Rounded Corners in GroupBox Management

Question

How can I get rounded corners in a GroupBox in my form? Is there an option on the properties tab?

Answer 1

If visual styles are enabled for your application and FlatStyleset to System, group fields look as if they have slightly rounded corners, but probably no more than 3-5 degrees. Therefore, I believe that this is not what you are looking for.

Unfortunately, there is no built-in way to adjust its roundness. The only real solution is to use a custom control. You can either inherit an existing control GroupBox, or override its event Paintto draw borders yourself, or you can use one of these existing controls:
