예제

다음 코드 예제에서는 PerformLayout 메서드를 사용하는 방법을 보여 줍니다. 또한 이벤트가 발생하는 Layout 방법을 보여 줍니다. 이 예제 Click 에서 에 대한 Button1 이벤트 처리기는 를 명시적으로 호출합니다 PerformLayout. Click 의 Button2 이벤트 처리기는 를 암시적으로 호출합니다PerformLayout. PerformLayout 은 양식이 로드될 때 호출됩니다. Button3 는 컨트롤을 로드할 때의 상태로 반환합니다. 각 경우에 Layout 이벤트가 발생합니다.

설명

메서드를 SuspendLayout 호출하기 전에 메서드 Layout 를 PerformLayout 호출한 경우 이벤트가 표시되지 않습니다.

및 affectedProperty 매개 변수는 affectedControl 모두 로 null설정할 수 있습니다. 이렇게 하면 만든 의 AffectedControl 및 AffectedProperty 속성이 LayoutEventArgs 로 설정 null됩니다.

설명

메서드를 SuspendLayout 호출하기 전에 메서드 Layout 를 PerformLayout 호출한 경우 이벤트가 표시되지 않습니다.

AffectedControl 메서드를 호출할 null 때 값이 LayoutEventArgs 제공되지 않은 경우 만든 의 및 AffectedProperty 속성이 로 PerformLayout 설정됩니다.
