Textfield : Password

I know I can do the following to create a password field,

    Dim pw As TextField = New TextField(FieldType.Password)
    pw.Move(20, 80, 320, 28)
    pw.Placeholder = "Enter your password"
    w.AddSubview(pw)

how do I do the password with FieldType.Password when using Control block??

    Control TextField x_Password
        Frame = (20, 80, 360, 24)
        Placeholder = "Enter your password"
    end Control
