Element. Key Down Event

public event System.Windows.Input.KeyEventHandler KeyDown;
member this.KeyDown : System.Windows.Input.KeyEventHandler
Public Custom Event KeyDown As KeyEventHandler
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.
