Create an item (with Choice/User Fields) using Sharepoint Data Services

Question

I am using Sharepoint 2010 Data Services to create items on a table.

My table has a column called Priority which has High, Medium, and Low items in it.

When I try to create an item in this table via listdata.svc service in c#, Priority field value is not submitted, but the ticket is created on the server. My code is below:

TicketItem obj = new TicketItem();
obj.Title = "test";
IMGCustomerPortalDataContext dataContext = new IMGCustomerPortalDataContext(new Uri("http://server/site/_vti_bin/listdata.svc", UriKind.Absolute));
dataContext.Credentials = System.Net.CredentialCache.DefaultCredentials;
///Tried both of them
//obj.Priority = dataContext.TicketPriority.Where(k => k.Value == "Low").First();
obj.Priority = TicketPriorityValue.CreateTicketPriorityValue("Low");
dataContext.AddToTicket(obj);
dataContext.SaveChanges();

Is there anything I am missing?

Answer 1

after a detailed research I have figured this out.

the link between objects needs to be set explicitly

So, the line below sorted it...

dataContext.SetLink(obj, "Priority", pri);

or

ticket.PriorityValue = "Low";

did the same job...
