NumericUpDown.DecimalPlaces 속성

스핀 상자(up-down 컨트롤이라고도 함)에 표시할 소수 자릿수를 가져오거나 설정합니다.

네임스페이스: System.Windows.Forms
어셈블리: System.Windows.Forms(system.windows.forms.dll)

구문

‘선언
Public Property DecimalPlaces As Integer
‘사용 방법
Dim instance As NumericUpDown
Dim value As Integer

value = instance.DecimalPlaces

instance.DecimalPlaces = value

public int DecimalPlaces { get; set; }

public:

    int get ();
    void set (int value);

속성 값

스핀 상자에 표시할 소수 자릿수입니다. 기본값은 0입니다.

예외

예외 형식	조건
ArgumentOutOfRangeException	할당된 값이 0보다 작은 경우 - 또는 - 할당된 값이 99보다 큰 경우

설명

DecimalPlaces 속성이 설정되어 있으면 UpdateEditText 메서드가 호출되어 스핀 상자 표시를 새로운 형식으로 업데이트합니다.

적절한 소수점 기호는 해당 운영 체제의 국가별 설정에서 결정됩니다.

예제

다음 코드 예제에서는 NumericUpDown 컨트롤을 만들어 초기화하고 해당 공용 속성 중 일부를 설정한 다음 사용자가 런타임에 이러한 속성 중 일부를 변경할 수 있도록 합니다. 이 코드는 세 개의 CheckBox 컨트롤이 폼에 배치되고 Click 이벤트에 대한 처리기가 인스턴스화된 것으로 가정합니다. DecimalPlaces, ThousandsSeparator 및 Hexadecimal 속성은 각 확인란의 Click 이벤트에 대해 설정됩니다.
