定义

引发 CancelRowEdit 事件。Raises the CancelRowEdit event.

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

参数

e
QuestionEventArgs

包含事件数据的 QuestionEventArgsA QuestionEventArgs 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.

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