Or, should I build the treeview manually, creating the root and child nodes and assign the pointer to the node.data property as I create each node? I understand how to create the child nodes of an existing root node, but how do I create the root nodes at runtime?

Hi Sam,
Sorry, but it is not quite correct to use the Node.Data property when working with the data-aware TreeList control. Please try to use an additional field in the data store instead.
However, you can also work with the unbound TreeList control and populate its nodes manually at runtime. In this case, you can use its Add, AddFirst and AddChild methods to populate the control (please review the "TcxCustomTreeListControl.AddNode" topic in the ExpressTreeList help for additional information) and handle the OnDeletion event to deallocate the current node’s data object.
Thanks,
Vito
