Hi,
I'm currently using asp:treeview and considering changing to RadTreeView. In order to avoid lots of rework I like to know whether there is an equivalent to the PopulateOnDemand property of the asp:treeview node in the RadTreeView.
When this property is set to True (in code behind whilst manually loading the tree-nodes) the treeview will add the expand image ('+' sign), when clicked, the server side OnTreeNodePopulate event will be called. New nodes can then be added. See also:

Hello,
Telerik RadTreeView supports "Load-On-Demand" feature that allows child nodes to be added on the fly as parent nodes are expanded.
The NodeExpand event fires when the "+" icon is clicked. This event provides the opportunity to add nodes based on the identity of the clicked-on parent node.
For more information about the functionality:
Load On Demand Overview
Server-Side Load On Demand
And the demo: TreeView / Load on Demand Modes
Thanks,
Princy.
