expirationdropdownvalidator doesn't work

[jtry]

The cb:expirationdropdownvalidator in my CreditCardPaymentForm never work.

Here is the code,

<asp:dropdownlist ID="ExpirationMonth" runat="server" ValidationGroup="CreditCard">
<asp:ListItem Text="Month" Value=""></asp:ListItem>
<asp:ListItem Value="01">01</asp:ListItem>
<asp:ListItem Value="02">02</asp:ListItem>
<asp:ListItem Value="03">03</asp:ListItem>
<asp:ListItem Value="04">04</asp:ListItem>
<asp:ListItem Value="05">05</asp:ListItem>
<asp:ListItem Value="06">06</asp:ListItem>
<asp:ListItem Value="07">07</asp:ListItem>
<asp:ListItem Value="08">08</asp:ListItem>
<asp:ListItem Value="09">09</asp:ListItem>
<asp:ListItem Value="10">10</asp:ListItem>
<asp:ListItem Value="11">11</asp:ListItem>
<asp:ListItem Value="12">12</asp:ListItem>
</asp:dropdownlist>
<asp:RequiredFieldValidator ID="MonthValidator" runat="server" ErrorMessage="You must select the expiration month." ControlToValidate="ExpirationMonth" Display="Static" Text="*" ValidationGroup="CreditCard"></asp:RequiredFieldValidator>
<asp:dropdownlist ID="ExpirationYear" Runat="server" ValidationGroup="CreditCard">
<asp:ListItem Text="Year" Value=""></asp:ListItem>
</asp:dropdownlist>
<cb:expirationdropdownvalidator ID="ExpirationDropDownValidator1" runat="server"
Display="Dynamic" errormessage="You must enter an expiration date in the future."
monthcontroltovalidate="ExpirationMonth" yearcontroltovalidate="ExpirationYear"
Text="*" ValidationGroup="CreditCard"></cb:expirationdropdownvalidator>
<asp:RequiredFieldValidator ID="YearValidator" runat="server" ErrorMessage="You must select the expiration year."
ControlToValidate="ExpirationYear" Display="Static" Text="*" ValidationGroup="CreditCard"></asp:RequiredFieldValidator>

All other validators are working fine, only the expirationdropdownvalidator never work. If I selected a date before current date, nothing happens, and the form continue to checkout.

What's wrong with it? Thanks a lot!
