ASP.net Template

I am just starting to teach myself asp.net, and im going to work at rebuilding some of the database sites i have allready created.  Most of the sites i do now use a incheader.asp, and incfooter.asp.

Is there a way to make a template with asp.net.  A freind of mine said something about a  user control... Im just going to have to research it a bit more but thought I would just drop a question here.

Thanks.
