I've successfully bound data to the grid; however, when the model bound to the grid changes the results don't show up in the grid until I give focus to that row.  For the purposes of this issue, don't worry about the meaning of the "scans" and "_snc" objects as they have nothing to do with the issue.

Here is where I successfully bind to a model called "ComparisonScansViewModel" which has a public "List<ComparisonScanViewModel> Scans" property.

            await Task.Factory.StartNew(() =>
            {
                // source scans for comparison
                _model = new ComparisonScansViewModel(_snc, scans);
            });
            BatchComparisonGrid.DataSource = _model.Scans;

Here is the model code (loads up fine)

    public class ComparisonScansViewModel
    {
        public ComparisonScansViewModel(SNC snc, List<Scan> scans)
        {
            Scans = new List<ComparisonScanViewModel>();
            scans.ForEach(s =>
            {
                Scans.Add(new ComparisonScanViewModel()
                {
                    Id = s.ScanId,
                    Type = snc.Values.GetInstance(s.Type).Text,
                    Field = s.FieldSize.ToString(),
                    Energy = s.EnergyForDisplay,
                    Depth = s.Depth,
                });
            });
        }
        public List<ComparisonScanViewModel> Scans;
    }
    public class ComparisonScanViewModel
    {
        public int Id { get; set; }
        public string Type { get; set; }
        public string Field { get; set; }
        public string Energy { get; set; }
        public decimal? Depth { get; set; }
        public decimal Gamma { get; set; }
    }

In the code below I am hard coding the value of a property in my model named "Gamma".  When the grid is first shown this value is '0' and when the value changes in a dropdownlist I am going to properly update the "Gamma" value; however, for the purposes of debugging I am simply hard coding for now.

        private async void ReferenceProjectDropDownList_SelectedValueChanged(object sender, EventArgs e)
        {
            if (null != _model)
            {
                BatchComparisonWaitingBar.Visibility = Telerik.WinControls.ElementVisibility.Visible;
                BatchComparisonWaitingBar.StartWaiting();
                BatchComparisonStatusLabel.Text = "Calculating gamma...";

                // calculate the passing % (gamma) for each item in the table
                await Task.Factory.StartNew(() =>
                {
                    for (int i = 0; i < _model.Scans.Count; i++)
                    {
                        //Thread.Sleep(500);
                        ComparisonScanViewModel sm = _model.Scans[i];
                        sm.Gamma =250m;
                    }
                });

                BatchComparisonWaitingBar.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
                BatchComparisonWaitingBar.StopWaiting();
                BatchComparisonStatusLabel.Text = "Ready";
            }
        }

When this event above is fired, the values in the model ARE updated; however, the results of this update are NOT reflected in the UI.  I have to scroll through the grid view and/or click on a row to see the value change in the grid.

Hi Team Telerik,

Hello team,
