Because of key combinations—either in default keyboards or through input method editors—multiple key events may raise just one text input event.
This event creates an alias for the TextCompositionManager.PreviewTextInput 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 TextCompositionManager.PreviewTextInput attached event and receive the same event data instance.
