Hi guys,
i have asp.net web application using c# & sql server 2008 as Database.
i have a repeater, where i have checkbox and chemical name.
it will save those which are selected, till here its ok.
but, in updating, i'm getting a problem.
if user selected 1, 2, 3 and save. instead of 1,3,4 the user selected 1,2,3.
now he want to update it.
while updating, if the record does not exists it will insert.
but, how to remove record which were not selected,
bcoz it was not selected while updating...
(insertion/update will trigger only if its selected/checked)
can anyone please help me.
thanks
