Answer 1

this is a sample work around that tested with Relaying Command Logic. You will get more detail on WPF Apps With The Model-View-ViewModel Design Pattern .

    
        
    
    
        Maximize
        Minimize
        Restore
    

and in the Windows ViewModel

class Window1ViewModel:ViewModelBase
    {
        public Window1ViewModel()
        {
            CurWindowState = WindowState.Maximized;
        }

        public ICommand CmdMax
        {
            get { return new RelayCommand(param => onCmdMax()); }
        }

        void onCmdMax()
        {
            CurWindowState = WindowState.Maximized;
        }
        public ICommand CmdMin
        {
            get { return new RelayCommand(param => onCmdMin()); }
        }
        void onCmdMin()
        {
            CurWindowState = WindowState.Minimized;
        }
        public ICommand CmdRes
        {
            get { return new RelayCommand(param => onCmdRes()); }
        }

        void onCmdRes()
        {
            CurWindowState = WindowState.Normal;
        }

        private WindowState _curWindowState;
        public WindowState CurWindowState
        {
            get
            {
                return _curWindowState;
            }
            set
            {
                _curWindowState = value;
                base.OnPropertyChanged("CurWindowState");
            }
        }
    }
