ManipulationCompletedRoutedEventArgs() ManipulationCompletedRoutedEventArgs() ManipulationCompletedRoutedEventArgs()

Initializes a new instance of the ManipulationCompletedRoutedEventArgs class.

public : ManipulationCompletedRoutedEventArgs()
public ManipulationCompletedRoutedEventArgs()
Public Sub New()


Container Container Container

Gets the UIElement that is considered the container of the manipulation.

public : UIElement Container { get; }
public UIElement Container { get; }
Public ReadOnly Property Container As UIElement
UIElement UIElement UIElement

The UIElement that is considered the container of the manipulation.

Cumulative Cumulative Cumulative

Gets the overall changes since the beginning of the manipulation.

public : ManipulationDelta Cumulative { get; }
public ManipulationDelta Cumulative { get; }
Public ReadOnly Property Cumulative As ManipulationDelta
ManipulationDelta ManipulationDelta ManipulationDelta

The overall changes since the beginning of the manipulation.

Handled Handled Handled

Gets or sets a value that marks the routed event as handled. Setting to true prevents most handlers along the event route from handling the same event again.

public : Platform::Boolean Handled { get; set; }
public bool Handled { get; set; }
Public ReadWrite Property Handled As bool
Platform::Boolean bool bool

true to mark the routed event handled; false to leave the routed event unhandled, which permits the event to potentially route further. The default is false.

IsInertial IsInertial IsInertial

Gets whether the ManipulationCompleted event occurs during inertia.

public : Platform::Boolean IsInertial { get; }
public bool IsInertial { get; }
Public ReadOnly Property IsInertial As bool
Platform::Boolean bool bool

true if the ManipulationCompleted event occurs during inertia; false if the event occurs while the user's input device has contact with the element.

OriginalSource OriginalSource OriginalSource

Gets a reference to the object that raised the event. This is often a template part of a control rather than an element that was declared in your app UI.

(Inherited from RoutedEventArgs)

PointerDeviceType PointerDeviceType PointerDeviceType

Gets the PointerDeviceType for the pointer device involved in the manipulation.

public : PointerDeviceType PointerDeviceType { get; }
public PointerDeviceType PointerDeviceType { get; }
Public ReadOnly Property PointerDeviceType As PointerDeviceType
PointerDeviceType PointerDeviceType PointerDeviceType

A value of the enumeration.

Position Position Position

Gets the x- and y- screen coordinates of the touch input at completed position.

public : Point Position { get; }
public Point Position { get; }
Public ReadOnly Property Position As Point
Point Point Point

The x- and y- screen coordinates of the touch input at completed position.

Velocities Velocities Velocities

Gets the velocities that are used for the manipulation.

public : ManipulationVelocities Velocities { get; }
public ManipulationVelocities Velocities { get; }
Public ReadOnly Property Velocities As ManipulationVelocities
ManipulationVelocities ManipulationVelocities ManipulationVelocities

The velocities that are used for the manipulation.
