I'm developing a custom control inherited from GroupBox class.

I need to change bounds used by components when they are docking inside the GroupBox (it seems there's an offset value, 13, on the top docking).

Here is a suggestion: Download Reflector from http:// www.aisto.com/roeder. Browse to the GroupBox class, and take a look at the code in the OnPaint method (it automatically decompiles the IL to C#, VB.NET and other languages). I can't see any fixed offset used in there. You can override that method and use the public GroupBoxRenderer class to pass different bounds and experiment.
