DataGridView.OnCellFormatting(DataGridViewCellFormattingEventArgs) 方法

定义

引发 CellFormatting 事件。Raises the CellFormatting event.

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

参数

异常

eColumnIndex 属性值大于控件中的列数减一。The value of the ColumnIndex property of e is greater than the number of columns in the control minus one.

-or- eRowIndex 属性值大于控件中的行数减一。The value of the RowIndex property of e is greater than the number of rows in the control minus one.

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.

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