FormViewDeletedEventArgs.Keys Property

Gets an ordered dictionary of key field name/value pairs for the deleted record.

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

member Keys : IOrderedDictionary with get

Property Value

Type: System.Collections.Specialized.IOrderedDictionary
An OrderedDictionary that contains key field name/value pairs for the deleted record.

The Keys property contains the 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 fields (as specified by the DataKeyNames property) for a deleted record. For example, you can use these values to keep a log of deleted records.

NoteNote

This property contains only the key fields specified in the DataKeyNames property. To access the non-key fields, use the Values 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 key fields of the deleted 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 key field values. The advantage in using the indexer is that it returns key field values directly. Data source controls that rely on the field order (such as AccessDataSource) can access key field values only by index.

The following example demonstrates how to use the Keys property to access the values of the key fields for a deleted record.
