Property Value

The CornerRadius that describes the degree to which corners are rounded. This property has no default value.


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

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);
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)
<Border BorderBrush="SlateBlue" BorderThickness="5,10,15,20" Background="AliceBlue" Padding="5" CornerRadius="15">


Although the property name suggests that you can use only singular values, CornerRadius also supports non-uniform radii. Radius values that are too large are scaled so that they blend smoothly from corner to corner.
