var cellValue = view.GetRowCellValue(index, "Mode");
if (BaseEdit.IsNotLoadedValue(cellValue)) {

#Example
The code sample below iterates through grid records and reduces the “Price” column values by 10 percent.
private void UpdatePrice(DevExpress.XtraGrid.Views.Base.ColumnView View) {
// Obtain the Price column.
DevExpress.XtraGrid.Columns.GridColumn col = View.Columns.ColumnByFieldName("Price");
if (col == null) return;
View.BeginSort();
try {
// Obtain the number of data rows.
int dataRowCount = View.DataRowCount;
// Traverse data rows and change the Price field values.
for (int i = 0; i < dataRowCount; i++) {
object cellValue = View.GetRowCellValue(i, col);
double newValue = Convert.ToDouble(cellValue) * 0.9;
View.SetRowCellValue(i, col, newValue);
}
} finally { View.EndSort(); }
}
