dealers.png

I am using EF4 and a WCF RIA DomainService. One of my entities represents a "Dealer." There is then a table in the DB called DealerContact, which is represented in my model as an entity of the same name. It has a related table called Contact. Thus allowing us to list multiple contqacts for a single dealer.

Dealer (Class has a DealerCntacts EntityCollection attribute)
* DealerContacts (each DealerContact has a single Contact attribute)
* Contact

I have an SL page with Two RadGridViews. The first displays all dealers. The second RadGridView displays the DealerContacts collection of the selected Dealer. I then wired up a DataForm control to the first RGV displaying the dealer and it works flawlessly. What I want to do now is allow a new Contact to be created using a RadDataForm. I cannot seem to get that to work properly. I have attached an image of the UI for better clarity.

When I attempt to insert the new Contact it shows up as all fields blank in the RGV regardless of what I type in the DataForm and the new item is not saved. I receive no errors.

Thanks!

Hello Robert,

Some XAML and/or code behind would be helpful for me to see what went wrong. Meanwhile I may give a suggestion - You may handle Edit Ended event of the RadDataForm and inside call the update method of your context.

Since this is a common question , I am also going to prepare a small online sample application with RadGridView , RadDataForm and full crud support with RIA services. I am leaving the thread open , so I can later notify you when the sample is ready .

schema-dealer-contact.png

Ivan, thanks for the reply but your example is too basic to really help me. As I stated in my initial message the issue is not simple CRUD on the top level object. That is very easy to do and understand with the DataForm (which I have fallen in love w/ BTW - you guys rock!). What I am trying to do is insert at the 3rd level of the main object in the DomainDataSource. So again, I have a DomainDataSource that contains the dealer objects. The Dealer entities have a navigation property called DealerContacts (a bridge table in the database), each of which has a navigation property called Contact. I have included an ERD of the three tables. I can CRUD all day long on the Dealer entities. I can update the Contacts on this page as well, but I don't understand how to Create a new contact in this exact situation where the DomainDataSource has the dealer at the top level.

Basically I have said I need to know how to get from point A to point C. I know how to get to point A. I don't know how to get to point C from point A. And you have handed me a map on how to get to point A.

SilverlightApplication6.zip

Hello Robert,

First of all, excuse me for the late answer. Since your question is more related to entity framework and RIA services in general than to the functionality of our controls, I fear that I cannot give you a complete solution to your business problem. Nevertheless I created an example for you, utilizing tables from Northwind that are in the same relation as yours. Please, refer to it and inform us if this setting is close to your requirements.

All the best,

Hello Ivan,

Thank you so much for the example named SilverlightApplication6. It's been very helpful!

In the code-generated file, SilverlightApplication6.Web.g.cs, the following methods are being generated. I'm trying to develop a similar project, but the EntityQuery<> methods aren't being generated. In your example, in the MainPage.xaml.cs, you use one of these queries (GetRelatedProductsQuery). Do you know what's required to get these methods generated?

public EntityQuery<Order_Detail> GetOrder_DetailsQuery()

{

this.ValidateMethod("GetOrder_DetailsQuery", null);

return base.CreateQuery<Order_Detail>("GetOrder_Details", null, false, true);

}

public EntityQuery<Order> GetOrdersQuery()

{

this.ValidateMethod("GetOrdersQuery", null);

return base.CreateQuery<Order>("GetOrders", null, false, true);

}

public EntityQuery<Product> GetProductsQuery()

{

this.ValidateMethod("GetProductsQuery", null);

return base.CreateQuery<Product>("GetProducts", null, false, true);

}

public EntityQuery<Product> GetRelatedProductsQuery(int pK)

{

Dictionary<string, object> parameters = new Dictionary<string, object>();

parameters.Add("pK", pK);

this.ValidateMethod("GetRelatedProductsQuery", parameters);

return base.CreateQuery<Product>("GetRelatedProducts", parameters, false, true);

}
