Description
Positions a dataset on the record that corresponds to the current update in a specified delta packet.
LocateRecord is called indirectly by the RowRequest method to locate a record before fetching information about it. The Source parameter is the dataset containing current record values. The Delta parameter is a delta packet that identifies the desired type of information and information identifying the desired record.
LocateRecord uses the criteria specified by UpdateMode to identify the desired record.
