Hi Enmanuel, I played around with your code and got the same results as you did ( controls not appearing in derived classes ) what you need to do is this, after adding some controls using the designer ( I used buttons ) you need to put this code in the constructor and you will find your derived classes have your controls, let me know how you get on
public WinFormaBase()
{
this.InitializeComponent();
}
