DataGridView.OnCellValuePushed(DataGridViewCellValueEventArgs) DataGridView.OnCellValuePushed(DataGridViewCellValueEventArgs) DataGridView.OnCellValuePushed(DataGridViewCellValueEventArgs) DataGridView.OnCellValuePushed(DataGridViewCellValueEventArgs) Method

定义

引发 CellValuePushed 事件。Raises the CellValuePushed event.

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

参数

异常

eColumnIndex 属性值小于零或大于控件中的列数减一。The value of the ColumnIndex property of e is less than zero or greater than the number of columns in the control minus one.

-or- eRowIndex 属性值小于零或大于控件中的行数减一。The value of the RowIndex property of e is less than zero or 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.

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