FormViewDeletedEventArgs.Values Property


Gets a dictionary of the non-key field name/value pairs for the deleted record.

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

Public ReadOnly Property Values As IOrderedDictionary

Property Value

Type: System.Collections.Specialized.IOrderedDictionary

An OrderedDictionary that contains a dictionary of the non-key field name/value pairs for the deleted record.

Use the Values property to access the values of the non-key fields for a deleted record. For example, you can use these values to keep a log of deleted records.


The Values property is populated only when two-way binding expressions are used in the item template. For more information on two-way binding expressions, see Binding to Databases.

The Values property returns an OrderedDictionary object that implements the System.Collections.Specialized.IOrderedDictionary interface. The OrderedDictionary object contains System.Collections.DictionaryEntry objects that represent the non-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.


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

This property does not contain the key fields (as specified by the DataKeyNames property) for the deleted record. To access the key fields, use the Keys property.

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