WPF Animate Window Visibility Change

Question

I\'m trying to figure out how to animate the change from Visibile to Hidden for a WPF window. The way I currently have the application working is that the window is normally

Answer 1

I did something like that (opacity goes to 0 during 2 seconds and window hides): just look at code, it's simple

MainWindow.xaml:

MainWindow.xaml.cs

    public void ShowMe() {
        (FindResource("showMe") as Storyboard).Begin(this);
    }
    public void HideMe() {
        (FindResource("hideMe") as Storyboard).Begin(this);
    }

Just call HideMe() or ShowMe() instead of setting Visibility = Visibility.Hidden in code

Edit

WPF is slow when moving windows, so if you need sliding animation:

1. Make a transparent window (AllowsTransparency="True" Background="Transparent" WindowStyle="None")

2. Put all your controls onto opaque panel (Background="{StaticResource {x:Static SystemColors.ControlBrushKey}}")

3. Animate this panel's Margin.Left from 0 to window's ActualWidth, then hide a window - this will remove a problem of saving window size
