C#에 DataGrid를 다루다 보면 cell BeginEdit(셀 에디트를 위해)를 호출 하게 되는데 , 이때 영어 같은 경우는 합성 문자가 아니기 때문에 상관이 없지만, 한글 같은 경우는 합성 문자이기때문에 첫번째 타이핑을 할때 IME_Composition 인 상태의 커서를 만들어야 한글 입력이 제대로 된다.
하지만 DataGrid(WPF)의 경우에는 딱히 지원이 없어 보인다. 또 나같은 경우는 한글키 입력 일경우에는 KEY_DOWN 메세지 자체를 프로그램에서 캐치 하지 못했다. 해서 전역 후킹을 통해서 이문제를 해결했다.

SetHook() 을 호출하면 키보드 후킹이 시작되고, UnHook()를 호출하면 후킹이 종료 된다.
C#프로그램을 하다가 막히면 결국 WinApi를 사용해서 해결해야 하니, 아무래도 윈도우 Application 개발자는 C++(WinApi)을 기본적으로 알면 많은 도움이 될것 같다.
