You normally would not do this. Instead of using a Form, you would make your "form" as a UserControl and show the control in the panel instead.

The problem with showing the Form "as a control" in a Panel is that the user will still be able to manipulate the form, move it around in the Panel, minimize it, maximize it, even close it!, just like the same form on the Desktop.

But, to answer your question, you have to call a Win32 function, SetParent, with the WindowHandle of your Form and the WindowHandle of your Panel control to make the Panel the new parent of the Form. Examples:

The answer is really simple....

public void nav(Form form, Panel panel)
        {
            form.TopLevel = false;
            form.FormBorderStyle = FormBorderStyle.None;
            form.Parent = panel;
            form.Dock = DockStyle.Fill;
            form.Show();
        }

....and to remove it, just set the form's parent to null - if you want to show it by itself, you'll have to reset the borderstyle/toplevel/etc. this code assumes it'll always be in a container.

public void navclose(Form form)
        {
            form.Parent = null;
        }
