ListView — Style i szablony

  • Artykuł

W tym temacie opisano style i szablony kontrolki ListView . Możesz zmodyfikować wartość domyślną ControlTemplate , aby nadać kontrolce unikatowy wygląd. Aby uzyskać więcej informacji, zobacz Tworzenie szablonu dla kontrolki.

Części ListView

Kontrolka ListView nie ma żadnych nazwanych części.

Podczas tworzenia ControlTemplate elementu dla ListViewelementu szablon może zawierać element ItemsPresenter w obiekcie ScrollViewer. (Obiekt ItemsPresenter wyświetla każdy element w elemencie ListView; ScrollViewer włącza przewijanie w kontrolce). Jeśli element ItemsPresenter nie jest bezpośrednim elementem podrzędnym ScrollViewerelementu , musisz podać ItemsPresenter nazwę . ItemsPresenter

Stany listView

W poniższej tabeli wymieniono stany wizualizacji dla kontrolki ListView .

Nazwa wizualizacji Nazwa grupy VisualStateGroup opis
Prawidłowe ValidationStates Kontrolka Validation używa klasy , a Validation.HasError dołączona właściwość to false.
Nieprawidłowy fokos ValidationStates Dołączona Validation.HasError właściwość ma true fokus kontrolki.
InvalidUnfocused ValidationStates Dołączona Validation.HasError właściwość ma true kontrolkę nie ma fokusu.
