Remarks

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

Note:

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

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

Note:

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