a Storyboard to animate a SolidColorBrush that did not register its name with a FrameworkElement or FrameworkContentElement, or was not used to set a property of a FrameworkElement or FrameworkContentElement. In code, animate a SolidColorBrush declared by a class that also contains a FrameworkElement, if the SolidColorBrush registered its name with that FrameworkElement. However, because storyboarding is a framework-level feature, the object must belong to the NameScope of a FrameworkElement or a FrameworkContentElement.įor example, you could use a Storyboard to do the following:Īnimate a SolidColorBrush (Non-framework element) that paints the Background of a Button (a type of FrameworkElement),Īnimate a SolidColorBrush (Non-framework element) that paints the fill of a GeometryDrawing (Non-framework element) displayed using an Image ( FrameworkElement). Storyboard objects enable you to organize animations and apply them in groups to one or more objects.Ī Storyboard can be used to animate dependency properties of animatable classes (for more information about what makes a class animatable, see the Animation Overview). In this case, you have multiple sets of animations that apply to the same object, and you want to play at different times, dependent on the state of the button. Shrink and fade to 50 percent opacity when it becomes disabled. Shrink away and then grow back to its original size when clicked. ![]() Grow and change color when the user selects the button. For example, suppose you want a button that does these three things. Storyboard objects enable you to combine timelines that affect a variety of objects and properties into a single timeline tree, making it easy to organize and control complex timing behaviors. ![]() A Storyboard can contain any type of Timeline, including other container timelines and animations. Container timelines derive from the TimelineGroup class, and include ParallelTimeline and Storyboard.Ī Storyboard is a type of container timeline that provides targeting information for the timelines it contains. Other timeline classes are provided to help you organize sets of timelines, and to apply timelines to properties. For more information about attached properties, see the Attached Properties Overview.Īnimations are not the only useful type of timeline. You should also know how to use attached properties. For an introduction to animation, see the Animation Overview. To understand this topic, you should be familiar with the different animation types and their basic features. It describes how to interactively manipulate Storyboard objects and describes indirect property targeting syntax. This topic shows how to use Storyboard objects to organize and apply animations.
