使用XtraGrid自定义列计算1 z

if (e.IsTotalSummary && e.SummaryProcess == DevExpress.Data.CustomSummaryProcess.Finalize)
            {
                GridView view = sender as GridView;
                if (e.Item == view.Columns["Price"].SummaryItem)
                {
                    int count = 0;
                    for (int i = 0; i < view.DataRowCount; i++)
                    {
                        object temp = view.GetRowCellValue(e.RowHandle, "Price");
                        temp = (temp == DBNull.Value || temp == null) ? 0 : temp;
                        count += Convert.ToInt32(temp);
                    }
                    e.TotalValue = count + 10;
                }
            }
