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.
