Well, another trouble with WinTree binding.

I have an entity Directory. It has properties DirectoryID and ParentDirectoryID. Also it has property SubDirectories, of type List<Directory>, which return all directories that belong to this one on a criteria dir.[ParentDirectoryID]==this.[DirectoryID].

So I have List<Directory> _repositoryDirectories, that I wanna show in a tree in hierarchical view.

From this point  the problems begin to rise.

1. I create columnsetgenerated handler and it fires twice - first immediatly after the binding, second - after I expand any of the first-level directories (root directories). The first one fires with columnset key == "", second - with columnset key == "SubDirectories". Both get processed correctly and I can see the structure of tree with first and second level nodes displayed properly. BUT! When I expand any of the second level directory to get third level - nothing happens. No event is  fired, and I don't see the nodes (but I assured that there ARE directories in the third level). Recursion fails - dunno why. I get two levels only.

2. I checked out your example about recursive binding. It's ok, but it works only upon dataset and datarelation and I utterly hate both of them as being very unsuitable (IMHO) for full-powered ORM.

So I want to ask u to help me to make it work upon object BindingList or any sort of bindable collection - which I tend to use in my applications.

I merely wanna get a recursive binding with all of my nodes showing properly.

THANKS IN ADVANCE!
