SeekStoryboard Class

Definition

A trigger action that provides functionality for seeking (skipping) to a specified time within the active period of a Storyboard.

public ref class SeekStoryboard sealed : System::Windows::Media::Animation::ControllableStoryboardAction
public sealed class SeekStoryboard : System.Windows.Media.Animation.ControllableStoryboardAction
type SeekStoryboard = class
    inherit ControllableStoryboardAction
Public NotInheritable Class SeekStoryboard
Inherits ControllableStoryboardAction
Inheritance

Remarks

Use a SeekStoryboard action with an EventTrigger or a Trigger to seek a Storyboard.

Note that seek operations do not take the storyboard's SpeedRatio or SlipBehavior settings into account: the storyboard is treated as though it had a SpeedRatio of 1 and no SlipBehavior.

Seeking a Storyboard triggers its CurrentGlobalSpeedInvalidated and CurrentStateInvalidated events.

Pause, Resume, Stop, or Otherwise Control a Storyboard Interactively

To be able to pause, resume, or otherwise control a Storyboard interactively, set the Name property of its BeginStoryboard and use a ControllableStoryboardAction object (such as PauseStoryboard, ResumeStoryboard, or StopStoryboard) to control it by referencing its Name. If the Name of BeginStoryboard is unspecified, the Storyboard cannot be interactively controlled after it is begun. See How to: Use Event Triggers to Control a Storyboard After It Starts for more information.

Constructors

SeekStoryboard()

Initializes a new instance of the SeekStoryboard class.

Properties

BeginStoryboardName

Gets or sets the Name of the BeginStoryboard that began the Storyboard you want to interactively control.

(Inherited from ControllableStoryboardAction)
DependencyObjectType

Gets the DependencyObjectType that wraps the CLR type of this instance.

(Inherited from DependencyObject)
Dispatcher

Gets the Dispatcher this DispatcherObject is associated with.

(Inherited from DispatcherObject)
IsSealed

Gets a value that indicates whether this instance is currently sealed (read-only).

(Inherited from DependencyObject)
Offset

Gets or sets the amount by which the storyboard should move forward or backward from the seek origin Origin.

Origin

Gets or sets the position from which this seek operation's Offset is applied.

Methods

CheckAccess()

Determines whether the calling thread has access to this DispatcherObject.

(Inherited from DispatcherObject)
ClearValue(DependencyProperty)

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.

(Inherited from DependencyObject)
ClearValue(DependencyPropertyKey)

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey.

(Inherited from DependencyObject)
CoerceValue(DependencyProperty)

Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.

(Inherited from DependencyObject)
Equals(Object)

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.

(Inherited from DependencyObject)
GetHashCode()

Gets a hash code for this DependencyObject.

(Inherited from DependencyObject)
GetLocalValueEnumerator()

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject.

(Inherited from DependencyObject)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
GetValue(DependencyProperty)

Returns the current effective value of a dependency property on this instance of a DependencyObject.

(Inherited from DependencyObject)
InvalidateProperty(DependencyProperty)

Re-evaluates the effective value for the specified dependency property.

(Inherited from DependencyObject)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
OnPropertyChanged(DependencyPropertyChangedEventArgs)

Invoked whenever the effective value of any dependency property on this DependencyObject has been updated. The specific dependency property that changed is reported in the event data.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if it exists.

(Inherited from DependencyObject)
SetCurrentValue(DependencyProperty, Object)

Sets the value of a dependency property without changing its value source.

(Inherited from DependencyObject)
SetValue(DependencyProperty, Object)

Sets the local value of a dependency property, specified by its dependency property identifier.

(Inherited from DependencyObject)
SetValue(DependencyPropertyKey, Object)

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property.

(Inherited from DependencyObject)
ShouldSerializeOffset()

Returns a value that indicates whether the Offset property of this SeekStoryboard should be serialized.

ShouldSerializeProperty(DependencyProperty)

Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.

(Inherited from DependencyObject)
ToString()

Returns a string that represents the current object.

(Inherited from Object)
VerifyAccess()

Enforces that the calling thread has access to this DispatcherObject.

(Inherited from DispatcherObject)
