I'll explain, my problem is not set style to control, but how create a style.
I think that the bast way is apply a style to RadRibbonGroup, that contains several RadRibbonTab. These tabs could be into a style.
How can I write this style? Which property I have to define the new style?
RadRibbonGroup has an ItemCollection, how can I do that?
This style could add a list of RadRibbonTab into RadRibbonGroup, and after that, I could add other tabs (by code) also, because tabs of style are common to all views, tabs by code are custom of specific view.
I hope I have clarified the situation.
