RIA Services and Relationships in Silverlight 3

Question

I've finally managed to get a handle on loading information using Silverlight, ADO.NET Entities, and RIA Services, but I'm still having a problem with getting the information about the relationships.

For instance, imagine a product, and that product has several categories of attributes. We'll call them ProductAreas.

The Product object has a property called ProductAreas (as a result of their relationship), but when I call:

ctx.Load(GetProductsQuery());

(Where ctx is my DomainContext), the Product objects returned have the ProductAreas property, but it contains no elements, which is a very serious problem, in my case.

So the question is: How do I get access to these relationships?

Answer 1

I'm not sure what your GetProductsQuery() method does, but you should be able use the .Include('ProductAreas') method in your query. If you update your question with the contents of that method I'll try to help more.
