QueryableDomainServiceCollectionView not loading query

[Valentin Raceanu]

A few details of my application:

• Silverlight, Ria Services
• I use an application-wide domain context even though I have multiple pages
• I use MVVM design pattern with QueryableDomainServiceCollectionView (QDSCV)

In page1 I have a RadGridView that binds to UsersView:

public class UsersManagementVM : INotifyPropertyChanged
    {
        static UMContext _umCtx = DomainContexts.UserManagementContext;

        class UsersCollectionView : Telerik.Windows.Data.QueryableDomainServiceCollectionView<Users>
        {
            public UsersCollectionView(DomainContext domainContext, EntityQuery<Users> entityQuery)
                :base(domainContext, entityQuery)
            {
                AutoLoad = true;
            }
        };

        public Telerik.Windows.Data.QueryableDomainServiceCollectionView<Users> UsersView
        {
            get
            {
                return vUI.Manager.FromCache<UsersCollectionView>(delegate
                {
                    var y = new UsersCollectionView(_umCtx, _umCtx.GetAllowedUsersQuery(CurrentUser.UserId));
                }
            }
        }
    }

The problem is that when I modify the domain context in another page and go back to page1 then GetAllowedUsersQuery is not called anymore.

Thank you!

Hi Valentin Raceanu,

When you have made changes to the DomainContext, you have to either submit or cancel them before you can load again. The alternative is to use different contexts for viewing and editing purposes.

All the best,
