DataGridViewCell.FormattedValueType 속성

정의

네임스페이스:

System.Windows.Forms

어셈블리:

System.Windows.Forms.dll

셀과 연결된 형식이 지정된 값의 형식을 가져옵니다.

public:
 virtual property Type ^ FormattedValueType { Type ^ get(); };

[System.ComponentModel.Browsable(false)]
public virtual Type FormattedValueType { get; }

[<System.ComponentModel.Browsable(false)>]
member this.FormattedValueType : Type

Public Overridable ReadOnly Property FormattedValueType As Type

속성 값

Type

셀의 형식이 지정된 값에 대한 형식을 나타내는 Type 입니다.

특성

BrowsableAttribute

예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 FormattedValueType 셀 내용의 형식을 확인 하는 속성입니다. 이 예제는 FormattedValueType 속성 셀에 포함 되어 있는지 확인 하는 데 사용 됩니다는 String 값으로 변환 하기 전에 합니다. 이 예제는에서 사용할 수 있는 보다 큰 예제의 일부는 DataGridView.SelectionChanged 이벤트입니다.

설명

속성은 Value 셀에 포함된 실제 데이터 개체인 반면 FormattedValue 속성은 데이터의 형식이 지정된 표현입니다. 합니다 ValueType 및 FormattedValueType 속성 데이터 형식의 이러한 값은 각각에 해당 합니다.
