The event occurs on an element that has the IsManipulationEnabled property set to true when the user puts a finger on it. By default, subsequent manipulation events report the position of the manipulation relative to the element that has IsManipulationEnabled set to true. You can specify that the position should be relative to another element by setting the ManipulationContainer property. For example, you can make the manipulation relative to the parent of the element.
You can also do the following in an event handler for :
Specify whether the user needs more than one finger to perform the manipulations by setting the ManipulationStartingEventArgs.IsSingleTouchEnabled property.
Specify the center of a single-finger rotation by setting the ManipulationStartingEventArgs.Pivot property.
Cancel the manipulation by calling the ManipulationStartingEventArgs.Cancel method.
For more information about manipulations, see the Input Overview. For an example of an application that responds to manipulations, see Walkthrough: Creating Your First Touch Application.
The following example shows the event handler for the event and sets the ManipulationContainer to the parent element that receives the manipulation events so that the coordinates of the manipulation are relative to the parent element. This example is part of a larger example in Walkthrough: Creating Your First Touch Application.
