설명

클래스는 DataGridViewBand DataGridViewCell 그룹으로 조작할 수 있는 밴드에서 함께 조인된 요소를 나타냅니다. 각 요소는 일반적으로 파생 클래스 중 DataGridViewCell 하나 또는 의 instance. DataGridViewHeaderCell 은 각 밴드와 연결되어 있지만 헤더 셀은 대역의 요소로 간주되지 않습니다.

DataGridViewBand는 및 DataGridViewColumn 클래스의 DataGridViewRow 기본 클래스입니다. 형식에 대한 DataGridViewBand 공용 생성자가 없으므로 밴드에 액세스하는 유일한 방법은 의 열과 행을 사용하는 DataGridView것입니다.

속성

ContextMenuStrip	밴드의 바로 가기 메뉴를 가져오거나 설정합니다.
DataGridView	이 요소와 관련된 DataGridView 컨트롤을 가져옵니다. (다음에서 상속됨 DataGridViewElement)
DefaultCellStyle	밴드의 기본 셀 스타일을 가져오거나 설정합니다.
DefaultHeaderCellType	기본 머리글 셀의 런타임 형식을 가져오거나 설정합니다.
Displayed	밴드가 현재 화면에 표시되는지 여부를 나타내는 값을 가져옵니다.
Frozen	사용자가 DataGridView를 스크롤하면 밴드가 이동할지 여부를 나타내는 값을 가져오거나 설정합니다.
HasDefaultCellStyle	DefaultCellStyle 속성이 설정되었는지 여부를 나타내는 값을 가져옵니다.
HeaderCellCore	DataGridViewBand의 머리글 셀을 가져오거나 설정합니다.
Index	DataGridView 컨트롤에서 밴드의 상대적 위치를 가져옵니다.
InheritedStyle	스타일 상속을 고려하여 현재 밴드에 적용되는 셀 스타일을 가져옵니다.
IsRow	밴드가 행을 나타내는지 여부를 나타내는 값을 가져옵니다.
ReadOnly	사용자가 밴드의 셀을 편집할 수 있는지 여부를 나타내는 값을 가져오거나 설정합니다.
Resizable	UI(사용자 인터페이스)에서 밴드의 크기를 조정할 수 있는지 여부를 나타내는 값을 가져오거나 설정합니다.
Selected	밴드가 선택한 UI(사용자 인터페이스) 상태에 있는지 여부를 나타내는 값을 가져오거나 설정합니다.
State	요소의 UI(사용자 인터페이스) 상태를 가져옵니다. (다음에서 상속됨 DataGridViewElement)
Tag	밴드에 연결할 데이터가 포함된 개체를 가져오거나 설정합니다.
Visible	사용자에게 밴드를 표시할지 여부를 나타내는 값을 가져오거나 설정합니다.

메서드

Clone()	이 밴드와 정확하게 일치하는 복사본을 만듭니다.
Dispose()	DataGridViewBand에서 사용하는 모든 리소스를 해제합니다.
Dispose(Boolean)	DataGridViewBand에서 사용하는 관리되지 않는 리소스를 해제하고, 관리되는 리소스를 선택적으로 해제할 수 있습니다.
Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
Finalize()	밴드와 연결된 리소스를 해제합니다.
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
OnDataGridViewChanged()	밴드가 다른 DataGridView에 연결될 때 호출됩니다.
RaiseCellClick(DataGridViewCellEventArgs)	CellClick 이벤트를 발생시킵니다. (다음에서 상속됨 DataGridViewElement)
RaiseCellContentClick(DataGridViewCellEventArgs)	CellContentClick 이벤트를 발생시킵니다. (다음에서 상속됨 DataGridViewElement)
RaiseCellContentDoubleClick(DataGridViewCellEventArgs)	CellContentDoubleClick 이벤트를 발생시킵니다. (다음에서 상속됨 DataGridViewElement)
RaiseCellValueChanged(DataGridViewCellEventArgs)	CellValueChanged 이벤트를 발생시킵니다. (다음에서 상속됨 DataGridViewElement)
RaiseDataError(DataGridViewDataErrorEventArgs)	DataError 이벤트를 발생시킵니다. (다음에서 상속됨 DataGridViewElement)
RaiseMouseWheel(MouseEventArgs)	MouseWheel 이벤트를 발생시킵니다. (다음에서 상속됨 DataGridViewElement)
ToString()	현재 밴드를 나타내는 문자열을 반환합니다.
