    Let me make a quick clarification. The LoadOnDemand feature is designed to load dynamically the items of the RadTreeView control. Once the items are loaded, there is no need to load the them again, when you expand a node for second time. In other words this feature is designed to increase the performance of the control by loading fewer items for the first time and load only the desired items (not all the data). For more information you can refer to this article.
