I have a _ reservation_ entity which has a field _ accountId_
How can I handle an event for _ accountId_ changed in both the GUI and in the entity class?
BL
If your BL class extends the reservationEntity class, then you can handle the accountId changed event by overriding OnAccountId in the BL's reservation class. Example, extended templates and JCL in 3rd party downloads
if you are using the manager class architecture, then when you declare your object variable for the accountId entity, add code to handle its AccountId changed event:
AddHandler m_reservation.AccountIdChanged, addressof handleAccountIdChanged
But remeber to do the reverse (RemveHandler) when you have no more use for the m_reservation variable.
UI
In your UI you would use an approach similar to that in the BL-Manager class architecture. Your reservation variable can be declared with Events or you could use AddHandler/RemoveHandler to assign a routine to handle the accountIdChanged event.
