Simple Question on making active only hierarchy selected

[gerrycastellino]

I have several hierarchies coming into a list object displayed as tree view.

I have an expression to display the tree structure, which cannot be changed - I cannot use the PATH for some other technical reasons.

How can I just make the only visible hierarchy in my tree structure view, the hierarchy I have selected in my hierarchy name list box ?

attached is  the ".qvw"  and the hierarchy .qvd.

Any help appreciated !

hey check out this document:

Hierarchies

the ancestor table/ expanded nodes table mentioned here might help resolve your issue with the hierarchy_tree listbox
