열을 가로로 스크롤할 수 없는지 여부를 나타내는 값을 가져옵니다.

public:
 property bool IsFrozen { bool get(); };

public bool IsFrozen { get; }

member this.IsFrozen : bool

Public ReadOnly Property IsFrozen As Boolean

속성 값

Boolean

열을 가로로 스크롤할 수 없으면 true이고, 그렇지 않으면 false입니다. 등록된 기본값은 false입니다. 값에 영향을 줄 수 있는 요소에 대한 자세한 내용은 DependencyProperty를 참조하십시오.

설명

IsFrozen 열 고정을 사용할 수 없습니다. 대신, 설정 된 FrozenColumnCount 속성입니다. 최대 지정 된 열 맨 왼쪽 열은 FrozenColumnCount 번호 위치에 고정 됩니다.
