When my application starts data is loaded into a treeview. The user then typically expands parts of the treeview, and then reloads the data to see if something new has appeared. I would like the expanded nodes to stay expanded after the reload.
I've tried to use radtreeview. SaveXML(filename) and radtreeview.LoadXML(filename), and it works fine. But I don't want to read and write from a file, so I would like to use radtreeview.Save/LoadXML(stream) instead, but I can't figure out how to do it.
It would be great if someone could share code which helps me accomplish this.
Thank you very much!
