By inheriting from RadDataBoundListBox, RadJumpList gets all the functionality that is normally introduced there. This is also the case with the support for the Check Boxes mode we recently introduced in RadDataBoundListBox. Basically, just as in RadDataBoundListBox, you can enable and activate the check mode in RadJumpList, check/uncheck items and also handle events that inform you when an item has been checked or unchecked. You also have access to the CheckedItems collection which can be used to programmatically check or uncheck items:
