Occurs when text continues to be composed via an input method editor (IME).
Assembly: System.Windows (in System.Windows.dll)
Use a handler based on TextCompositionEventHandler to handle this event.
The scenario for handling this event from a focused UI element as opposed to handling TextInput is exclusively for processing IME input. Generally, IME is only enabled for text input controls (TextBox specifically, and derived classes).
This event is a bubbling event. This means that if multiple handlers are registered for a sequence of objects connected by parent-child relationships in the object tree, the event is received by each object in that relationship, with the route going in the parent direction. The sender available to the event handler identifies the object where the event is handled, not necessarily the object that actually received the input condition that initiated the event. To get the object that initiated the event, use the OriginalSource value of the event's RoutedEventArgs event data. For more information on routed event concepts, see Events Overview for Silverlight.
