I've been playing around asp.net mvc just recently, i was really shocked and somewhat struggling with this new framework since i was used to the traditional N-Tier development with asp.net. As I developed simple examples, asp.net mvc is somewhat similar to n-tier development. As such, each layers have been separated to enable designers and coders to work independently with each layer. I have some books in my arsenal but i haven't read them yet.LOL Basically, I'm still a newbie with this stuff. One tip that i read was choosing between asp.net webforms and asp.net mvc.

One weird error i encountered is that, it does not redirect to my index page once login has been successful. I implemented my own validation function to check if a user exists in the database. If the method returns true, redirect to index page. See code below. But the fact is, it does not redirect. if (CheckUserInMyDB(Login1.UserName, Login1.Password)) { e.Authenticated = true ; Login1.Visible = false ; Response.Redirect( "Index.aspx" ); } else { e.Authenticated = false ; } So the solution i found in forums.asp.net was to transfer the Response.Redirect to Logged in method of the login control.
