How to close one Usercontrol and open another via Panel

Question

I have userControlVicles inside a Panel, in this Usercontrol has a button to register a new vehicle, I want that when you click the button the panel closes or hide the current Ucontrol and show the new, I managed to show the registration, but I can’t make the old one go away..

private void metroButton1_Click(object sender, EventArgs e)
    {
        UserControlCadastroVehicle userControlCadastroVehicle = new UserControlCadastroVehicle();
        panel1.Controls.Add(userControlCadastroVehicle);
        panel1.Controls.Remove(this);
    }

I thought Remove(this) would close the Usercontrol I was, but it didn’t work, Hide() it goes away, but then add it all up, until the registration I opened.

It looks like this when I click to register

Answer 1

panel1.Controls.Clear();
        UserControlCadastroVehicle userControlCadastroVehicle = new UserControlCadastroVehicle();
        panel1.Controls.Add(userControlCadastroVehicle);

I got it, it was bad for the cloudy kkkk, I started playing with Forms now, but in case someone falls here looking for the answer, okay
