A thickness value; the default is a thickness of 0 on all four sides.

This property only affects a control whose template uses the BorderThickness property as a parameter. On other controls, this property has no impact.

The following example shows how to set the border thickness property of a control.

<Button Name="btn9" BorderThickness="5.0" 
        Click="ChangeBorderThickness" TabIndex="2">
  BorderThickness
</Button>
void ChangeBorderThickness(object sender, RoutedEventArgs e)
{
    if (btn9.BorderThickness.Left == 5.0)
    {
        btn9.BorderThickness = new Thickness(2.0);
        btn9.Content = "Control BorderThickness changes from 5 to 2.";

    }
    else
    {
        btn9.BorderThickness = new Thickness(5.0);
        btn9.Content = "BorderThickness";
    }
}
