ListView.OnItemActivate(EventArgs) 方法

定义

引发 ItemActivate 事件。Raises the ItemActivate event.

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

参数

e
EventArgs

包含事件数据的 EventArgsAn EventArgs that contains the event data.

注解

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息,请参阅处理和引发事件For more information, see Handling and Raising Events.

OnItemActivate 方法还允许派生类对事件进行处理而不必附加委托。The OnItemActivate method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

在派生类中重写 OnItemActivate(EventArgs) 时,一定要调用基类的 OnItemActivate(EventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnItemActivate(EventArgs) in a derived class, be sure to call the base class's OnItemActivate(EventArgs) method so that registered delegates receive the event.
