  • 참조

정의

네임스페이스:
System.Web.UI.WebControls
어셈블리:
System.Web.dll

TableCell에 있는 지정된 TableCellCollection의 인덱스를 나타내는 값을 반환합니다.

public:
 int GetCellIndex(System::Web::UI::WebControls::TableCell ^ cell);
public int GetCellIndex (System.Web.UI.WebControls.TableCell cell);
member this.GetCellIndex : System.Web.UI.WebControls.TableCell -> int
Public Function GetCellIndex (cell As TableCell) As Integer

매개 변수

cell
TableCell

TableCell에 있는 인덱스를 가져올 TableCellCollection입니다.

반환

Int32

TableCell 내에 있는 지정된 TableCellCollection의 인덱스를 반환합니다. 기본값은 -1로, 지정된 인덱스와 일치하지 셀이 없음을 나타냅니다.

예제

다음 예제에서는 사용 GetCellIndex 하는 방법에 설명 합니다 선택한 셀의 열 인덱스를 표시 하는 속성입니다.
