Sorting List Box when "Show as TreeView" is flaged

[#1]

Hi there,

I have a listbox with "Show as TreeView". When I select a node, there is no sorting. If I unflag the treeview, i.e. a normal listbox, the sorting works Ok.

Has someone faced this problem? Any suggestions?

Thanks in advance.

I understood the explanation.

Unfortunately, the treeview behaviour (even in the example you send) doesn't work as I expected. There is no sorting and, if you flag the Hide Excluded, parents are hidden.

Thanks.
