Is there a validation expression or any other way to check a birthdate entered to ensure the date entered makes the person "at least xx years of age" as of the current date? We have a registration form that asks the birthdate and we need to have a date validation that 'error messages' the user if they are under the minimum age.

I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>

<asp:Image ID="Image" runat="server" ImageUrl ='<%#Eval("UserId","Image.aspx?UserId={0}") %>'
Following is the successful code behind for the page image.aspx referred to above (page = image.aspx.vb):

The user is not required to submit an entry daily, but is allowed to go back and submit when they have extra time to do so. I would like to display the next day from last date recorded in the SQL Table as a session variable, so when they go to the form to submit, the last necessary date is shown and the user knows where they left off.
