Great! Except, what does that mean? If I had read that in the documentation (blushing for not having done so), I'm not sure what that means exactly ... Does that mean that my class needs a When and Valid method defined? And can then be empty, or can they just have a comment, or what?

Thanks in advance,

>>This works for six of the eight events. That is, I can verify that the method in the grid is invoked as expected, except for Valid and When.
