item position on a tree

does any one have experience with this?

I have a database source that givesthe items to load in a treeview and their position relative to one another...

so i have id,title,relID, rel

in VB this are default paramaters of the treeview object but I'm using .net and an infragistics treeview control...

well I made four positions, Firstchild, NextSibling, previousSibling and LastChild

And i don't know what's the next thing to do...

First how will I load it to the tree and next is if made a new item the lastchild so my previous last child position should change right? same with previous sibling...errr...

i would really appreciate any help


Thanks
