For the main part, the DataSource controls are incredibly easy to work with. You just drag them onto your page in Design View, wire them up to a connection and provide some kind of command (ad hoc sql query or the name of a stored procedure - saved query in Access), then link them to a databound control on the page using its DataSource property.

If you have centered web pages, there can be times where the depth of content doesn't reach the bottom of the window browser, so no scroll bar appears. Navigating between long and short pages can give the appearance of the centered content "jumping" from side to side.
