Hello All,

Ok, I have read a bunch of post and understand that lazy loading and adapter do not fit well in the current design.

However, I would like some insider views for a very common problem (IMHO) and the way, you guys resolved it using adapter:

I am having a DAL, and a BL (Manager classes).

Then on the PL side, I have a complex form with customer’s information.

On this form I have a lot of tab pages for, for example, customer’s orders, customer’s subscription, customer’s interests. Each of the tab contains a collection (0-n relations): - Customer.Orders - Customer.Subscriptions - Customer.Interests

How would you handle that? I only want to load the data when the user clicks on a tab and not load everything into memory at the displaying of the form. Code snipplet for BL, DAL and PL appreciated

Cheers,

Silat

There must be an event raised when switching between tabs, and then you should use the example shown in the docs "Using the generated code -> Adapter -> Using the entity collection classes -> using a related entity" to fetch the related entities.

Example:

// C#, .NET 1.x
CustomerEntity customer = new CustomerEntity("CHOPS");
DataAccessAdapter adapter = new DataAccessAdapter();
EntityCollection orders = customer.Orders;
adapter.FetchEntityCollection(orders, customer.GetRelationInfoOrders());
