Gets or sets a value that indicates whether the timeline plays in reverse after it completes a forward iteration. This is a dependency property.

Visual Basic (Declaration)
Public Property AutoReverse As Boolean
Dim instance As Timeline
Dim value As Boolean
value = instance.AutoReverse
instance.AutoReverse = value
public bool AutoReverse { get; set; }
public:
property bool AutoReverse {
bool get ();
void set (bool value);
}
public function get AutoReverse () : boolean
public function set AutoReverse (value : boolean)
<object AutoReverse="bool" .../>
Property Value
Type:
System..::.Boolean
true if the timeline plays in reverse at the end of each iteration; otherwise, false. The default value is false.
Dependency Property Information
If the AutoReverse property is set to true, the timeline plays for twice the length of time specified by its Duration property.
AutoReverse and Repetitions
When a timeline's AutoReverse property is set to true and its RepeatBehavior property causes it to repeat, each forward iteration is followed by a backward iteration. This makes one repetition. For example, a timeline with an AutoReverse value of true with an iteration Count of 2 would play forward once, then backwards, then forwards again, and then backwards again.
A timeline's AutoReverse property determines whether it plays in reverse after it completes a forward iteration. The following example shows several animations with identical duration and target values, but with different AutoReverse settings. To demonstrate how the AutoReverse property behaves with different RepeatBehavior settings, some animations are set to repeat. The last animation shows how the AutoReverse property works on nested timelines.
<!-- AutoReverseExample.xaml
This example shows how to use the AutoReverse property to make a timeline
play backwards at the end of each iteration.
Several rectangles are animated by DoubleAnimations with
identical durations and target values, but with different
AutoReverse and RepeatBehavior settings.-->
