Occurs when a key is pressed while focus is on this element.

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

public:
event KeyEventHandler^ KeyDown {
	virtual void add(KeyEventHandler^ value) sealed;
	virtual void remove(KeyEventHandler^ value) sealed;
}

Key handling interacts with other platform features such as commanding and text composition. The KeyDown event is a lower-level text input event that might not behave as expected on certain controls. This is because some controls have control compositing or class handling that provides a higher-level version of text input handling and related events.

This event creates an alias for the Keyboard::KeyDown attached event for this class so that KeyDown is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the KeyDown event are attached to the underlying Keyboard::KeyDown attached event and receive the same event data instance.
