BaseDataList.OnDataBinding(EventArgs) 方法

定义

引发 DataBinding 控件的 BaseDataList 事件。Raises the DataBinding event of a BaseDataList control.

protected:
 override void OnDataBinding(EventArgs ^ e);
protected override void OnDataBinding (EventArgs e);
override this.OnDataBinding : EventArgs -> unit
Protected Overrides Sub OnDataBinding (e As EventArgs)

参数

e
EventArgs

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

注解

当数据绑定到 BaseDataList 控件时,将引发 DataBinding 事件。The DataBinding event is raised when data is bound to the BaseDataList control. 此方法通知控件执行与其关联的任何数据绑定逻辑。This method notifies the control to perform any data-binding logic that is associated with it.

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.

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