Raises the MouseDown event.

protected:
 virtual void OnMouseDown(System::Windows::Forms::MouseEventArgs ^ e);

protected virtual void OnMouseDown (System.Windows.Forms.MouseEventArgs e);

abstract member OnMouseDown : System.Windows.Forms.MouseEventArgs -> unit
override this.OnMouseDown : System.Windows.Forms.MouseEventArgs -> unit

Protected Overridable Sub OnMouseDown (e As MouseEventArgs)

Parameters

e: MouseEventArgs

A MouseEventArgs that contains the event data.

Remarks

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.

Notes to Inheritors

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.
