LoginView.OnInit(EventArgs) 方法

定义

引发 Init 事件。Raises the Init event.

protected public:
 override void OnInit(EventArgs ^ e);
protected internal override void OnInit (EventArgs e);
override this.OnInit : EventArgs -> unit
Protected Friend Overrides Sub OnInit (e As EventArgs)

参数

e
EventArgs

包含事件数据的 EventArgs 对象。An EventArgs object that contains the event data.

注解

OnInit方法执行控件的初始化 LoginViewThe OnInit method performs initialization for the LoginView control.

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.

OnInit 方法还允许派生类对事件进行处理而不必附加委托。The OnInit 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 OnInit(EventArgs) 时,一定要调用基类的 OnInit(EventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnInit(EventArgs) in a derived class, be sure to call the base class's OnInit(EventArgs) method so that registered delegates receive the event.
