WPF fullscreen mode

I am creating an WPF application which has following XAML structure.

<Window>
   <ScrollViewer>
       <Grid>
       ...
       ...
       ...
       </Grid>
   </ScrollViewer>
</Window>

I want to run application on fullscreen on the press of 'F' button and for that i tried following code.

private void window1_KeyUp(object sender, KeyEventArgs e)
{

  if(e.Key == Key.F)
  {
       if(!isFullScreen)
       {
            height = mePlayer.Height;
            width = mePlayer.Width;
            mePlayer.Height = System.Windows.SystemParameters.PrimaryScreenHeight;
            mePlayer.Width = System.Windows.SystemParameters.PrimaryScreenWidth;
            this.Background = new SolidColorBrush(Colors.Black);
            this.WindowStyle = WindowStyle.None;
            this.WindowState = WindowState.Maximized;
            isFullScreen = !isFullScreen;
       }
       else
       {
            mePlayer.Height = height;
            mePlayer.Width = width;
            this.Background = new SolidColorBrush(Colors.White);
            this.WindowStyle = WindowStyle.SingleBorderWindow;
            isFullScreen = !isFullScreen;
        }
   }
 }

I am Facing following two problems.

  1. When i press F key for full screen, window goes to full screen mode but task bar is still visible
  2. In full screen mode scroll bar becomes visible.

I don't know why this is happening. I think scroll bar becomes visible because of the taskbar. Any help would greatly appreciated.

Here is the screen shot of what is happening. enter image description here

I'm not sure why you're doing all the extra stuff but doing this seems to be sufficient and working fine:

private void window1_KeyUp(object sender, KeyEventArgs e)
{

  if(e.Key == Key.F)
  {
       if(!isFullScreen)
       {
            this.WindowStyle = WindowStyle.None;
            this.WindowState = WindowState.Maximized;
            this.SC.VerticalScrollBarVisibility = ScrollBarVisibility.Hidden;
            this.SC.HorizontalScrollBarVisibility = ScrollBarVisibility.Hidden;
            isFullScreen = !isFullScreen;
       }
       else
       {
            this.WindowStyle = WindowStyle.SingleBorderWindow;
            this.WindowState = WindowState.Normal;
            this.SC.VerticalScrollBarVisibility = ScrollBarVisibility.Visible;
            this.SC.HorizontalScrollBarVisibility = ScrollBarVisibility.Visible;
            isFullScreen = !isFullScreen;
        }
   }
 }

SC is my ScrollViewer.
