Sending contained object over RIA Services

Question

I have class like this:

public class object {
   [Key]
   int number;

   String mystring;

   OtherObject anotherobject;
}

WHen i sent this over RIA my silverlight application can see object.number and object.mystring, but not object.anotherobject!!! What should i do?? Please help me.

Answer 1

I believe the issue is that you have to make the OtherObject serializable. The other two variables are primitives and therefore they are already serializable.

For Example:

[DataContract]
public abstract class BarrieHibbertWrapper
{
   [DataMember]
   public string Name { get; set; }
}

You will have to add System.RunTime.Serialization as a reference.

It could be that you will have to do the same to the class you included in your code.

Answer 2

You need to use the [Include] attribute on referenced classes to indicate that you want those classes serialized as well:

public class Monkey 
{
   [Key]   
   int number;
   String mystring;

   [Include]
   OtherObject anotherobject;
}

This can also be done in code:

public IQueryable<Monkey> GetMonkeys()
{            
   var Monkey = this.Context.Monkey.Include("Monkey.OtherObject");
   return Monkey;
}

Answer 3

You need to do [Include] and [Association] above the object and the association parameters need to be the other objects [Key]

Also you can send from Server to Client but not CLient to server thats just how RIA works cause it kind of sucks
