Probably you don't understand something very basic and fundamental. You cannot directly "raise event", unless the event instance is declared in the same class where you want to invoke it; you cannot invoke an event even in a derived class. As the class DataGridView is the code from .NET FCL, you cannot invoke that event at all. This is a very important fool-proof feature of .NET. You never really need to invoke those events; they are no designed for that. You can only handle the event. The even will be invoked in this class when you actually change the content of any cell, but that cannot be a problem, right? :-)
