Web Forms :: Web Page That Allows Multiple Database Row Updates

We currently have a page with a listview control that has textboxes and an update button for each row. Users are able to update the database one row at a time.This is problematic in countries where the internet connections are very slow because a round trip is needed for each row update and this can become impossible to use.We need to create a page which allows multiple row updates so that each round trip is more productive. There woudl be just one update button on each page and users could enter values into each row. Clicking the update button would update each changed row
of the database.We currently use linq 2 sql. I would imagine that we could still use this in the above scenario??? Or is there a better data connection methode to use in this scenario.
