• Having a hard time getting this going
  
  Getting a "The underlying provider failed on Open." exception at
  
  return !m_DbContext.Employees.First().Orders.IsLoaded;
  
  I changes connection string in App.config to
  
  Data Source=(local);Initial Catalog=Northwind;Integrated Security=True
  
  Any ideas what I am doing wrong ?
  

• Have you tried to change the connectionstring ? Maybe you need login/password to open your database...
  

• Don't worry - I got it going. I think it was just too late at night. Tried again in the morning and it just all worked.
  
  For reference, this is my AppConfig after modification (this worked fine):
  
  
  
  
  
  
  
  
  THnaks again

• Ok - figured out the DataGrid issue - you have to have the WPF Toolkit installed.
  
  Now the database is not working. I have SQL Express installed - do i need to have the northwind database installed?
  
  Thanks alot for this example - it looks great.
  

• Ok - figured out SQL too - yes, you have to have northwind locally. Also changed the connection string to integrated security.
  
  Thanks again, this is awesome!
  

• Glad to see that you like it :)
  

• it is not working when I use it with Sql Server Compact Edition Northwind Database
  

• This is a great sample! I have looked over many and this one really pares it down to the basics. I think this is going to be the stepping stone I need to move into the more extensive sample apps others have produced. Thanks very much.
  

• HI
  Can you please provide a similar sample where a tree view is used? For example, a Tree view and a label where the label shows the 'Name' property of the selected item in tree view?
  I tried doing something with a ViewModel that contain a ObservableCollection. But the problem is, the CurrentItem is not in sync with the clicked item in tree view.
  
  thank you
