    Set the UltraTree.Override.ShowExpansionIndicator property to 'CheckOnExpand', and the expansion indicators will appear regardless of whether the node has children. Handle the BeforeExpand event and populate the node's Nodes collection therein. The 'UltraTree Load On Demand' sample , which is included with the SDK, demonstrates this concept.
