Timeline.AutoReverse Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

Namespace:  System.Windows.Media.Animation
Assembly:  System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Property AutoReverse As Boolean
public bool AutoReverse { get; set; }
<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.

Remarks

Dependency property identifier field: AutoReverseProperty

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.
