void ChangeBorderThickness(object sender, RoutedEventArgs e)
{

    {
        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";
    }
}

Private Sub ChangeBorderThickness(ByVal Sender As Object, ByVal e As RoutedEventArgs)

    If (btn9.BorderThickness.Left = 5.0) Then
        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"
    End If
