Importante

Per implementare la ricerca in un'app per Windows 10 o versioni successive, usare AutoSuggestBox. Per altre informazioni, vedere Casella di suggerimento automatico .

Non è consigliabile usare API Windows.ApplicationModel.Search (SearchPane, SearchContract) o SearchBox nelle app per Windows 10 o versioni successive.

Nota

Un'app non può usare la casella di ricerca (Windows.UI.Xaml.Controls.SearchBoxWinJS.UI.SearchBox/) e SearchPane. Usando sia la casella di ricerca che il riquadro di ricerca nella stessa app, l'app genera un'eccezione con questo messaggio: "Impossibile creare un'istanza di tipo 'Windows.UI.Xaml.Controls.SearchBox'"

Registrare per ricevere una notifica quando questo evento viene generato aggiungendo un listener eventi al searchPane e assegnando una funzione gestore per l'evento. È possibile accedere alle informazioni sull'evento con l'oggetto searchPaneVisibilityChangedEventArgs passato al gestore eventi.
