DisplayModeFormat="MM/dd/yy"

If I load the control and then save back, the control looses the complete year info, i.e. 2008 turns into just 8 and throughs an invalid date error. I know the industry has decided that everybody wants to use 4 digit years, but I find it just as much of a waste of real estate now as I did before the millenium. Can I do this or is the control unable to work with 2 digit years?

Thanks for anyone's help.
