Darken the full screen when open popup

Question

I have a window with a button. When you click the button popup appears. How can I darken the full screen when open popup?

You should write your own shader in order to darken, lighten, engraying, moting blurring and doing other cool graphics stuff.

Of course, if you don't want it to do in a right way, you could just create an Rectangle with IsHitTestVisible = false property and black color and some 0.5f opacity all over your form, but...

One easy way to do this is to create a new UserControl like this:

<UserControl ...
<Grid Background="#AA000000"> <!-- control the overlay color here -->
        <Border Background="White" BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Center" VerticalAlignment="Center" Padding="10">
            <TextBlock Text="content"/>
        </Border>
</Grid>
</UserControl>

Than just add it to the top grid of your window.
