How to avoid deselecting item when ListBox.Items.Exchange

When using a ListBox I would like to give the user the ability to
rearange the items in the list. This i do with to speedbuttons, one
for moving the item upwards in the list, and one for moving the item
downwards.
What happens is that when I move a item either way,the listbox
deselects that item.
This means that if I want to move a item two steps up, I must first
select the item, press the 'up'-button, select the same item and press
the 'up'-button again.
I'd like to avoid deselecting the item so that the user only has to
select item, and press the button twice.

Is this possible?

Set the ItemIndex property to the item's new index.

If you allow multiselect in the list box, you should use the
"selected" indexed property
