Remarks

Use the Values property to access the values of the fields for the record to insert. For example, you can HTML-encode the values of the record before inserting it in the data source.

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

Note

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