Try this code

this.dataTreeListView1.KeyAspectName = "Id";
this.dataTreeListView1.ParentKeyAspectName = "ParentId";
// to tell DataTreeListView about first row(rows) don't have parent, root rows
this.dataTreeListView1.RootKeyValue = 0;


DataTreeListView shows no results
Previously I was connecting to my Xubuntu machine1 by running on it VNC server first and then using VNC client on machine2 to connect to machine1. The problem is that i had to login anew to my desktop, so I got new X11 session, I believe. 

I would like to connect to my already running X11 session if it's running. Is it possible to do that? If yes, than what should I do?

Thanks in advance.
