Remarks

Key handling interacts with other platform features such as commanding and text composition. This event creates an alias for the Keyboard.PreviewKeyDown attached event for this class, so that PreviewKeyDown is part of the class members list when UIElement3D is inherited as a base element. Event handlers that are attached to the PreviewKeyDown event are attached to the underlying Keyboard.PreviewKeyDown attached event and receive the same event data instance.

PreviewKeyDown is introduced in the .NET Framework version 3.5. For more information, see Versions and Dependencies.
