How can I change the border thickness of a Groupbox on a windows form in C#?

c#, groupbox, winforms

Solution

You'll need to make a custom `GroupBox` control. See The Grouper - A Custom Groupbox Control

Problem

I didn't find any solution that helped me on the older questions on SO... Is it possible to make them thicker or just more visible by changing the color? If yes, some code would be great... or just a hint how to do it...
