DataTemplate _dt = (DataTemplate)XamlReader.Load(
                    @"<DataTemplate
                xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"" xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml"" xmlns:local=""clr-namespace:Cognizant.Ace.Pmo.Silverlight"">

                <TextBox Text=""{Binding period,Converter={StaticResource GridEditFormatter},ConverterParameter='" +  _dayBE.date + @"',Mode=TwoWay}""/>
              </DataTemplate>"
                    );
                gvdc.CellEditTemplate = _dt;


//Convertor is as follows-----------------------
public class GridEditFormatter : IValueConverter
    {
        private ObservableCollection<DayBE> _daysBE;

        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            _daysBE = value as ObservableCollection<DayBE>;
            if (_daysBE.SingleOrDefault(x => x.date == System.Convert.ToDateTime(parameter.ToString()))!=null)
            {
                return _daysBE.SingleOrDefault(x => x.date == System.Convert.ToDateTime(parameter.ToString())).allocation;
            }
            return 0;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            DayBE _editedDay = new DayBE();
            _editedDay.date = System.Convert.ToDateTime(parameter.ToString());
            _editedDay.allocation = System.Convert.ToDouble(value);

            if (_daysBE.SingleOrDefault(x => x.date == _editedDay.date) != null)
                _daysBE.Remove(_daysBE.Single(x => x.date == _editedDay.date));

            _daysBE.Add(_editedDay);
            return _daysBE;
        }
    }

Hello,

Will it be possible for you to send a simple runnable project demonstrating it so we can debug it locally to check what happens? You can take a look at this blog post for a reference on how to isolate a problem in a sample project.
