finding the index of a datarow in the currencymanager

after much searching and reading many blogs and forums, i never found a comprehensive answer on the best way to get the index of a datarow from the currencymanager in vb.net. i found a few posts that led me in the right direction, not none that did exactly what i wanted. so this is what i came up with, i’m not sure if it’s the most efficient, but it seems to work.
