FormViewUpdatedEventArgs::Keys Property

Gets a dictionary that contains the original key field name/value pairs for the updated record.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public:
property IOrderedDictionary^ Keys {
	IOrderedDictionary^ get ();
}

Property Value

Type: System.Collections.Specialized::IOrderedDictionary
An IOrderedDictionary that contains a dictionary of the original key field name/value pairs for the updated record.

The Keys property contains the original values of the key fields listed in the DataKeyNames property of a FormView control. Use the Keys property to access the values of the key field for an updated record. For example, you can use these values to keep a log of updated records.

NoteNote

If you allow the user to update the values of the key fields, the Keys property contains the original key field values. The updated values are stored in the NewValues property.

The Keys property returns an OrderedDictionary object that implements the System.Collections.Specialized::IOrderedDictionary interface. The OrderedDictionary object contains System.Collections::DictionaryEntry objects that represent the fields of the updated record. To access the field names, use the Keys property of the OrderedDictionary object. Similarly, you can access the field values by using the Values property.

NoteNote

As a shortcut, you can also use the indexer of the OrderedDictionary object to access the field values directly. Data source controls that rely on the field order (such as AccessDataSource) can access field values only by index.

The following example demonstrates how to use the Keys property to access the values of the key field for an updated record.
