Do you happened to have a form, like a Customer File form or something like that, with navigating buttons (Next/Previous)? If so, how do you deal with database connection in this form (again, if you have such a thing).

Thank you.

>I open the connection and leave it open until I've download/upload all the data I need from the server, then I close it. with this method connectiing time is not an issue (at least not for me).

As user navigates through records in the table, the cycle "UI->BO->DA" will be done quite often (possibly). The DA is where connection to SQL Server takes place.
