Error in CreateUserWizard

I tried this one but I get an error :

hxxp://w w
The code behind is

protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
        Roles.AddUserToRole(CreateUserWizard1.UserName, "Role1");

        TextBox UserNameTextBox = (TextBox)CreateUserWizardStep1.ContentTemplateContainer.FindControl("UserName");
        SqlDataSource DataSource = (SqlDataSource)CreateUserWizardStep1.ContentTemplateContainer.FindControl("InsertExtraInfo");

        MembershipUser User = Membership.GetUser(UserNameTextBox.Text);
        object UserGUID = User.ProviderUserKey;

        DataSource.InsertParameters.Add("ΚΩΔΙΚΟΣ_ΔΙΑΧΕΙΡΗΣΤΗ", UserGUID.ToString());
And the error I get is :

Object reference not set to an instance of an object.

Source Error:

Line 29: object UserGUID = User.ProviderUserKey;
Line 30:
Line 31: DataSource.InsertParameters.Add("ΚΩΔΙΚΟΣ_ΔΙΑΧΕΙΡΗΣ ΤΗ", UserGUID.ToString());
Line 32: DataSource.Insert();
Line 33: }

Any help?
