ItemsControl.GroupStyle 속성

정의

네임스페이스:

System.Windows.Controls

어셈블리:

PresentationFramework.dll

각 그룹 수준의 모양을 정의하는 GroupStyle 개체의 컬렉션을 가져옵니다.

public:
 property System::Collections::ObjectModel::ObservableCollection<System::Windows::Controls::GroupStyle ^> ^ GroupStyle { System::Collections::ObjectModel::ObservableCollection<System::Windows::Controls::GroupStyle ^> ^ get(); };

public System.Collections.ObjectModel.ObservableCollection<System.Windows.Controls.GroupStyle> GroupStyle { get; }

member this.GroupStyle : System.Collections.ObjectModel.ObservableCollection<System.Windows.Controls.GroupStyle>

Public ReadOnly Property GroupStyle As ObservableCollection(Of GroupStyle)

속성 값

ObservableCollection<GroupStyle>

각 그룹 수준의 모양을 정의하는 GroupStyle 개체의 컬렉션입니다.

예제

다음 예제에서는 XmlDataProvider 바인딩된 ItemsControl 그룹화 추가 및 제거 논리를 포함하는 코드 숨김 콘텐츠를 보여 줍니다. 확인란을 선택하면 ItemsControl 내용이 Type 특성별로 그룹화됩니다.

각 그룹은 CollectionViewGroup형식입니다. GroupStyle HeaderTemplate 각 그룹의 Name 표시하는 TextBlock 표시되도록 지정됩니다. 이 경우 NameWork 또는 Home.

설명

인덱스 0의 항목은 최상위 그룹을 설명하고 인덱스 1의 항목은 다음 수준을 설명합니다. 컬렉션의 항목보다 그룹화 수준이 더 많은 경우 마지막 항목이 추가 수준에 사용됩니다.
