DataGridViewCellFormattingEventArgs.FormattingApplied 속성

  • 참조

정의

네임스페이스:
System.Windows.Forms
어셈블리:
System.Windows.Forms.dll

셀 값의 형식이 성공적으로 지정되었는지 여부를 나타내는 값을 가져오거나 설정합니다.

public:
 property bool FormattingApplied { bool get(); void set(bool value); };
public bool FormattingApplied { get; set; }
member this.FormattingApplied : bool with get, set
Public Property FormattingApplied As Boolean

속성 값

Boolean

셀 값의 형식이 처리되었으면 true이고, 그렇지 않으면 false입니다. 기본값은 false입니다.

설명

이벤트를 처리할 CellFormatting 때 추가 값 서식이 FormattingApplied 필요하지 않은 경우 속성을 true 설정한 Value 후 속성을 로 설정합니다. FormattingApplied 이벤트 처리기가 종료될 때 속성 값이 false 이면 속성에서 반환된 Format개체의 DataGridViewCellStyle , , FormatProviderNullValue및 DataSourceNullValue 속성에 표시된 대로 서식이 값에 CellStyle 적용됩니다.
