Thank you for your vote. Currently, you can get a ListView behavior by using a grouped RadGridView. For additional information, please refer to our online documentation
and Examples application (section GridView >> Grouping).
As to the TreeListView, I admit that it is an interesting feature to develop in a separate control or add as an option in one of our existing control. I am logging your feature request in our issue tracking system, but I cannot provide you with a specific time frame when the desired functionality will be implemented.
I am updating your Telerik points for your feedback.
