I have tried the suggestions found here and elsewhere but still no joy!

DataTable dataTable = new DataTable();

      foreach (DataGridViewColumn col in dataGridView1.Columns)
      {
          dataTable.Columns.Add(col.Name);
      }

      foreach (DataGridViewRow row in dataGridView1.Rows)
      {
          DataRow drow = dataTable.NewRow();
          foreach (DataGridViewCell cell in row.Cells)
          {
              drow[cell.OwningColumn.Name] = cell.Value;
          }
            // The drow (DataRow) has all the Data in its ItemArray property but it does not get saved into the datatable row.
              dataTable.ImportRow(drow); // dataTable.Rows.Add(drow);
              dataTable.AcceptChanges();
            //The columns load but the data rows do not add or import

      }
