DataGridViewCellValueEventArgs.RowIndex 속성

정의

이벤트가 발생하는 셀의 행 인덱스를 나타내는 값을 가져옵니다.Gets a value indicating the row index of the cell that the event occurs for.

public:
 property int RowIndex { int get(); };
public int RowIndex { get; }
member this.RowIndex : int
Public ReadOnly Property RowIndex As Integer

속성 값

이벤트가 발생하는 셀이 포함된 행의 인덱스입니다.The index of the row containing the cell that the event occurs for.

예제

다음 코드 예제에서는 처리 된 CellValuePushed 데이터 저장소 개체에 업데이트 및 새 항목을 저장 하는 이벤트입니다.The following code example handles the CellValuePushed event to store updates and new entries in a data store object. 이 예제는에서 사용할 수 있는 보다 큰 예제의 일부는 DataGridView.VirtualMode 참조 항목입니다.This example is part of a larger example available in the DataGridView.VirtualMode reference topic.
