I’m having some trouble compiling this in VS2010 with the BlendSLSDK_en.msi installed to get the Interactivity dll. I’m getting the following error:

Error 1 Unknown build error, ‘Cannot resolve dependency to assembly ‘System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e’ because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.’ FullScreenDemo

I would like more interactivity on full-screen mode such as: (1) key toggle between than only press ESC backing to normal state. (2) when i restore the window to normal mode, it should keep pre-state before it is made full-screen.

So, i added your code.

(1) Support to toggle modes - creates a new attached property that names FullScreenKey, Key type, its default value is F11 (like common WebBrowers) - in Window_KeyDown method involves the keyDown event, add a if statement

     private void Window_KeyDown(object sender, KeyEventArgs e)
    {
        var fullKey = GetFullScreenKey(AssociatedObject);
        var isFullScreen = GetIsFullScreen(AssociatedObject);

        if (e.Key == fullKey && e.Handled == false)
        {
            SetIsFullScreen(AssociatedObject, !isFullScreen);
        }

        else if (e.Key == Key.Escape && e.Handled == false)
        {

            if (RestoreOnEscape)
            {

                SetIsFullScreen(AssociatedObject, false);

            }   // if

        }   // if
    }

(2) Keep pre-state of the window - In OnIsFullScreenChanged handler method, changes little … if (newValue) { // stores its pre-fullscreen state window.Tag = window.WindowState;

                window.WindowStyle = WindowStyle.None;
                window.Topmost = true;
                window.WindowState = WindowState.Maximized;

            }   // if
            else
            {
                window.Topmost = false;
                window.WindowStyle = WindowStyle.SingleBorderWindow;

                // set back to pre-state
                //window.WindowState = WindowState.Normal;
                window.WindowState = (WindowState)window.Tag;
            }   // else

….

quite great, happy coding!

Nice behavior and tip !

As I am pointing out in my blog’s post (http://blog.lexique-du-net.com/index.php?post/2010/09/23/Quick-tip-%3A-My-WPF-Fullscreen-window-still-display-a-border-on-right-and-bottom-side…-how-to-remove-it) without putting the ResizeMode to NoResize, some borders may still be visible …

Have a nice day :-)

Creating a fullscreen window in WPF is quite simple, you just have to set WindowState to Maximized and WindowStyle to None. But in my current project I was facing a little drawback : a border was still visible on the bottom and on the right side of my…
