Answer 1

You are looking for an owned window. It is always on top of the owner and it gets minimized along with the owner. Good examples of owned windows are the various helper windows inside Visual Studio. You can undock them but they'll always stay on top of the VS main window.

You create an owned window by displaying it with the Show(owner) overload. Or by explicitly assigning its Owner property.

Answer 2

Set the top level and then set the owner, example below.

public Form1()
{
    InitializeComponent();
    Form2 f2 = new Form2();
    //top level not really needed
    f2.TopLevel = true;
    f2.Show(this);
}
