Hi,
Thanks for your feedback.
I am not sure what is your real concern. Why you can not use GDI to draw
the line?
Yes, I think your workaround of using picturebox border should work.
However, because control embeded extra code in it, which may cost some
performance. So I think using GDI to draw the line should be more
effective. Thanks
Best regards,
