Message to user when email not unique?

[kbalias]

Hi I am using Visual Web Developer 2010 Express (with C# as code-behind) to develop a website. I have created a custom MembershipProvider and I have specified that in the web.config that requiresUniqueEmail="true". In the CreateUser() method I check whether the email that the new user has entered is unique and the code works. How do I then display a message to the user in the CreateUserWizard if the email he has entered is not unique? I thought I could reference the CreateUserWizard in the CreateUser() method, but the following does not work:

Label labelDuplicateEmail = (Label)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("LabelDuplicateEmail");
labelDuplicateEmail.Text = "Email already exists in the database.";

All help will be appreciated. Kobus

Hi I have managed to figure it out. I am using the CreateUserError event of the CreateUserWizard.

protected void RegisterUser_CreateUserError(object sender, CreateUserErrorEventArgs e)
{
Label labelDuplicateEmail = (Label)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("LabelDuplicateEmail");
labelDuplicateEmail.Text = string.Empty;

if (e.CreateUserError == System.Web.Security.MembershipCreateStatus.DuplicateEmail)
{
    labelDuplicateEmail.Text = "Email address already exists in the database.";
}

}
