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

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. A FormViewModeEventArgs object is passed to the event-handling method, which allows you to determine the mode to which the FormView control is switching, to determine whether the ModeChanging event was raised as a result of the user canceling an edit operation, or to indicate that an insert operation should be canceled.

To determine the new mode, use the NewMode property. You can also use the NewMode property to switch to an alternate mode by setting it to one of the FormViewMode enumeration values.

Use the CancelingEdit property to determine whether the user canceled an edit operation. To cancel an insert operation, set the Cancel property to true. For more information about how to handle events, see Handling and Raising Events.
