oTrans.Notify vs oTrans.NotifyAll

I’m trying to understand what Notify does and whats the difference between Notify and NotifyAll. I have reviewed the customization Guide, it says it notifies bound controls of updates to the underlying data view.

Does it do anything based of that notification? (i.e. refresh control)

I have an issue where if an order is routed to the wrong cell I display a message and un-check orderrel.FirmedRelease on OrderRel_BeforeAdapterMethod. I thought calling notify would refresh the control but it does not.

Any guidance would be helpful
