FormView.ItemUpdated Event


Occurs when an Update button within a FormView control is clicked, but after the update operation.

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

member ItemUpdated : IEvent<FormViewUpdatedEventHandler,

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 key field values for the updated record, use the Keys property. The original and updated non-key field values can be accessed using the OldValues and NewValues properties, respectively.

By default, the FormView control returns to the mode specified by the DefaultMode property after an update operation. To keep the FormView control in edit mode, set the KeepInEditMode property to true.

For more information about handling events, see NIB: Consuming Events.

The following example demonstrates how to use the ItemUpdated event to determine whether an exception occurred during an update operation.
