Presumably not much wrong - as far as I know, there's no Tag property
for each item in a ComboBox like e. g. in a TreeView. Such a tag could
be used to overcome this drawback of sorting-and-confusing the list.
In my projects I have been using two approaches to solve the problem:
1) Make a second array with the same contents, unsorted, and search for
the item clicked on in the ComboBox. This will deliver proper results
only when the items are unique. (You don't need to give an index if you
sort it anyway.)
ComboBoxProjects.Add("ZZ")
Background.Add("ZZ")
ComboBoxProjects.Add("AA")
Background.Add("AA")
ComboBoxProjects.Sort()
...when clicked:
PRINT Background.Index(Background.Find(ComboBoxProjects.Current.Text))
(CAUTION: I didn't test this, it's written from memory...)
2) Don't sort the ComboBox list but feed it with a readily sorted and
indexed list from you.
Hope it helps...
