GridViewUpdatedEventArgs Class
Assembly: System.Web (in system.web.dll)
The GridView control raises the RowUpdated event when an Update button (a button with its CommandName property set to "Update") within the control is clicked, but after the GridView 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 GridViewUpdatedEventArgs 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 GridView control returns to read-only mode after an update operation. When handling an exception that occurred during the update operation, you can keep the GridView control in edit mode by setting the KeepInEditMode property to true.
