Assembly: System.Windows.Forms (in system.windows.forms.dll)
This method is called by the parent form to notify the Button that it should be set as the default button and to allow it to adjust its appearance accordingly. Typically, a button that is the default button for a form has a thicker border than other buttons on the form.
Calling the NotifyDefault method only draws the button as a default button; it does not change its behavior. To make the button behave like a default button, it must be assigned to the AcceptButton property of the Form.Notes to Inheritors When overriding NotifyDefault in a derived class, be sure to call the base class's NotifyDefault method.
