Occurs when this element gets text in a device-independent manner.
Assembly: PresentationCore (in PresentationCore.dll)
Theevent 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 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.
