I'm working with EntityFramework
and Silverlight, and I'm dealing with this situation. When I try to load the data from a EntitySet
, I have to get the data from a callback.
Now, I need to get the data inmediately, I mean wait until the process finished.
In the next code, the part which I'd like to wait the process is Objectives
property. Or I don't know if I can convert the callback method into a IAsyncResult
, or something like that.
public class EntityService : IEntityService
{
public EntityService()
{
_entities = new DatabaseDomainContext();
}
private DatabaseDomainContext _entities;
public DatabaseDomainContext Entities
{
get { return _entities; }
set { _entities = value; }
}
private EntityList<Objective> _objectives;
public ObservableCollection<Objective> Objectives
{
get
{
if (_objectives == null)
{
var loadOp = _entities.Load(_entities.GetObjectivesQuery()/*, Callback, true*/);
_objectives = new EntityList<Objective>(_entities.Objectives, loadOp.Entities);
}
return _objectives;
}
}
}
