QuestionWhich way to load entity child collections? Pin
UCLAdam16-Jan-13 5:11
memberUCLAdam16-Jan-13 5:11 
Hi

Hopefully this will be a quick question to answer, but personally I'm not sure which way to go.

Firstly I'm using SL5, MVVM, MEF, EF. I have a person entity - the person entity has a collection of account entities, address entities and order entities.

In my view I am displaying a list of the people on the left with the corresponding lists on the right (accounts, addresses, orders). When the person is changed in the list I obviously want the lists on the right to update.

Obviously it would be inefficient to just include the lists in the domain service query using the .Include() operation as it will return ALL the people with ALL the related list entities. This is where my dilemma is - when I change the person do I either:

Load each of these lists separately, each with their own completed events where I populate the view lists. Which is basically three extra calls to the DB.
OR

2. Call a different GetPeople query in the domain service where I pass in the current person ID and use the .Include() operation to include accounts, address and orders, but filter by the passed in PersonID. (i.e. return this.ObjectContext.People.Include("Accounts").Include("Addresses").Include("Orders").Where(p=>p.ID == PersonID);)

Any help is much appreciated.

Thanks.
