Treeview ?

Is there any way I can save a treeview object into a file, so when I load up the file I can use the saved object to populate a treeview. I have form with a tree view with several nodes and sub nodes and I can't figure out how to save a file where when I load it up it populates the treeview the way it was when you left off.

There are several ways. You could always take that information and bind it to a dataset, thereby allowing you to save the information in something like an XML file - which you could then load the next time your program starts. You could also create a file structure of your own and parse it. Personally, the XML path is better because it would be done in the "recommended" Microsoft way.

I still do not see any functionality in the treeview object itself to save it's current state. I need something to save all the nodes and there subnodes in a ordered manner.

This is where you create your own recursive procedure to do it for you. Here's the pseudo-code for what I'd do:

MyFunction(ByVal Node)
For Each node in TreeView
If node Has children
'Get the next level
'This is the bottom of the tree
End If
End Function
