How to Load data on dhmlxtree on aspx page using c#

I need to Tree to load dynamic data from an .Net (Aspx) page that calls data from SQL server.
and that’s where I get stuck and can’t find anything on the web to help me. Do you have an example of someone who has tried this before I can work from? I have no idea how to structure data within an ASPx page.Is there anyway to load the tree without xml. Would really appreciate some guidance.

There is .Net connector for tree:
