I am using WinForms Q2 2010 SP2 RadRibbonBar control.  According to http://www.telerik.com/help/winforms/ribbonbar-end-user-capabilities-collapsing-the-ribbonbar.html, the right-most RadRibbonBarGroup will collapse to a simple rectangle when the form containing the RadRibbonBar is resized smaller than the RadRibbonBarGroup size.  This isn't working for me.  When I resize the form to a smaller size, ALL of the RadRibbonBarGroups collapse AND none of them collapse to a simple rectangle.  How do I manage this programatically?

Just to expand a bit. The section of the project I am working on is allowing the user to create an ad-hoc query where each RadRibbonBarGroup hosts a user control to help the user select a specific element of the query.  What I actually need to do, after I can get control over ALL of the RadRibbonBarGroups collapsing when the form is smaller than their total widths combined, is to gain programatic control over collapsing and expanding any selected RadRibbonBarGroup.

The RadRibbonBarGroup.Visibility property doesn't do this for me.

1. But which property do I set to collapse the RadRibbonBarGroup to a simple rectangle that contains the down-arrow icon (that dispays the hosted control when clicked)?
2. What property do I set to change the image from a down-arrow icon to one of my choosing?

That worked.  Thank you very much.

Your product is great!
