Custom scrollbar C#

Question

Hi, can Winforms make such a Scrollbar https://prntscr.com/r65x53?

Answer 1

There are a few paid commercial tools that offer customized look&feel (themes) for Winforms, but I don't think there is a standard easy way to implement this on your own.

Styles are much better implemented with WPF.
