/** @event */ public void add_PreviewMouseDown (MouseButtonEventHandler value) /** @event */ public void remove_PreviewMouseDown (MouseButtonEventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
This event creates an alias for the Mouse.PreviewMouseDown attached event for this class, so that PreviewMouseDown is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the PreviewMouseDown event are attached to the underlying Mouse.PreviewMouseDown attached event and receive the same event data instance.
The PreviewMouseDown event is often raised together with either PreviewMouseLeftButtonDown or PreviewMouseRightButtonDown, which correspond to a press of one of the two standard mouse buttons. PreviewMouseLeftButtonDown or PreviewMouseRightButtonDown are also routed events, but they are direct routed events, and the appropriate button-specific event is raised when the Mouse.PreviewMouseDown event reaches this element along the event route. See Remarks for PreviewMouseLeftButtonDown or PreviewMouseRightButtonDown.
