Thank you for writing.
The scroll bar has a specific purpose and is not easy to modify it for scenarios different than to scroll. I have prepared a small project where I have implemented a custom control which follows the design form the image you have attached. As the aim of this project is demonstrational there are some best practices that are not followed e.g there are some hard coded values.
I hope this will be useful. Should you have further questions, I would be glad to help.
