I Have a couple CommandBarComboBox in a toolbar plug-in for ProcessBook which have assigned tooltips. But when you hover over the text inside the CommandBarComboBox the tooltips shows “Unassigned”. I am assuming that the items tooltips how do I set this tooltips? I noticed that I can not access the items and the additem does not have a tooltips parameter. I would be happy even if I could assign nothing for this. I just don’t want the “Unassigned” to show.
