定义

命名空间:
System.Windows.Forms
程序集:
System.Windows.Forms.dll

引发 ColumnDataPropertyNameChanged 事件。Raises the ColumnDataPropertyNameChanged event.

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

参数

e
DataGridViewColumnEventArgs

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

异常

ArgumentException

由 e 的 Column 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.

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