Menu on another form

Hi there.
I ran into some difficulties and I hope someone here can help me.
I created a form (f1) and put a button on it. When the button is pressed I want another form (f2) to pop up with a menu on it. I have been unable to figure out how to put the menu on the f2 form. Here is what I did:

private void button2_Click (object sender, EventArgs ea)

Form f2 = new Form();

Label palli = new Label();

palli.Location = new Point (40, 110);

f2.Controls.Add(palli);

MainMenu MyMenu = new MainMenu();

MenuItem m1 = new MenuItem("File");

MyMenu.MenuItems.Add(m1);

MenuItem subm1 = new MenuItem("Hello");

subm1.Click += new EventHandler(prentavalið);

Menu = MyMenu;
