Assembly: System.Windows.Forms (in system.windows.forms.dll)
A MouseEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnMouseMove 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.
Do not call OnMouseMove if the button is disabled (this includes calls to the base class's OnMouseMove method when you override OnMouseMove in a derived class). When disabling the button in an override of OnMouseMove, call the base class's OnMouseMove method before disabling the button, or do not call it at all.
