Data Binding - Unbound Mode

The ASPxTreeList supports unbound mode. In this mode, you need to manually create a tree in code. To create nodes, use the AppendNode(key, parent) method. All you have to do is to specify a unique value, which identifies the node, and a parent node for it, if needed. The AppendNode() method will then create the node and place it at the required position within the ASPxTreeList.
