Calculating a ASPxGridview Column in DevExpress
问题 I have a ASPxGridview (Normally 21 column but i just want process 4 column). Every column has a decimal value. MV_EDDIE column is empty. What i want is, calculating programmaticly , MV_EDDIE columns is RISK_EUR - (IPOTEK + MV_BERND) only in GroupSummary and TotalSummary . For example; If RISK_EUR = 100 IPOTEK = 40 MV_BERND = 50 Then MV_EDDIE column should be 100 - (40 + 50) = 10 How can i do that? NOTE : I have a Sql like this SELECT A.HESAP_NO, A.TEKLIF_NO1 || '/' || A.TEKLIF_NO2 AS TEKLIF,
