This is most important class of the group timelines. It allows the execution of the timelines that contains, assigning the resulting values of each child to a different target if desired.

Also, a storyboard is mandatory to execute any animation from XAML. Even if it's a single animation, it must belong to a storyboard.

Members

  • TargetName (attached): if assigned to the storyboard, fixes the target object to apply the resulting animations of the children timelines, but every child can be assigned to it's own TargetName to animate a different object
  • Target (attached): similar to the above property, buy allows setting the target using a binding expression instead of by name
  • TargetProperty (attached): target property, that can also be specified at storyboard level, or at timeline child level.

Methods

  • Begin: Starts a storyboard animation by code. If the controllable parameter is set to null, the whole animation can be cancelled at any time using the Remove method
  • Remove: Stops the animation, removing from the targets the animated values set by the storyboard.
Ptr<DoubleAnimation> animation = NsCreateComponent<DoubleAnimation>();
animation->SetTo(40.0f);

Ptr<Storyboard> storyboard = NsCreateComponent<Storyboard>();
storyboard->GetChildren()->Add(animation);

storyboard->Begin(targetObject, true, HandoffBehavior_SnapshotAndReplace);
...
storyboard->Remove(targetObject);

Here is a complete XAML sample, starting an storyboard from a trigger event

<Button Content="Animate me!">
<Button.Triggers>
    <EventTrigger RoutedEvent="Button.Click">
    <EventTrigger.Actions>
        <BeginStoryboard>
            <Storyboard>
                <ThicknessAnimation Storyboard.TargetName="Border" Storyboard.TargetProperty="BorderThickness" To="20,20" AutoReverse="True"/>
                <ColorAnimation Storyboard.TargetName="Border" Storyboard.TargetProperty="Background.Color" From="Red" To="Green" AutoReverse="True" BeginTime="0:0:2"/>
                <PointAnimation Storyboard.TargetName="Rectangle" Storyboard.TargetProperty="Fill.Center" To="0.3,0.3" AutoReverse="True" BeginTime="0:0:4"/>
                <RectAnimation Storyboard.TargetName="Path" Storyboard.TargetProperty="Data.Rect" To="10,10,300,50" AutoReverse="True" BeginTime="0:0:6"/>
            </Storyboard>
        </BeginStoryboard>
    </EventTrigger.Actions>
    </EventTrigger>
</Button.Triggers>
</Button>
