I've put a bounty on this question because it's a problem I have had regularly since the days of 1.1 and I feel there must be a better solution to this than hacking the table adapter after I instantiate it. However you can use the extended method to wrap the Row Updated event and expose it to other classes (ie My Row Updated) The extension I have a possible alternative.

The code below is to resolve my particular issue with SQL CE to be able to update IDs on the table.

Message) End Try End With End Sub You should set the Update Batch Size property of the Sql Data Adapter to 0 (unlimited).

Update Batch Size = 0 ' You might want to increase the Update Command's Command Timeout as well' adapter. Command Timeout = 600 '10 minutes' Dim table2 As New Data Table("table2") table2. Add(New Data Column("Name", Get Type(String))) table2.

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.

Otherwise, it works fine, and now I have provider-independent event handlers available from the Db Data Adapter class (which is how Microsoft should have implemented them to begin with). ''' Public Delegate Sub Row Updating Event Handler(sender As Object, e As Row Updating Event Args) Public Module Db Data Adapter Extension Sub New() End Sub Private Function Get Event(event Name As String, type As Type) As Event Info Return type.
