Assembly: System.Web (in System.Web.dll)
Property Value
Type: System.Collections.Specialized::IOrderedDictionary^A System.Collections.Specialized::IOrderedDictionary object containing field name/value pairs that represent the primary key of the row to update.
When the DataKeyNames property of a GridView control is set, use the Keys property (dictionary) to access the value of the primary key in the row to update.

|---|
To access the values of the non-key fields, use the NewValues or OldValues properties. The NewValues property contains the updated values, while the OldValues property contains the original values. |
The Keys dictionary is automatically populated with the name/value pairs of the field or fields specified in the DataKeyNames property. If multiple fields form the primary key, a separate entry is added to the Keys dictionary for each key field.
To determine the name of a key field, use the DictionaryEntry::Key property of a System.Collections::DictionaryEntry object contained in the Keys dictionary. To determine the value of a key field, use the DictionaryEntry::Value property.
