实体框架使用.Include绑定到查询

Question

Ok I am trying to do

from s in _db.Students.Include("Advisor") orderby s.LastName select s;

once I get that working there will be several more Includes, but I need to figure this out first. Basically I have no idea how to bind text boxes to the included advisor information. My bindings for the main student data work, but not for the advisor. The bindings look like:

Text="{Binding Path=Advisor.AcadAdv}"

Also the Main grid contains the DataContext to my CollectionView of students objects.

Advisor is a table with an id a foreign key to student and 5 text fields with names of the advisors in them.

Answer 1

According to details you provided, you can:
1) specify item in the binding path (something like this: {Binding Path=Advisor[0].AcadAdv})
2) bind Advisor property to any ItemsControl
3) make a view model, which will have Advisor property as a first item of collection
4) make Advisor a scalar property, not a collection (this will require entity model changes).
