I have created a form with grid. In this grid i am entering a new values for the fields projid,loa number etc .After that i made allow edit to be no for the above fields so that it will not allow edit after save. But there is another field called Return Date in the same grid line… I made it enable since the user will fill the date field later. But after saving the date field for the first time in the line ,then return date field also to be disabled. Please let me know how can we do this? Please let me know if my query is not clear.
