Though I do not have a seperate table for heirarchy, I use the same table for heirarchy and accounts. I originally had a similat cCode field which had values like 123234345 but that was what I wanted to remove due to data management tasks.
>The treevie is generatet from this field. Tts extremly fast if you load 20.000 customers in a tree it takes less than 60 sevonds on a local mashine.
Wow that is fast.

I my MS treeview I have borrowed code that does just that it will load upto 2-3 levels only, then when the user clicks on a node + sign that nodes children are loaded.
