Hooking into DataSet Auto Generated Code

I have an application that I am trying to use auto generated code as much as
possible. It makes writing the application so much easier.

I have created a DataSet based on an SQL database connection. VS2008
generated the dataset class and code.

I need to insert some logic in the UpdateAll method just before the
workConnection.Commit() statement. I will be using the allAddedRows and
allChangedRows item arrays.

I know that if I make changes here they will be erased if the code is
re-generated.

Is there a method I can override or an event I can subscribe to that will
let me do something with the database just after the additions and changes
are made? I can start my own transaction if I need to, but I need access to
the arrays of added, changed and deleted records.

Again, I want to keep things as auto generated as possible.
