The DevExpress GridView does not have a Rows collection. You should instead loop through the rows with a for loop. See the Tutorial: Identifying Rows for more information about this. For example:
for (int i = 0; i < gridView1.RowCount; i++)
{
object barCodeValue = gridView1.GetRowCellValue(i, "Barcode");
}
Use the GridView's GetRowCellValue method to retrieve the value of a cell based on the field/column name and the row index.
Use the GridView's SetRowCellValue to set the value of a cell based on the field/column name and row index.
