Hello again rebtech,

It dawned on me that you probably want to expand and collapse the RibbonBar (as you normally would be double clicking on a tab). If this is the case, please take a look at this forum post

Hope that helps

Hi rebtech,

Thank you for the writing.

In case you want to collapse or expand a RadRibbonBar group, you should collapse the approach demonstrated below. If you want to collapse the whole RadRibbonBar, you should follow the suggestion provided by Richard.

The collapse operation in RibbonBar is performed in the public class ExpandableStackLayout and each item in this StackLayout that descends from the public abstract class CollapsibleElement can be expanded or collapsed. By default, ExpandableStackLayout checks if the sum of all sizes of the elements is bigger than the available space and calls the CollapseToStep method for these elements with CollapseStep smaller thanCollapseMaxSteps.

The values of CollapseToStep are:

Copy Code

public enum ChunkVisibilityState : int
{
Expanded = 1,
SmallImages = 3,
NoText = 2,
Collapsed = 4
}

You can easily collapse any collapsible element with the CollapseElementToStep method and expand it with the ExpandElementToStep method. 
Please refer to the attached project for more details.
