Remarks
For event data, see TextCompositionStartedEventArgs.
This event occurs only when text is composed through an Input Method Editor (IME). Text composition events occur in the following order:
- TextCompositionStarted
- TextChanging
- TextChanged
- TextCompositionChanged
- TextCompositionEnded
After the TextCompositionStarted event, the TextChanging > TextChanged > TextCompositionChanged event cycle can occur multiple times before the TextCompositionEnded event occurs.
