We are running ASP.net 2.0 on both a development machine and a production server. The same code works fine on the development machine and the client-side validators appear as they should. But on the production server, no client-side validation occurs. Server-side kicks in when the page is submitted, but I'd really like the client-side to work as well. There is no difference between the development and production configuration that I'm aware of, but I'm not exactly sure what to be looking for. Both are using 2.0 framework and should not need the client scripts that were in aspnet_client under 1.1. Any ideas what difference I should look for on the production machine? Thanks!
