Description

Fills a delta dataset with all nested dataset field values.

FetchDetails is used internally to fetch the current values of any nested datasets when the provider is executing its RowRequest method. Source is a source dataset that has the current values for all fields. Delta is a delta dataset that must be updated so that its nested detail fields match the values in Source.
