I am trying to add new column to xamdatagrid on fly. I am getting the column anseright but I can't fill it. 

Can someone show me what I am doing wrong.

Here is xml

  <igDP:XamDataGrid  DataSource="{Binding Path=Container.Columns}" GroupByAreaLocation="None" 
                            FieldLayoutInitialized="xamDataGrid_FieldLayoutInitialized"
                         >

            <igDP:XamDataGrid.FieldLayoutSettings>
                <igDP:FieldLayoutSettings AutoGenerateFields="False"
                                        AutoFitMode="Always" 
                                        AllowAddNew="False"

                                          
                                          />

            </igDP:XamDataGrid.FieldLayoutSettings>
            </igDP:XamDataGrid>

C# code

 public partial class SpreadsheetView : Window
    {
        public SpreadsheetView()
        {
            InitializeComponent();
        }

        public SpreadsheetViewModel ViewModel
        {
            get { return this.DataContext as SpreadsheetViewModel; }
        }

        void xamDataGrid_FieldLayoutInitialized(object sender, Infragistics.Windows.DataPresenter.Events.FieldLayoutInitializedEventArgs e)
        {
            List<ISimulatedValue> container = this.ViewModel.Container.Columns;

            

            for (int i = 0; i < container.Count; i++)
            {
                var field = new UnboundField
                {
                    Name = container[i].Name,
                    BindingMode = BindingMode.TwoWay,
                    BindingPath = new PropertyPath(String.Format("{0}[{1}]", nameof(ISimulatedValue.AllValues), i)),
                    AllowEdit = false,
                    Format = "P2"


                };

                field.Settings.EditAsType = typeof(String);
                e.FieldLayout.Fields.Add(field);


            }



        }


    }

I got the colum names right, but I can't fill them.

ISimulatedValues.AllValues returns double array
