The corresponding bubbling event is TextInput.
Override OnPreviewTextInput to implement class handling for this event in derived classes.
The PreviewTextInput event allows a component or application to listen for text input in a device-independent manner. The keyboard is the primary means of PreviewTextInput; but speech, handwriting, and other input devices can also generate PreviewTextInput.
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 PreviewTextInput is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the PreviewTextInput event are attached to the underlying TextCompositionManager::PreviewTextInput attached event and receive the same event data instance.
