I use devexpress gridControl , i do fill gridcontrol from database,
i did add new column containt differnt value (tow column)
A new column is added that contains the difference between the two columns values (sum(depit)-sum(credit)).

i try passing all data in gridcontrol to another gridview or another form or report , but i can not passing data in the new column that contains the difference between the values of the two columns .
