I just spent a solid hour figuring this out, so I figured I would post it here in case it helps anybody.
If you want to write a client side method for a relationship grid event (onSelectRow,onInsertRow,onDeleteRow) and access elements on the Item's Form then here is the trick: The Form's DOM (document) object can be found by:
parent.parent.frames[1].document
I hope that helps somebody out!
