DataGridViewCellCollection.OnCollectionChanged(CollectionChangeEventArgs) 方法

定义

引发 CollectionChanged 事件。Raises the CollectionChanged event.

protected:
 void OnCollectionChanged(System::ComponentModel::CollectionChangeEventArgs ^ e);
protected void OnCollectionChanged (System.ComponentModel.CollectionChangeEventArgs e);
member this.OnCollectionChanged : System.ComponentModel.CollectionChangeEventArgs -> unit
Protected Sub OnCollectionChanged (e As CollectionChangeEventArgs)

参数

e
CollectionChangeEventArgs

包含事件数据的 CollectionChangeEventArgsA CollectionChangeEventArgs 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.

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