List without repeated elements.

?Is there a way for me to guarantee that a RecordList does not have repeated elements in one of the atributes (the record List is supose to be bound to a Combo Box, and the Record Definition is a Structure)?

If you're listing the values from a query, I would say that you should tune your query, if not, the .NET component SortRecordList ( has a method for that...
Thanks Pedro.
The .NET component is not a valid alternative for me. I will try to use a advance query.
Does anyone know how i can check if an attribute of a entity is in a Record List ?
