Hey everyone. I know this maybe a dumb question but I just started working with ASP.Net

My question is, How do I move from Page to page with certain information?

For example, when the user types its username and password, after checking that the information is correct, How do I take the user to the next page?

I'm using Visual Studio .Net and the validation part is easy but I don't know how to move from page to page.

I know this is a really dumb question, but if anybody could help I'd be really appreciated.

Thanx for any replies
