Thank you for writing.
The implementation of hierarchy mode depends on your data. When the presented data for Row1, Row2, etc is from the same type, the most suitable hierarchy mode is self-reference
. If the presented data is from different types, you can bind to a hierarchy containing one to many relations
or use load-on-demand
, just like your started to with Rooms, Products, Related products.
If you continue to experience the issue, please send us a demo project with your hierarchy mode setup to investigate it locally and find best solution for your application.
On a side node, please provide me with a link to the problematic video, so I can report it to the respective department.
All the best,
the Telerik team
