Guide line require for designing interactive form

Guide line require for designing interactive form

my web site is cms driven. we have html editor and we generate page
content with editor and save in database. when user request content.aspx
with id=20 or id=50 then we pull html from db and show in page. but our
web site has some input form where user give input and just send. whenever
we need to create new input form or modify existing then we need to upload
aspx & dll to our web server and it is really tedious for us.
1) so i am looking for good guide line that how to develop input form as a
result when we develop any new or modify any existing then we do not need
to upload aspx & dll file to our web server. i like to know what is the
latest trend which i can use to develop input form as a result we never
need to upload aspx & dll file to our web server after any change.
2) how can i develop our web site in such a way as a result admin can
change anything like page content or menu content, add new menu, develop
new page etc.
looking for great discussion. thanks
