편집이 허용되는 상태로 그리드를 넣으려고 시도합니다.

public:
 virtual bool BeginEdit(System::Windows::Forms::DataGridColumnStyle ^ gridColumn, int rowNumber);
public bool BeginEdit(System.Windows.Forms.DataGridColumnStyle gridColumn, int rowNumber);
abstract member BeginEdit : System.Windows.Forms.DataGridColumnStyle * int -> bool
override this.BeginEdit : System.Windows.Forms.DataGridColumnStyle * int -> bool
Public Function BeginEdit (gridColumn As DataGridColumnStyle, rowNumber As Integer) As Boolean

매개 변수

gridColumn
DataGridColumnStyle

편집할 A DataGridColumnStyle 입니다.

rowNumber
Int32

편집할 행의 수입니다.

반품

Boolean

해당 메서드에 성공하면 true이고, 그렇지 않으면 false입니다.

구현

BeginEdit(DataGridColumnStyle, Int32)

예제

다음 코드 예제에서는 메서드를 BeginEdit 사용 하 여 지정 된 열 및 행을 변경 하기 전에 편집 가능한 경우 테스트 합니다.
