GridView.OnSorted(EventArgs) 方法

定義

引發 Sorted 事件。Raises the Sorted event.

protected:
 virtual void OnSorted(EventArgs ^ e);
protected virtual void OnSorted (EventArgs e);
abstract member OnSorted : EventArgs -> unit
override this.OnSorted : EventArgs -> unit
Protected Overridable Sub OnSorted (e As EventArgs)

參數

e
EventArgs

包含事件資料的 EventArgsAn EventArgs that contains event data.

備註

Sorted當您按一下用來排序資料行的超連結時,但在控制項處理排序作業之後,就會引發此事件 GridViewThe Sorted event is raised when the hyperlink to sort a column is clicked, but after the GridView control handles the sort operation. 這可讓您在發生此事件時,提供執行自訂常式的事件處理方法,例如自訂排序。This enables you to provide an event-handling method that performs a custom routine, such as custom sorting, whenever this event occurs.

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.

OnSorted 方法也允許衍生類別處理事件,而不用附加委派。The OnSorted method also allows 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

當在衍生類別中覆寫 OnSorted(EventArgs) 時,請確定呼叫基底類別的 OnSorted(EventArgs) 方法,使已註冊的委派能接收到事件。When overriding OnSorted(EventArgs) in a derived class, be sure to call the base class's OnSorted(EventArgs) method so that registered delegates receive the event.
