Our customer, the US Air Force, wants to enter dates using the standard military date format of dd-MMM-yyyy (ex 01-MAY-2008).  This is not an option in the drop down for the MaskInput property and when I type it in dd-MMM-yyyy in the MaskInput property it is displayed in the text area.  When the application runs the user cannot manually enter any dates nor can they select a date from the calendar.  How do I implement this?

 Thanks
