Listbox Row type

With the Listbox you can add a row as a regular row or as a folder. Is there any function and/or property to check if a row is indeed a folder or a regular row?
I can’t seem to find anyway of doing that (other then using a hidden column where I track all this myself)

Am I overlooking something here or is this a missing feature?


If memory serves, you have to track it yourself. But don’t use hidden columns, use either the RowTag or a CellTag instead.
