The event allows a component or application to listen for text input in a device-independent manner. The keyboard is the primary means of ; but speech, handwriting, and other input devices can also generate .
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 ContentElement 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.
