I have used the information at http://www.telerik.com/help/wpf/radtimeline-features-grouping.html#ChangingExpandableGroupsCollapsedState to set up the default values for expand/collapse*
I would like to add "Expand All" and "Collapse All" buttons to my page for the user's convenience, however, I can't find a way to do this; is it possible?
*: I have the style set so that all groups start expanded, but oddly, the first time the timeline draws data, the first group is NOT expanded even though the rest are. After this first time, everytime I change the collection bound to ItemsSource, all groups will be expanded
