Fatemeh,

Being that you have asked other questions about Windows Forms, I am assuming that you are referring to the Windows Forms Ribbon.  You can see what is new in the Windows Forms toolset in the 14.2 Sneak Peek & Product Changes blog post.  There will also be a What's New in Infragistics Ultimate 14.2 webinar next Tuesday that you may be interested in reserving your spot for.

Let me know if you have any questions with this matter.
