how to change the value of a cell?

I am doing an application that consists in a DataGrid filled only with numbers, every time that you touch a cell the value of the cell will increase one at once, when I touch the cell the application crash.

I was doing the same in Xamarin.Forms, but the application not crashed.

This is the event Tapped

private void GrdCountConcept_GridTapped(object sender, GridTappedEventArgs e)

            int rowIndex = e.RowColumnIndex.RowIndex;
            int columnIndex = e.RowColumnIndex.ColumnIndex;

            List<OrderInfo> source = (grdCountConcept.ItemsSource as List<OrderInfo>).ToList();

            if (columnIndex == 0)
                grdCountConcept.ItemsSource = source;
                var recordData = grdCountConcept.GetRecordAtRowIndex(rowIndex);
                string columnName = grdCountConcept.Columns[columnIndex].MappingName;

                int cellValue = Convert.ToInt16(grdCountConcept.GetCellValue(recordData, columnName));


                switch (columnIndex)
                    case 1:
                        source[rowIndex - 1].Talla4 = cellValue;
                    case 2:
                        source[rowIndex - 1].Talla6 = cellValue;
                    case 3:
                        source[rowIndex - 1].Talla8 = cellValue;
                    case 4:
                        source[rowIndex - 1].Talla10 = cellValue;

                grdCountConcept.ItemsSource = source;

Where OrderInfo only has int values
