Custom Collection Binding

[barski]

I've been tinkering with the whole n tier "business layer" concept for a few months now. I found two articles that I really liked so I've tried to combine the two. The reason for not using one or the other is that I really prefer to let the dataset/dataadapter object communicate with the database for updates, inserts, deletes but want a collection to deal with validation type things etc....

Now my problem as i see it, I'm sure others could find other problems, is when to use remove or delete for the datarow. I'm attaching an example.

 

Basically, I'm trying to merge two good ideas from other people
