What should I do to achive that ?

UIElement has the ManipulationStarted event. The ManipulationStartedEventArgs has a property named Manipulators (IEnumerable). The count of Manipulators is the number of contacts being used (e.g. 2 elements would mean 2 fingers).

Also available is the ManipulationDelta event. The args there also has a Manipulators property.
