yes delete your list first if you want to update database.do compare and update in database.or make copy of your list before updating compare it.

well you can use static datatable in c# to bind data with the datagridview. in your case you are deleteing rows only and not the data so when you come back from one page to other your grid will bind again on the page load and it will bind data from the database.

instead of doing this get static datatable will help you to maintain the values of rows during the navigation from one page to other. so when you delete a row from gridview also delete from datatable.
however be care full when you use static variable incase you have a large amount of data. it will occupy a lot of memory..
