ExpandAllItems() causes a rebind, which is very uneffecient. Double time spent on server.
Calling that function every time you need to rebind the control? What a waste...
Is there no way to get this expanded by default without running through the databinding code twice?

Please examine the Load on Demand functionality of the RadTreeList. It allows child nodes to be added on the fly as parent nodes are expanded. This mode is useful when you need to fill sub nodes only when the parent node is expanded or the data source contains thousands of records.
I hope this helps.
All the best,
