How to delete GroupBox, keeping intact its contencs .NET 3.5, VS 2008 Express

Question

Hello,

A simple, yet annoying one....
I have made a new GroupBox in that contains all my controls (buttons, listboxes, textboxes, etc.).
I wish now to delete the GroupBox which I find impossible.
Whenever I try to delete it, it deletes all its contents.
I have tried to directly delete it by 'delete', I tried by removing its code, I tried shrinking it, but nothing seems to help.
Does anyone know how to get rid of this GroupBox while keeping all its controls?    

Thanks,
Sam
