설명

매개 변수는 desiredType 매개 변수를 변환해야 하는 value 형식을 나타내며 desiredType 셀의 FormattedValueType 속성이 할당됩니다. 예를 들어 셀이 그림 이름을 비트맵 value 으로 서식 지정하는 경우 는 String 그림 이름을 포함하는 이고 desiredType 는 형식을 Type 나타내는 Bitmap 입니다.

CellFormatting 이벤트 처리기가 속성을 셀에서 표시할 수 있는 형식으로 설정 Value 하지 않으면 , NullValue및 FormatProvider 속성을 사용하여 셀 내용의 서식이 Format지정됩니다.
