String was not recognized as a valid DateTime.

(ddYear.SelectedItem.Text + ddMonth.SelectedItem.Text + ddDay.SelectedItem.Text)

on my function I referenced as this
 public static int CreateNewUser( string DOB)
newUser.DOB = DateTime.Parse(DOB);

giving me error saying String was not recognized as a valid DateTime.

Try this:
public static int CreateNewUser( string DOB)
     newUser.DOB = DateTime.ParseExact(DOB, "yyyyMMdd", System.Globalization.CultureInfo.InvariantCulture);

Open in new window


DateTime.Parse tries to guess the date format of the string, when it cannot it fails.  That's why it works some times.
