Hi,

I am trying to set the background color for the cell at runtime which is not working.

        public ObservableCollection<Customer> Customers = new ObservableCollection<Customer>();
        private XamDataGrid xamDataGrid = new XamDataGrid();

        public MainWindow()
        {
            InitializeComponent();            
        }

        private void OnGetData(object sender, RoutedEventArgs e)
        {
            if (button1.IsEnabled == true)
            {
                Customer customer1 = new Customer { FirstName = "Julie", LastName = "Smith" };

                Customer customer2 = new Customer { FirstName = "Mark", LastName = "Smith" };

                Customers.Add(customer1);
                Customers.Add(customer2);

                this.xamDataGrid = new XamDataGrid
                {
                    FieldLayoutSettings = { AutoGenerateFields = false },
                    FieldSettings = { CellClickAction = CellClickAction.SelectCell },
                    DataSource = Customers,
                    GroupByAreaLocation = GroupByAreaLocation.None
                };

                this.xamDataGrid.FieldLayoutInitialized += this.GridOnFieldLayoutInitialized;
                this.grid1.Children.Clear();
                this.grid1.Children.Add(this.xamDataGrid);

               button1.IsEnabled = false;
            }            
        }

        private void GridOnFieldLayoutInitialized(object sender, Infragistics.Windows.DataPresenter.Events.FieldLayoutInitializedEventArgs e)
        {
            UnboundField unboundField1 = new UnboundField
            {
                Name = "FirstName",
                BindingMode = BindingMode.TwoWay,
                BindingPath = new PropertyPath("FirstName")
            };

            Style style1 = new Style { TargetType = typeof(CellValuePresenter) };
            System.Windows.Data.Binding binding1 = new System.Windows.Data.Binding
            {
                Path = new PropertyPath("FirstName"),
                Converter = new BackGroundConverter()
            };
            Setter setter1 = new Setter(BackgroundProperty, binding1);
            style1.Setters.Add(setter1);
            unboundField1.Settings.CellValuePresenterStyle = style1;
            e.FieldLayout.Fields.Add(unboundField1);

            UnboundField unboundField = new UnboundField
            {
                Name = "LastName",
                BindingMode = BindingMode.TwoWay,
                BindingPath = new PropertyPath("LastName")
            };

            Style style = new Style { TargetType = typeof(CellValuePresenter) };
            Setter setter = new Setter(BackgroundProperty, new SolidColorBrush(Colors.RoyalBlue));
            style.Setters.Add(setter);
            unboundField.Settings.CellValuePresenterStyle = style;
            e.FieldLayout.Fields.Add(unboundField);
        }

I am able to set the background for LastName column but not for the FirstName. Could you please point out what is wrong?
