An array that contains the names of the key fields for the data source.Use the DataKeyNames property to specify a comma-separated list of field names that represent the primary key of the data source. When the DataKeyNames property is set, the FormView control automatically creates a DataKey object that contains the key/value pairs of the field or fields listed in the DataKeyNames property for the current record. The DataKey object is then stored in the DataKey property.
