The FormView control raises the ItemUpdated event when an Update button (a button with its CommandName property set to "Update") within the control is clicked, but after the FormView control updates the record. This allows you to provide an event-handling method that performs a custom routine, such as checking the results of an update operation, whenever this event occurs.

A FormViewUpdatedEventArgs object is passed to the event-handling method, which allows you to determine the number of records affected and any exceptions that might have occurred. To determine the number of records affected by the update operation, use the AffectedRows property. Use the Exception property to determine whether any exceptions occurred. You can also indicate whether the exception was handled in the event-handling method by setting the ExceptionHandled property. If you need to access the original key field values for the updated record, use the Keys property. The original non-key field values can be accessed by using the OldValues property. Updated values (which include updated key field values, if you allow the user to edit key fields) are accessed using the NewValues property.

By default, the FormView control returns to the mode specified by the DefaultMode property after an update operation. When handling an exception that occurred during the update operation, you can keep the FormView control in edit mode by setting the KeepInEditMode property to true.

For more information about handling events, see Consuming Events.

For a list of initial property values for an instance of the FormViewUpdatedEventArgs class, see the FormViewUpdatedEventArgs constructor.

The following example demonstrates how to use the FormViewUpdatedEventArgs object passed to the event-handling method for the ItemUpdated event to determine whether an exception occurred during an update operation.
