How to do Multiple joins in EF, and load datagrid, using VB

I'm trying to load a grid using EF objects.

select * from 
[session] inner join [sessionrep] on [session].ID = [sessionrep].repid
inner join [group] on [group].id = [session].groupid
where [sessionrep].repid = x

I created a partial class and added the properties I wanted to display in the grid in there:

Partial Public Class SessionRep 
Public ReadOnly Property Name() As String 
Get Return Session.Name 
End Get 
End Property 
.... 
End Class

I tried doing th开发者_StackOverflow社区is, but it's only loading the table's Active field, the other fields are blank, although the number of rows appear right.

grdSessions.DataSource = db.SessionReps.Include("Session").Include("Session.Group").Include("Session.Group.Program").Where(Function(r) r.RepID = repID).ToList()

What am I doing wrong ? Thanks.

No need for partial classes.

Dim query = 
From s In db.Sessions 
From d In db.SessionReps 
Where s.ID = d.RepID And d.RepID = repID 
Select s 

grdSessions.DataSource = query.ToList() 
grdSessions.DataBind()
