ContentElement::PreviewMouseDown Event

 

Occurs when any mouse button is pressed while the pointer is over this element.

Namespace:   System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

public:
event MouseButtonEventHandler^ PreviewMouseDown {
	void add(MouseButtonEventHandler^ value);
	void remove(MouseButtonEventHandler^ value);
}

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 and 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.
