Hi,

 What's the problem? Do you get any exceptions?

public partial class ReturnType
    {
        [DataMember]
        public IEnumerable<ReturnType> Details
        {
            get
            {
                List<ReturnType> result = new List<ReturnType>();
                if (ShowDetails == true)
                {
                    Service srv = new Service();
                    srv.GetSubReport1(UpdateNumber, KSAID);
                }
                return (result);
            }
        }
    }

Well, I have this code at the service side, and when I get the List of ReturnType objects to attach it to the GridView at the client side, my programm calls the Details too. And when I expand the row, no call for Details, cause they are null already after the previous call. Instead of WPF we can only make async calls. So I can't solve this by just creating the same class at the client side.
