[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Defines a segment of time.

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

public abstract class Timeline : DependencyObject

The Timeline type exposes the following members.

Protected methodTimelineInitializes a new instance of the Timeline class.

Public propertyAutoReverseGets or sets a value that indicates whether the timeline plays in reverse after it completes a forward iteration.
Public propertyBeginTimeGets or sets the time at which this Timeline should begin.
Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyDurationGets or sets the length of time for which this timeline plays, not counting repetitions.
Public propertyFillBehaviorGets or sets a value that specifies how the animation behaves after it reaches the end of its active period.
Public propertyRepeatBehaviorGets or sets the repeating behavior of this timeline.
Public propertySpeedRatioGets or sets the rate, relative to its parent, at which time progresses for this Timeline.

Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public eventCompletedOccurs when the Storyboard object has completed playing.

Public fieldStatic memberAutoReversePropertyIdentifies the AutoReverse dependency property.
Public fieldStatic memberBeginTimePropertyIdentifies the BeginTime dependency property.
Public fieldStatic memberDurationPropertyIdentifies the Duration dependency property.
Public fieldStatic memberFillBehaviorPropertyIdentifies the FillBehavior dependency property.
Public fieldStatic memberRepeatBehaviorPropertyIdentifies the RepeatBehavior dependency property.
Public fieldStatic memberSpeedRatioPropertyIdentifies for the SpeedRatio dependency property.

A timeline represents a segment of time. It provides properties that enable you to specify the length of that segment, when it should start, how many times it will repeat, how fast time progresses in that segment, and more. Classes that derive from Timeline provide animation functionality (e.g. DoubleAnimation, ColorAnimation, etc.).
