grid row onBlur

Is there an event I can attach to that will detect when a row loses focus? I guess like an onBlur for a row and it passes me the id of the row that lost focus?

There is no such event.
If by focus you mean selection, the onSelectStateChanged event can be used for such task
If by focus you mean - currently edited item, you can use onEditCell event which occurs when edit operation started ( stage 1) or finished ( stage 2 )
