Stili e modelli di cornici
In questo argomento vengono descritti gli stili e i modelli per il controllo Frame. È possibile modificare il ControlTemplate predefinito per assegnare al controllo un aspetto univoco. Per altre informazioni, vedere Creare un modello per un controllo.
Componenti della cornice
Nella tabella seguente elenchiamo le parti denominate relative al controllo Frame.
| Parte | Digitare | Descrizione |
|---|---|---|
| PART_FrameCP | ContentPresenter | Area del contenuto. |
Stati frame
Nella tabella seguente sono elencati gli stati di visualizzazione per il controllo Frame.
| Nome dello stato visivo | Nome VisualStateGroup | Descrizione |
|---|---|---|
| Valido | Stati di Validazione | Il controllo utilizza la classe Validation e la proprietà associata Validation.HasError è false. |
| FuocoNonValido | Stati di Validazione | La proprietà associata Validation.HasError è true quando il controllo ha lo stato attivo. |
| InvalidoNonFocalizzato | StatiDiValidazione | La proprietà associata Validation.HasError è true il controllo non ha lo stato attivo. |
