Popups do - as far as i know - not suppot such a behavior, their intended usage is for ComboxBox-dropdowns and the like as far as i can tell. To realize something like that you can use a normal Window and set its Owner to the main window on which it should be dependent. This will cause the popup-window to stay on top of its owner & to minimize together with the owner.

e.g.

public class ChildWindow: Window
{
    public ChildWindow(Window owner)
    {
        this.Owner = owner;
    }
}

var popup = new ChildWindow(mainWindow);
popup.Show();

(Windows cannot be re-opened once closed, so to reuse a window you just have to Hide() it when the user tries to close it (handle Closing event and cancel using event args))
