注解

重要

若要在应用中实现Windows 10或更高版本的搜索，请使用 AutoSuggestBox。 有关详细信息 ，请参阅自动建议框 。

不应在 Windows 10 或更高版本的应用中使用 Windows.ApplicationModel.Search API (SearchPane、 SearchContract) 或 SearchBox API。

注意

应用不能同时使用搜索框 (Windows.UI.Xaml.Controls.SearchBox/WinJS.UI.SearchBox) 和 SearchPane。 在同一应用中同时使用搜索框和搜索窗格会导致应用引发异常，并显示以下消息：“无法创建'Windows.UI.Xaml.Controls.SearchBox'类型的实例。”

注册以在触发此事件时收到通知，方法是将事件侦听器添加到 searchPane 并为事件分配处理程序函数。 可以使用传递给事件处理程序的 searchPaneVisibilityChangedEventArgs 对象访问有关事件的信息。
