Generating event handler in VS2008

I am trying to generate an event handler in windows form application. When I write 

myAlgorithm.nextNodeFound +=

and press 'Tab' two times it generates a new handler automatically but this handler works on EventArgs, what I need is to have a handler that works with CustomEventArgs. I tried to modify the signature of auto generated handler but then it gives the error

*No overload for myAlgo_nextNodeFound matches delegate System.EventHandler*

Please suggest how to make it work.

It looks like the problem is that you've declared your nextNodeFound event to be of type EventHandler. If you need it to work with your custom args, you should use a delegate type which uses the right parameters... the generic EventHandler<TEventArgs> type is probably what you want:

public event EventHandler<CustomEventArgs> NextNodeFound;

Note that I've changed the name of the comply with .NET naming conventions. This is also assuming that CustomEventArgs derives from EventArgs - if it doesn't already, I suggest you make it do so. You might also want to change the name to indicate how it's custom - such as NodeTraversalEventArgs or something similar.

It sounds like you may be relatively new to .NET events - you might want to read my article on events and delegates.
