Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
This property contains only the key fields. To access the values of the non-key fields, use the Values property.
The dictionary is automatically populated with the name/value pairs of the field or fields that are specified in the DataKeyNames property. If the primary key contains multiple fields, a separate entry is added to the dictionary for each key field.
To determine the name of a key field, use the DictionaryEntry.Key property of a DictionaryEntry object that is contained in the dictionary. To determine the value of a key field, use the DictionaryEntry.Value property.
