Treeview - Nodes without parent nodes

LJG asked
Last Modified: 2012-05-12
   In the below tree view I only brought in two children of the Root (Red arrows)

   and I >>did not<< bring in:
      Level-1-B  (Green arrow)- but I messed up and brought in all the children  (Blue arrows), grandchildren etc of Level-1-B

The Questions:
1) It appears it doesn't hurt anything if I do bring in the children etc of Level-1-B.  They just don't show.  (I understand it will take longer to load the tree because of my mistake)

2) Is the data anyplace in the tree or does the tree control just ignore the data?
