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">

                        <!—Reordering hint VisualStates of the ListViewItem control which use

Constructors

DragOverThemeAnimation()

Initializes a new instance of the DragOverThemeAnimation class.

Properties

AutoReverse	Gets or sets a value that indicates whether the timeline plays in reverse after it completes a forward iteration. (Inherited from Timeline)
BeginTime	Gets or sets the time at which this Timeline should begin. (Inherited from Timeline)
Direction	Gets or sets the direction that the target should translate, when the animation is active.
DirectionProperty	Identifies the Direction dependency property.
Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` represents a facility that can access the `DependencyObject` on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
Duration	Gets or sets the length of time for which this timeline plays, not counting repetitions. (Inherited from Timeline)
FillBehavior	Gets or sets a value that specifies how the animation behaves after it reaches the end of its active period. (Inherited from Timeline)
RepeatBehavior	Gets or sets the repeating behavior of this timeline. (Inherited from Timeline)
SpeedRatio	Gets or sets the rate, relative to its parent, at which time progresses for this Timeline. (Inherited from Timeline)
TargetName	Gets or sets the reference name of the control element being targeted.
TargetNameProperty	Identifies the TargetName dependency property.
ToOffset	Gets or sets the distance by which the target is translated when the animation is active.
ToOffsetProperty	Identifies the ToOffset dependency property.

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)

Events

Completed

Occurs when the Storyboard object has completed playing.
