public class StockDataPoint
{
    public DateTime Date { get; set; }
    [StringLength(5, ErrorMessage = "length no more than 5")]
    public string Color { get; set; }

    public double Close { get; set; }

    public int Volume { get; set; }

    public double Open { get; set; }

    public double High { get; set; }

View:grid to show and edit data

@(Html.Kendo().Grid<ChartServerGrouping.Models.StockDataPoint>()
 .Name("DataGrid")

      columns.Command(command =>
        {
         command.Edit().UpdateText("Save");
         }).Width(160); })
