Load an entity with its navigation properties sorted

Oct 28, 2013 at 11:00 PM
Hi everybody,

I am having a "Patient" entity, which has detail items related to it, like "Diagnosis", "Therapy", "Evaluation", "FollowUp" etc, each having a corresponding DiagnosisList, TherapyList, EvaluationList and so on navigation properties Lists on the root Patient entity.
When I load a specific patient with
var _patient = context.Patient.Where(c => c.ID == this.ID).FirstOrDefault();
I also get all the navigation properties. However, these properties are not sorted in any way.

My question is how do I sort them? Efforts like
_patient.DiagnosisList.OrderBy(n => n.DiagnosisDate);
do not seem to work.

All the best,

This is really an Entity Framework question. The code output is just EF really. That said all LINQ methods will work fine. If you want a list then this shoudl work.

var list = _patient.DiagnosisList.OrderBy(n => n.DiagnosisDate).ToList();

If this does not work, what error are you getting? All "List" objects are just IEnumerable collections. I do not know why your LINQ statements do not work without some sort of error message.
