KeyEventHandler

  • The corresponding bubbling event is KeyUp.

  • Override OnPreviewKeyUp to implement class handling for this event in derived classes.

Remarks

Key handling interacts with other platform features such as commanding and text composition. The KeyUp 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. For details, check the documentation for individual controls.

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