Re: How to delete record from Datagrid and not from Database

Nov 14th, 2006

man

i think to do that, you should after retrieving data from db, copy ur datasource to a session and then to datagrid.

then man if u want to delete from the datagrid only, you should delete from the session and rebind the datagrid to the session,

in this way, u didnt delete anything from db.

try it and tell us.
