Bob thank you very much for your help and input.

My data will always be sorted as shown in the sample.  I was hoping
that would make things easer.

15 is a parent and a child of itself.  This is a case where, for
example, a business is a part of a group.   Say a purchasing group.
And that same business is the headquarters for the purchasing group.
If the intent is to depict the purchasing group (which is what I have
to do) you end up with
15   Null - root tree node,  purchasing group HQ
15   15 - member of purchasing group
16   15 - member of purchasing group
Etc.

I looked through the information you provided.  I have a handle on
most of it.  But the show stopper is not being able to handel the
child = parent data condition.

Prior to receiving your post I found nthis approach.

Building a dynamic Tree
http://www.codeproject.com/useritems/Dynamic_TreeView.asp?df=100&forumid=462426&
exp=0&select=2242832

I believe it will populate the treeview even with the child = parent
data condition.  Please look at the code and tell me if you think I am
correct.

The problem is it uses the Info column to get the ID and I think it
will only accomidate the one root tree node.  I am thinking it can be
tweeked to work with my data.  But being a novis I am not sure how to
accomplish this.

Your description of the approach you suggested was very clear.  If I
am correct and this will work can you give me some pointers on how to
modify this to work with my data?
