C# Form inheritance with new controls

HI guys

I have a main form and created a class that inherits from the main form :

namespace ClientServices
{
class ControllerClass : ClientServices
{
}
}

What happens now is that the ControllerClass looks like the ClientService!

The Problem that I have is that now that I add New controls to the ControllerClass (Via the toolbox) they show but as soon as I compile the application they disappear! Even when you stop the compilation they are gone but the code is still there?

Can anyone please advice?

Thanks

for example :

namespace ClientServices
{
class ControllerClass : ClientServices
{
public void AddButton()
{

Button btn = new Button();
btn.Text = "New Button";
btn.Location = new Point(100, 100);

panel1.Controls.Add(btn);
}

}
}


and then my :

private void TrVHIMenue_AfterSelect(object sender, TreeViewEventArgs e)
{
ControllerClass c = new ControllerClass();
c.AddButton();
}

CAN ANYONE HELP?

Visual inheritance was allways trouble in VisualStudio, so I would prefere composition of user controls over inheritance. But if you really need it, check the z-order of the controls in the designer, and if you want to put the control into a panel from the ancestor, be sure that the modifier of the panel is protected.
