I have two date fields PayPeriodStartDP and PayPeriodEndDP. I want them
both to start with null values. When the user changes the
PayPeriodStartDP value, i want to make sure the start date is greater
than the end date. I have set both date controls to EnableNullValue and
IsNullDate to true. But if i check the value for each date before i
enter anything into them, i find them both set to the current date. How
do i get a true null value or check to see if the user has not enter a
date yet into the controls?
