Thank you for getting back to us.
RibbonBar's "Chunk" and "Group" represents the same visual element. We have completely refactored the layout system of the RadRibbonBar control in Q1 2009
, and we also gave the new name "Group" to this element. However, the term "Chunk" is still used in our documentation because it describes not an actual element class, but the standard element in RibbonBar terminology.
I hope this information is useful. Do not hesitate to contact us if you have other questions.
