The following example shows how to set the value of this property.

Dim myBorder1 As New Border()
myBorder1.BorderBrush = Brushes.SlateBlue
myBorder1.BorderThickness = New Thickness(5, 10, 15, 20)
myBorder1.Background = Brushes.AliceBlue
myBorder1.Padding = New Thickness(5)
myBorder1.CornerRadius = New CornerRadius(15)
C#
myBorder1 = new Border();
myBorder1.BorderBrush = Brushes.SlateBlue;
myBorder1.BorderThickness = new Thickness(5, 10, 15, 20);
myBorder1.Background = Brushes.AliceBlue;
myBorder1.Padding = new Thickness(5);
myBorder1.CornerRadius = new CornerRadius(15);
