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

参数

e

包含事件数据的 DataGridViewColumnEventArgsA DataGridViewColumnEventArgs that contains the event data.

异常

eColumn 属性指示的列不属于此 DataGridView 控件。The column indicated by the Column property of e does not belong to this DataGridView control.

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.

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