1) get the basic overview on .net technology and how it works..
2) get the knowledge on basic asp.net control
3) get overview and undrstanding of looping statement (if, for, foreach, case etc...)
4) then after one by one go and learn the concept like master page, user control, css, theme , skins etc...
5) After that you can learn the database connectivity.
6) develop few database related application
by doing in this way you will get more clear idea on .net
