Hello Everybody

I have a treeview structure with about 2000 nodes over n levels.
Normaly only the root is expanded.
Now the user wants to see the full path from a special child node backwards to root(= autoexpand all nodes that point to the special child).
(expanding the parent node of the child + the parent node of the parent node + ... = fullpath backwards)
Example:
root
n1,n2,n3
...,n2.1,n2.2,n2.3,...
...,n2.2a,n2.2b,n2.2d,....
...,n2.2b1,n2.2b2,...

So if the given child key is n2.2b2 i want to expand root,n2,n2.2,n2.2b and point to n2.2b2
The keys of the nodes have no structured id's as in my example. (just idnnnnnn)
In VB there is a function "fullpath" to handel this.
How to code this behavior in foxpro.(VFP 9.2)

Any help welcomed.
Best regards
Albert
