Raises the ComponentChanging event.
Assembly: System (in System.dll)
Use the method to send notification that an instance of an object is about to be changed. This method also returns a value indicating whether this object can be changed. When false is returned, do not change the object.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The 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 in a derived class, be sure to call the base class’s method so that registered delegates receive the event.
