protected:
override void OnMouseDown(System::Windows::Forms::MouseEventArgs ^ e);
protected override void OnMouseDown (System.Windows.Forms.MouseEventArgs e);
override this.OnMouseDown : System.Windows.Forms.MouseEventArgs -> unit
Protected Overrides Sub OnMouseDown (e As MouseEventArgs)
A MouseEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnMouseDown method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
When overriding OnMouseDown(MouseEventArgs) in a derived class, be sure to call the base class's OnMouseDown(MouseEventArgs) method so that registered delegates receive the event.
