C＃

   private void TextBox_GotFocus(object sender, RoutedEventArgs e)
   {
      var tb = (TextBox)sender;
      tb.BorderBrush = Brushes.Black;
      tb.BorderThickness = new Thickness(0, 0, 0, 2);
   }

   private void TextBox_LostFocus(object sender, RoutedEventArgs e)
   {
      var tb = (TextBox)sender;
      tb.BorderBrush = Brushes.Gray;
      tb.BorderThickness = new Thickness(0, 0, 0, 1);
   }
