AllowUserChoice not displaying value

I have a dropdown field attached to a dataset and have AllowUserChoice = True. When I entered a value that is not in the ListDatasource it's not displayed after I post the dataset. If I select a value from the ListDataSource it displays fine after a post.
Is there a way to display text from a dataset field in the dropdown even if it's not a value in the ListDataSource?
