Can you elaborate more?
Windows Forms, Web Forms, or WPF?

C#

DateTime dob = DateTime.Now;
string dobStr = dob.ToString("MMddyy");
if (idNumber.StartsWith(dobStr))
{
    // we have a match - do something
}

You'll have to change the ToString parameter if your ID numbers use the month/day/year in a different order.

In order to validate this, you'll need a custom validator (on a web form).

If i am not wrong then you want server side validation OnClick event of button and it's validate then redirect to second page otherwise show an validation message.

If i m right then.....

OnClick event of button execute select statement with ID and data field entered by user and if any row fount the redirect to next page or whatever you want otherwise show validation message in label.............
