DataGridView.OnRowPrePaint(DataGridViewRowPrePaintEventArgs) 方法

定义

引发 RowPrePaint 事件。Raises the RowPrePaint event.

protected public:
 virtual void OnRowPrePaint(System::Windows::Forms::DataGridViewRowPrePaintEventArgs ^ e);
protected internal virtual void OnRowPrePaint (System.Windows.Forms.DataGridViewRowPrePaintEventArgs e);
abstract member OnRowPrePaint : System.Windows.Forms.DataGridViewRowPrePaintEventArgs -> unit
override this.OnRowPrePaint : System.Windows.Forms.DataGridViewRowPrePaintEventArgs -> unit
Protected Friend Overridable Sub OnRowPrePaint (e As DataGridViewRowPrePaintEventArgs)

参数

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.

OnRowPrePaint 方法还允许派生类对事件进行处理而不必附加委托。The OnRowPrePaint 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 OnRowPrePaint(DataGridViewRowPrePaintEventArgs) 时,请确保调用基类 "OnRowPrePaint(DataGridViewRowPrePaintEventArgs) 方法,以便注册的委托接收事件。When overriding OnRowPrePaint(DataGridViewRowPrePaintEventArgs) in a derived class, be sure to call the base class' OnRowPrePaint(DataGridViewRowPrePaintEventArgs) method so that registered delegates receive the event.
