Adding Nodes to a TreeView

[sho_nuff]

Question here:

I have been trying to find a way to add existing nested nodes to a
tree that already has nodes in it:

So, my tree looks like this:

-com
-foo
-goo
-blue
-true

then, i have a node that contains the following children:

-com
-foo
-goo
-blue
-NEW

i try adding this to the treeview's root and then i get two com trees
right next to each other. what algorithm do i need to insert this new
node properly so that the resulting treeview looks like:
-com
-foo
-goo
-blue
-true
-NEW
? Thanks in advance

You need a basic recursion algorithm that does updates of existing nodes and
inserts for nodes that don't already exist. This is called a merge, and
unfortunately
the TreeView doesn't already support a method for it.

yeah, i read that after i posted. anyone have a solid implementation
in C# that does this?
