I'm trying to add a data validator to ensure the date entered is today or later. I am using the following:

<asp:CompareValidator id=c1 
ValueToCompare='<%# DateTime.Today.ToShortDateString() %>' 
ControlToValidate="estJobDate" Operator="GreaterThanEqual" Type="Date" Text="*" runat="server" />

But this validator fires as I instantiate the screen before the user has entered data - so obviously I'm missing something.

TIA,
Doug
