Erwin, a modeling consultant and top Solver Foundation user, encountered some problems trying to do two-way data binding using DataTable objects.  There are more details on this discussion thread.  Ross, a member of the Solver Foundation team, was kind enough to code up a workaround for Erwin's example.  In addition to this CS file, you will need to create a new DBML file called SampleDataContext, as I described in a previous post.

            context.DataSource = data;
        }
 
 
        // Solve the problem
        public void Solve()
        {
            context.LoadModel(FileFormat.OML, new StringReader(strModel));
 
            Parameter p = context.CurrentModel.Parameters.First(q => q.Name == "p");
            p.SetBinding(data.P, "value", new string[] { "index" });
 
            Decision x = context.CurrentModel.Decisions.First(d => d.Name == "x");
            x.SetBinding(data.X, "value", new string[] { "index" }); 
 
            Solution solution = context.Solve();
            Console.Write("{0}", solution.GetReport());
 
            context.PropagateDecisions();
 
        }
 
    }
