How do I use an ASP.net asp:RangeValidator to validate a date properly?

<asp:TemplateField HeaderText="* License Setup Date">
    <EditItemTemplate>
        <asp:RequiredFieldValidator ID="LicenseSetupDateRequired"
            ErrorMessage="License Setup Date can't be blank."
            ValidationGroup="EditClientDetails"
            ControlToValidate="BeginDate"
            Text="*!"
            Display="Dynamic"
            runat="server"></asp:RequiredFieldValidator>
        <asp:RangeValidator ID="LicenseSetupDateRange"
            ErrorMessage="License Setup Date needs to be a date between 01/01/2000 and 12/31/2200"
            ValidationGroup="EditClientDetails"
            ControlToValidate="BeginDate"
            MinimumValue="01/01/2000"
            MaximumValue="12/31/2002"
            Type="Date"
            Text="*!" Display="Dynamic" runat="server"></asp:RangeValidator>
        <asp:TextBox ID="BeginDate" MaxLength="10"
            Text='<%# Bind("BeginDate", "{0:MM/dd/yyyy}") %>'
            runat="server"></asp:TextBox>
        <span class="fieldNote">(mm/dd/yyyy format)</span>
    </EditItemTemplate>
</asp:TemplateField>
