Hi Rodney,

Try changing the format of the date to YYYY/MM/DD instead for the MinimumValue and MaximumValue. There could be an interpretation issue with the culture. The YYYY/MM/DD format is culture-neutral.

I have three different validation controls validating the amount field, but I can't seem to get a range validator working for the calendar control. I have embedded the range validator in the edit template of the column template for the calendar. I keep getting an error which says the date value cannot be converted to the date data type for maximum value parameter of the range validator control.
