DataGrid.AllowNavigation 속성

  • 아티클

탐색이 허용되는지 여부를 나타내는 값을 가져오거나 설정합니다.

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

구문

‘선언
Public Property AllowNavigation As Boolean
‘사용 방법
Dim instance As DataGrid
Dim value As Boolean

value = instance.AllowNavigation

instance.AllowNavigation = value

public bool AllowNavigation { get; set; }

public:
property bool AllowNavigation {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_AllowNavigation ()

/** @property */
public void set_AllowNavigation (boolean value)

public function get AllowNavigation () : boolean

public function set AllowNavigation (value : boolean)

속성 값

탐색이 허용되면 true이고, 그렇지 않으면 false입니다. 기본값은 true입니다.

설명

이 속성이 false로 설정되면 자식 테이블에 대한 링크가 표시되지 않습니다.

예제

다음 코드 예제에서는 AllowNavigation 속성을 true와 false 사이에서 전환합니다.
