Entity Framework question Part 2, asp.net

As shown below, some customers have each zero or many orders. To do this, I added a template field (Orders) and inserted a gridview in it with Bindings Eval("tblOrders"). I also entered  tblOrders to Include property of EntityDataSource1 .EF_5
But in the case of Items template field, after setting  Bindings Eval("tblOrderDetails"), I do not know where and how to add tblOrderDetails so the Include property?

I am trying to display Order Details (Items) or each order. The project solution (EF_YouTube.zip about 1.1 MB with db file in it is at:  https://onedrive.live.com/?cid=420CDD6A13807C9B&id=420CDD6A13807C9B%21116 for additional information. It is developed in vs2012 and uses SQLEXPRESS12)

Question: How can I make this application to show Order_Details (Items) as well?EF6

Hi eghtebas;

I am not an ASP.Net developer and so I did not know how to modify this property using the smart tabin the designer so I modifyed it directly in tthe HTML.

The Include attribute needs to be modified to include all the tables you wish included. All path to a table must start from the main source which in this case is tblCustomers. So to include order details using a comma separated list of paths in the Include string you add tblOrders.tblOrderDetails as shown below.

<asp:EntityDataSource ID="EntityDataSource1" 
                      runat="server" 
                      ConnectionString="name=OrderModel" 
                      DefaultContainerName="OrderModel" 
                      EnableFlattening="False" 
                      EntitySetName="tblCustomers" 
                      Include="tblOrders, tblOrders.tblOrderDetails">
</asp:EntityDataSource>
