I'm not sure if this is the best place for this question or in the BusinessObjects section...



I have several hierarchal data structures and would like to present them in a tree view. Some of these structures are from within a single table and some span multiple tables. I looking for any suggestions, guidelines on the best way to do this. I'm assuming that in any case I'm likely going to be getting a DataTable from a BO and manually building the tree, but maybe there is a better way.



So, the two types of hierarchies are:



1. parent child within a single table

2. parent child within a single table and with children within another table



So, how best to implement this sort of thing?
