If the current form or one of its parents is disposing of resources, the Form.OnRightToLeftLayoutChanged(EventArgs) method will return without performing any action. If the Control.RightToLeft property of the form has a value of RightToLeft.Yes, then the handles of the form and its child controls will be recreated through calls to the Control.RecreateHandle method.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The Form.OnRightToLeftLayoutChanged(EventArgs) 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.
