How to have a black border around image in c#.the image exists inside a wrap panel

Answer 1

Just add a border to the Image:

<toolkit:WrapPanel x:Name="wp">
    <Border BorderBrush="Black" BorderThickness="5" >
        <Image Source="myimage.png" />
    </Border>
</toolkit:WrapPanel>

Or add it to the WrapPanel in code:

var b = new Border
            {
                BorderBrush = new SolidColorBrush(Colors.Black),
                BorderThickness = new Thickness(5)
            };

var bi = new BitmapImage
                {
                    UriSource = new Uri("/myimage.png", UriKind.Relative)
                };

b.Child = new Image {Source = bi};

wp.Children.Add(b);
