I have a infragistics WebDateChooser:

<igsch:WebDateChooser Section508Compliant="true" ID="dateDepartureDate" runat="server"
       NullDateLabel="" Value="" TabIndex="7" CalendarLayout-HideOtherMonthDays="true" >
<CalendarLayout>
                                   
</CalendarLayout>

</igsch:WebDateChooser>

Even though you can't choose a previous date in the drop down calender (in Page_load in code behind I did dateDepartureDate.MinDate = System.DateTime.Today), I still want all previous days of the current month to be grayed out so that it's obvious they cannot be clicked.  How can I gray them out?  Please let me know.  Thanks.
