when there are a lot of items checked, the RadDropDownTree displays the names of the checked items and an ellipsis, Unlike the RadComboBox which displays "X items checked" or "All items checked" if the list of checked items is too long. Please add an option for behaving like the combobox UX "[N | All] Items checked". Users do not understand this is a different control and they think it's a combo but unlike the RadComboBox they are getting a different type of behavior when selecting multiple items
