You can use Row Updating to modify update behavior before it happens, to provide additional handling when an update will occur, to retain a reference to an updated row, to cancel the current update and schedule it for a batch process to be processed later, and so on.
Row Updated is useful for responding to errors and exceptions that occur during the update.
Get Event(event Name, Binding Flags.[Public] Or Binding Flags. Declared Only) End Function ''' Public Function Add Row Updated Handler(adapter As Db Data Adapter, handler As Row Updated Event Handler) As Boolean Dim upd Event As Event Info = Get Event("Row Updated", adapter.[Get Type]()) If upd Event Is Not Nothing Then Try If handler.

So, with the use of Extension Methods, I added two new methods to the Db Data Adapter abstract class that will allow the adding of event handlers for those two specific events, and here is my implementation (edited 4/23/2013 for handling of instance or static handler methods): I'm using the base Row Updated Event Args & Row Updating Event Args for the event arguments that get returned to the delegate, so if you need provider-specific members that are only available through the provider defined classes that are derived from the above two base event args classes, then they will need to be cast to those classes.
