See attached screenshot ...
I have a RadDropDownButton with a RadTreeView in it's content. All the nodes in the treeview have a tooltip. When I click on a node the button is set to close (IsOpen=False). The problem is that if a node's tooltip is already displayed it remains on the screen.
you'll be able to find them in code-behind and set their IsOpen property to false.
I've attached a sample project which shows how you ca do this so could you please examine it and if you have further questions feel free to ask.
Kind regards,
