title: CreateUserWizard step changing issue after account creation
body: <p>I want to change the createuserwizard.step= start if the mail sending fails and not to go to successful creation step.</p>
  
  <pre><code>                 catch (SmtpException ex)
      {
         Membership.DeleteUser(textboxemail.Text.Trim());
         Literal errorMessage=(Literal) CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("ErrorMessage");
         errorMessage.Text = "Account creation failed due to email notification."+ ex.Message + " errorcode" +ex.StatusCode + "; inner exception; " + ex.InnerException;
         CreateUserWizard1.CreateUserStep.StepType = WizardStepType.Start;
      }
  </code></pre>
  
  <p>but the exception says the steptype can't be changed. So how to do this. I mean to stop from going to success step. </p>
