ContentElement::KeyDown Event

Assembly: PresentationCore (in PresentationCore.dll)
public: event KeyEventHandler^ KeyDown { virtual void add(KeyEventHandler^ value) sealed; virtual void remove(KeyEventHandler^ value) sealed; }
Implements
IInputElement::KeyDownKey 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.
