Occurs when a Button is tapped.
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
Instead of using MouseLeftButtonDown or MouseLeftButtonUp, you should use the event to detect a button tap by the user. Because of the way that the ButtonBase class handles user tap events, MouseLeftButtonDown and MouseLeftButtonUp events do not occur when the click mode is a value other than Hover.
