in the meantime, I have found a workaround, http://forum.nevron.com/shwmessage.aspx?forumid=3&messageid=3489#bm3492 helps me.
First I read my dataset to new DataTable() and this is importable.
Anyway, it would be interesting how to do it directly with dotConnect

thank you

hello,
I evaluate your diagram for ASP.NET, and follow the org-diagram example using NTreeDataSourceImporter. I tried to change datasource to connect to dotConnect for Oracle in direct mode from devart.com but without success. It does nothing ?

Maybe you can provide some basic lines of code to connect NTreeDataSourceImporter.Datasource with a dotConnect source

thank you
