I’ve put together a complex BO and would like to programmatically add some rows to the business object contained within the primary BO when a new row is added to the primary. What would be the best way to accomplish this? There is no RowAdded event so it doesn't appear there is an easy way to determine when a new row is added. One thought was to use the BeforeSave event on the primary BO and loop through its' data table looking at the RowState for each row to see if it was added.

Also what's the ListChanged event for? I can't find it in the Doc.
