Sort data in dropdown

I have a dialog with a drop down. The dropdown contains a list of sales managers. I need to make sure that they appear in alphabetical order ( they are not currently in alphabetical order ). How do i do this?

Do you mean in a lookup in AX client? You can override the lookup method and add a sort field to the query.
If it’s a report dialog (as your other forum suggests), you want to register the override method in the UI builder class.
