Try olv.Objects = null;

Clear() comes from ListView and is the nuclear option!

One question more... it is possible sort after start olv another column than
first...

Clear() doesn't work for me, but this does:

olv.ClearObjects();
olv.Items.Clear();
olv.Columns.Clear();

But, that is when I'm using Generator.GenerateColumns().

I have a lot of trouble using ClearObjects() with a TreeListView and spent a
lot of time debugging the issue ( I though ) from my part of code. Finally I
digged into the source and found out that this method simply call SetObjects
with an empty List. It should work. However, there're also the
mapObjectToBranch and the mapObjectToIndex dictionaries to reset otherwise you
will have funny results trying to update data to a TreeListView. For testing I
reset those two dictionaries when the SetObjects is called and it works
nicely. I don't know if this is a bug or it was intended that way.
