When I use the required field validator does this perform a round trip to the server or does it all stay on the client without ever hitting the server?I *think* I can answer this one.<BR><BR>It depends upon the client browser.<BR><BR>If the browser supports javascript, client-side valiation will be built to check the field to make sure something has been entered.<BR><BR>Validation is then (always) done server side, regardless of the browser used.<BR><BR>Hope this helps
