Method	Description
ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)

Properties

The DragOverThemeAnimation class has these properties.

Property	Access type	Description
AutoReverse	Read/write	Gets or sets a value that indicates whether the timeline plays in reverse after it completes a forward iteration. (Inherited from Timeline)
BeginTime	Read/write	Gets or sets the time at which this Timeline should begin. (Inherited from Timeline)
Direction	Read/write	Gets or sets the direction that the target should translate, when the animation is active.
DirectionProperty	Read-only	Identifies the Direction dependency property.
Dispatcher	Read-only	Gets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)
Duration	Read/write	Gets or sets the length of time for which this timeline plays, not counting repetitions. (Inherited from Timeline)
FillBehavior	Read/write	Gets or sets a value that specifies how the animation behaves after it reaches the end of its active period. (Inherited from Timeline)
RepeatBehavior	Read/write	Gets or sets the repeating behavior of this timeline. (Inherited from Timeline)
SpeedRatio	Read/write	Gets or sets the rate, relative to its parent, at which time progresses for this Timeline. (Inherited from Timeline)
TargetName	Read/write	Gets or sets the reference name of the control element being targeted.
TargetNameProperty	Read-only	Identifies the TargetName dependency property.
ToOffset	Read/write	Gets or sets the distance by which the target is translated when the animation is active.
ToOffsetProperty	Read-only	Identifies the ToOffset dependency property.

Remarks

Note that setting the Duration property has no effect on this object since the duration is preconfigured.

Examples

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

XAML

    <Setter Property="Template">
