I have a web form with a detail and a list view on it, the user fills the data in the fields of the detail view and then presses the "save" button, and everything is ok for the moment.
However, if they press F5 after this operation a new record is going to be inserted in the DB, because the postback is repeated.
Does anybody knows how this could be avoided?
