DataGridCell.OnUnselected(RoutedEventArgs) 方法

定義

引發 Unselected 事件。Raises the Unselected event.

protected:
 virtual void OnUnselected(System::Windows::RoutedEventArgs ^ e);
protected virtual void OnUnselected (System.Windows.RoutedEventArgs e);
abstract member OnUnselected : System.Windows.RoutedEventArgs -> unit
override this.OnUnselected : System.Windows.RoutedEventArgs -> unit
Protected Overridable Sub OnUnselected (e As RoutedEventArgs)

參數

e
RoutedEventArgs

事件的資料。The data for the event.

備註

引發事件會透過委派叫用此事件處理常式。Raising an event invokes the event handler through a delegate. 如需詳細資訊,請參閱 處理和引發事件For more information, see Handling and Raising Events.

OnUnselected方法也可讓衍生類別處理事件,而不需要附加委派。The OnUnselected method also enables derived classes to handle the event without attaching a delegate. 這是在衍生類別中處理事件的慣用技巧。This is the preferred technique for handling the event in a derived class.

給繼承者的注意事項

OnUnselected(RoutedEventArgs)在衍生類別中覆寫時,請務必呼叫基類的 OnUnselected(RoutedEventArgs) 方法,讓已註冊的委派能接收事件。When overriding OnUnselected(RoutedEventArgs) in a derived class, make sure that you call the base class' OnUnselected(RoutedEventArgs) method so that registered delegates receive the event.
