I have achieved tree structure using nattable in my application.
For loading each node I need to query database, which takes much time, so my requirement is to load nodes only after expansion event.
What is the best way to implement the behavior in Nattable?
Is it possible to load tree nodes when clicked?

Thank you in advance.

I heard of projects that implemented that. But it is not a trivial task, since you need to have some fake elements in your list to inidicate that there are children, and load them on expand if that element is found.
