Validate Wizard first step 1st

I have a Wizard that the user is to enter their password. If the password is correct then they can move to the next step. If not stay at 1st step.

Here is the code for the Next Button Click.

 1 protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e)
2 {
3 userIsValidated = Membership.ValidateUser(Session["username"].ToString(), authenticationPassword.Text.ToString());
4 e.Cancel = !userIsValidated;
5 }
