The following code example shows scenario 4 from the Input sample. This code shows some usage patterns for direct manipulation using the ManipulationStarting, ManipulationStarted, ManipulationDelta, ManipulationInertiaStarting, and ManipulationCompleted events.

private CompositeTransform _compositeTransform;

Constructors
ManipulationCompletedRoutedEventArgs() |
Initializes a new instance of the ManipulationCompletedRoutedEventArgs class. |
Properties
Container |
Gets the UIElement that is considered the container of the manipulation. |
Cumulative |
Gets the overall changes since the beginning of the manipulation. |
Handled |
Gets or sets a value that marks the routed event as handled. Setting to |
IsInertial |
Gets whether the ManipulationCompleted event occurs during inertia. |
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 |
Gets the PointerDeviceType for the pointer device involved in the manipulation. |
Position |
Gets the x- and y- screen coordinates of the touch input at completed position. |
Velocities |
Gets the velocities that are used for the manipulation. |
