For example, when a new item is added to a list, we may need to perform some action like say, notifying the person who created the list item, or modifying the dependent entries in some other location etc.Handling of such events is facilitated by event receivers.This allows you to provide an event-handling method that performs a custom routine, such as HTML encoding the values of a record before updating it in the data source, whenever this event occurs.A Form View Update Event Args object is passed to the event-handling method, which allows you to determine the value of an optional command argument sent to the Form View control and to indicate that the update operation should be canceled.event is raised when an Update button within a Details View control is clicked, but before the update operation.This allows you to provide an event handler that performs a custom routine, such as canceling the update operation, whenever this event occurs.
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.
The command argument value corresponds to the Command Argument property of the Update button.

A List View Updated Event Args object is passed to the event handler, which enables you to determine the number of rows affected.
It also lets you determine what exceptions might have occurred.
