FormView.ItemDeleted Event

Occurs when a Delete button within a FormView control is clicked, but after the delete operation.

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

member ItemDeleted : IEvent<FormViewDeletedEventHandler,
    FormViewDeletedEventArgs>

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

A FormViewDeletedEventArgs 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 delete 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 want to access the name/value pairs of the key fields and non-key fields of the deleted record, use the Keys and Values properties, respectively.

For more information about handling events, see Consuming Events.

The following example demonstrates how to use the ItemDeleted event to determine whether an exception occurred during a delete operation.
