Different type Hierarchy

[Jokerwolf]

Hello,
Here is my gridview.

{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();

            DataContext = from i in Enumerable.Range(0, 10)
                          select new MyObject()
                          {
                              ID = i,
                              Name = String.Format("Name{0}", i)
                          };
        }

        public class MyObject
        {
            public int ID { get; set; }
            public string Name { get; set; }

            public IEnumerable<MyObject2> Items
            {
                get
                {
                    return from i in Enumerable.Range(0, 10)
                           select new MyObject2()
                           {
                               x = i
                           };
                }
            }
        }

        public class MyObject2
        {
            public int x { set; get; }

            public IEnumerable<MyObject2> Items
            {
                get
                {
                    return from i in Enumerable.Range(0, 10)
                           select new MyObject2()
                           {
                               x = i
                           };
                }
            }
        }

        private void SubGrid_DataLoading(object sender, GridViewDataLoadingEventArgs e)
        {
            var grid = (GridViewDataControl)sender;

            var d = new GridViewTableDefinition();
            d.Relation = new PropertyRelation("Items");
            grid.TableDefinition.ChildTableDefinitions.Add(d);

            grid.AutoGenerateColumns = false;
            grid.Columns.Add(new GridViewDataColumn() { DataMemberBinding = new Binding("x") });
        }
    }
}

For the firs time it is child one and then it becomes self-hierarchical. Everything is OK, but in the real programm we use WCF service and MyObject and MyObject2 are DataContracts, and we need to call a WCF service in the get-methods of the Items property.
So, I ask you for help: How could I call the WFC method or maybe there is another way to make such hierarchy.

Hi Jokerwolf,

You should be able to call the WCF service from your WPF application.

ServiceReference1.Service1Client emp = new ServiceReference1.Service1Client();
gridView.ItemsSource = emp.GetEmployees();

You might find this blog post useful.

Do you face any specific problem?

Kind regards,

Sorry, wasn't able to ask a proper question. Everything is OK now.
