Answer Posted / umar topia
Have one column with in Database table with datatype as
TimeStamp and while selecting the row we will read the
TimeStamp value, which we can compare at the time of updation,
if both values are same then we can update that row
otherwise we can resist the user from updating saying that
someone has updated the row, you can't update it.
