Remarks

Use the Values property to access the values of the fields for the inserted record. For example, you can use these values to keep a log of inserted records.

The Values property returns an object that implements the IOrderedDictionary interface. The object contains DictionaryEntry objects that represent the fields of the inserted record.

Note

As a shortcut, you can also use the indexer of the IOrderedDictionary object to access the field values directly.
