Commenti

Importante

Per implementare la ricerca in un'app per Windows 10 o versione successiva, usare AutoSuggestBox. Per altre informazioni, vedi Casella di suggerimento automatico .

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

Nota

Un'app non può usare sia la casella di ricerca (Windows.UI.Xaml.Controls.SearchBox/WinJS.UI.SearchBox) che searchPane. L'uso della casella di ricerca e del riquadro di ricerca nella stessa app fa sì che l'app generi un'eccezione con questo messaggio: "Impossibile creare un'istanza di tipo 'Windows.UI.Xaml.Controls.SearchBox'".

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