Don't show sorting indicator

I’m doing a fake hierarchical listbox. Because there is a normal listbox next to my fake hierarchical one I want to keep the header. Sorting makes no sense, though.
With

Function HeaderPressed(column as Integer) Handles HeaderPressed as Boolean 'don't sort Return True End Function

I avoid that the listbox can be sorted. However, I still see the sorting indicator. How do I get rid of that?

What is your ListBox.ColumnSortTypeAt ?

LB.SortedColumn = -1 LB.HasHeading = False LB.HasHeading = True

Of course, LB is the name of my Listbox. Worked in API 1.

Thanks, that’s what I was missing.
