Hi All,

I have 3 classes. class A, B and C. with all 3 classes having the event OnSomethingHappend.
A.OnSomethingHappend, B.OnSomethingHappend and C.OnSomethingHappend

C had a member of type B
B has a member of type A

So:
C
  B
    A

How can i chain the event OnSomethingHappend from A all the way to C via B
So that if the event fires in a it is automaticly bubled up to C and fires there aswell.

I want to bind the events somehow rather then passing on the event.
S0 what i dont want to do is create an event handler in class C that responds to the event in class B that is fired when the event in class A happens.

So code i dont want to use is like this for
class C
B.OnSomethingHappend += new B.SomethingHappend(_B_OnSomethingHappend);

void _B_OnSomethingHappend(object sender, EventArgs eventArgs)
{
            //do stuff when event in class A fired
}

Class B
A.OnSomethingHappend += new A.SomethingHappend(_A_OnSomethingHappend);

void _A_OnSomethingHappend(object sender, EventArgs eventArgs)
{
            OnSomethingHappend(this, new EventArgs());
}

Is there a more cleaner way to bind/chain events?
