            this.DataContext = custsInCA;
            this.CustomerView = ((BindingListCollectionView)(CollectionViewSource.GetDefaultView(this.DataContext)));
        }

        //public string value { get; set; }
    }

    public class ImageDataConverter : IValueConverter
    {

         public object Convert(object value, Type targetType, object parameter,

         System.Globalization.CultureInfo culture)
         {

            //System.Data.Linq.Binary binaryData = value;// here there is the first error .How convert BinaryData to Object??
            if (binaryData == null)
