PropertyAccess typeDescription

AutoReverse

BeginTime

Read/writeGets or sets the time at which this Timeline should begin. (Inherited from Timeline)

Direction

Read/writeGets or sets the direction that the target should translate, when the animation is active.

DirectionProperty

Read-onlyIdentifies the Direction dependency property.

Dispatcher

Read-onlyGets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)

Duration

Read/writeGets or sets the length of time for which this timeline plays, not counting repetitions. (Inherited from Timeline)

FillBehavior

Read/writeGets or sets a value that specifies how the animation behaves after it reaches the end of its active period. (Inherited from Timeline)

Examples

The following is an example of a template for a custom control that animates as another element is being dragged over it.


<Style x:Key="ListViewItemStyle1" TargetType="ListViewItem">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ListViewItem">
                <Border x:Name="OuterContainer">
                    <VisualStateManager.VisualStateGroups>                        
                        <!—Reordering hint VisualStates of the ListViewItem control which use 
                             DragOverThemeAnimation. -->
