is it possible to set 100% height on the panelbar for MultipleExpandedItems. I want a UI style in which i have a panelbar occupying 100% height with multipleexpandeditems mode. There can be 2-3 panelitems inside that and inside each panelitem there would be a treeview control which should also occupy 100% height of that panelitem. In such a way that scrollbars of treeview are visible and not of the panelitem. I tried but somehow 100% was not working. Is this a known limitation or any workarounds exists?
