Occurs when a key is pressed while focus is on this element.
Assembly: PresentationCore (in PresentationCore.dll)
Key handling interacts with other platform features such as commanding and text composition. Theevent 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 is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying Keyboard::KeyDown attached event and receive the same event data instance.
