ButtonColumn.DataTextField 속성

정의

ButtonColumn 개체에 바인딩할 데이터 소스의 필드 이름을 가져오거나 설정합니다.

public:
 virtual property System::String ^ DataTextField { System::String ^ get(); void set(System::String ^ value); };
public virtual string DataTextField { get; set; }
member this.DataTextField : string with get, set
Public Overridable Property DataTextField As String

속성 값

String

ButtonColumn에 바인딩할 필드 이름입니다. 기본값은 빈 문자열("")입니다.

예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 DataTextField 바인딩할 속성을 ButtonColumn 개체 데이터 소스의 필드.

설명

사용 하 여는 DataTextField 속성에 바인딩할 데이터 소스의 필드 이름을 지정 하는 Text 속성에 있는 단추는 ButtonColumn 개체.

직접 설정 하는 대신 필드에 열을 바인딩하는 Text 속성을 사용 하면 다른 캡션 단추에 표시할 수 있습니다는 ButtonColumn 지정된 된 필드에 값을 사용 하 여 합니다.

이 속성의 값은 뷰 상태에 저장 됩니다.
