I have a curious issue when adding a new row to a BO. I perform a BO.Add() function, then I overwrite the firlds in the row with data from the screen manually followed by a BO.Save(). When I interrogate the datatable I find that the current row has been changed with the data I have just input and a new row of zeroes appended to the same table. It looks as if the .Add() has put the current row into Edit mode. Can anyone please advise, many thanks.
