DetailsViewInsertEventArgs.Values 속성

정의

삽입할 레코드에 대한 필드 이름/값 쌍이 들어 있는 사전을 가져옵니다.

public:
 property System::Collections::Specialized::IOrderedDictionary ^ Values { System::Collections::Specialized::IOrderedDictionary ^ get(); };
public System.Collections.Specialized.IOrderedDictionary Values { get; }
member this.Values : System.Collections.Specialized.IOrderedDictionary
Public ReadOnly Property Values As IOrderedDictionary

속성 값

IOrderedDictionary

삽입할 레코드에 대한 키 필드 이름/값 쌍의 사전이 들어 있는 IOrderedDictionary입니다.

예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 Values 삽입 되는 레코드에 대 한 필드의 값에 액세스 하는 속성입니다.

설명

사용 된 Values 삽입할 레코드에 대 한 필드의 값에 액세스 하는 속성입니다. 예를 들어 수 레코드의 값을 HTML로 인코딩하는 데이터 소스에 삽입 하기 전에.

Values 속성은 IOrderedDictionary 인터페이스를 구현하는 개체를 반환합니다. 개체에 DictionaryEntry 레코드의 필드를 나타내는 개체입니다.

참고

인덱스를 이용할 수 있습니다 가기로 IOrderedDictionary 직접 값 필드에 액세스 하는 개체입니다.
