DataGridView.OnRowErrorTextChanged(DataGridViewRowEventArgs) 方法

定义

引发 RowErrorTextChanged 事件。Raises the RowErrorTextChanged event.

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

参数

e
DataGridViewRowEventArgs

包含事件数据的 DataGridViewRowEventArgsA DataGridViewRowEventArgs that contains the event data.

异常

eRow 属性指示的行不属于此 DataGridView 控件。The row indicated by the Row 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.

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