Gets or sets an object that describes the pivot for a single-point manipulation.
Assembly: PresentationCore (in PresentationCore.dll)
When you set the property, the manipulation will contain rotation data when the user uses one finger during a manipulation. This is to simulate real-world situations where you can use one finger to rotate an object, such as a piece of paper on a table. If the is a null reference (Nothing in Visual Basic), the user must use two fingers to cause rotation.
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 an event handler for the ManipulationStarting event and sets the property. To test this example, follow the steps in Walkthrough: Creating Your First Touch Application and replace the code in step 4 with this code.
