I have this compare validator:
<asp:CompareValidator ID="cpvBirthDate" Type="Date" ControlToValidate="txtBirthDate" Operator="DataTypeCheck" runat="server" ErrorMessage="Please enter a valid date in this format mm-dd-yy">
<img src="Images/ExclamationMark.gif" alt="Please enter a valid date in this format mm-dd-yy" />
</asp:CompareValidator>
It works on the clientside fine, but if a user has javascript disabled then it accepts 071873 which is not a date. Do I need to write a specific serverside function for this validator to work?
