I have the same issue as reported here. We have a RadComboBox, with an ItemTemplate containing only a RadTreeView. Is there some way to programatically move the keyboard focus to the tree when the drop down area is displayed? It seems like this should be easy to do, but I have not had any success yet.
I've tried hooking the OnClientDropDownOpened event, which allows me to expand the tree and select items, but it does not move the keyboard focus to the treeview automatically. Is there any way to do this so our keyboard-only users do not need to learn another key combination for this?
function RadCombo_OnClientDropDownOpened(sender, eventArgs)
var tree = sender.get_items().getItem(0).findControl("RadTreeView1");
