How to bound a WPF window into desktop

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 .

 x:Class="WpfMvvmTestCSharp.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:vm="clr-namespace:WpfMvvmTestCSharp"
    Title="Window1" Height="300" Width="300" WindowState="{Binding CurWindowState, Mode=TwoWay}">
    
        
    
    
         Command="{Binding CmdMax}" Height="23" Margin="12,25,0,0" Name="button1" VerticalAlignment="Top" HorizontalAlignment="Left" Width="75">Maximize
         Command="{Binding CmdMin}" Height="23" Margin="101,25,102,0" Name="button2" VerticalAlignment="Top">Minimize
         Command="{Binding CmdRes}" Height="23" HorizontalAlignment="Right" Margin="0,25,13,0" Name="button3" VerticalAlignment="Top" Width="75">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;
        }
