TableItemPattern.TableItemPatternInformation.RowSpan 속성

정의

네임스페이스:

System.Windows.Automation

어셈블리:

UIAutomationClient.dll

테이블 셀 또는 항목의 범위에 포함되는 행 수를 가져옵니다.

public:
 property int RowSpan { int get(); };

public int RowSpan { get; }

member this.RowSpan : int

Public ReadOnly Property RowSpan As Integer

속성 값

Int32

범위에 포함되는 열 수입니다. 기본값은 1입니다.

예제

다음 예제에서는 AutomationFocusChangedEvent 테이블 컨테이너 내에서 테이블 항목의 이동을 추적 하려면 수신기를 선언 합니다. 항목 속성 포커스 변경 이벤트가 발생할 때마다 기록 됩니다.
