DataGridView.OnCellMouseMove(DataGridViewCellMouseEventArgs) Method


引发 CellMouseMove 事件。Raises the CellMouseMove event.

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



包含事件数据的 DataGridViewCellMouseEventArgsA DataGridViewCellMouseEventArgs that contains the event data.


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.

- 或 --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.


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.

OnCellMouseMove 方法还允许派生类对事件进行处理而不必附加委托。The OnCellMouseMove 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.

Notes to Inheritors

在派生类中重写 OnCellMouseMove(DataGridViewCellMouseEventArgs) 时,一定要调用基类的 OnCellMouseMove(DataGridViewCellMouseEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnCellMouseMove(DataGridViewCellMouseEventArgs) in a derived class, be sure to call the base class's OnCellMouseMove(DataGridViewCellMouseEventArgs) method so that registered delegates receive the event.
