I'm trying to create a user web control which takes a picture as a
background and draws a line on it according to user parameters. This web
control is supposed to appear on the page a few times and each page supposed
to be viewed by a dozens of users simultaneous.

by default new aspnet webforms inherits from page which gives us the
intellisense of the basic objects such as request, response etc.
I want my pages to inherit from another simple webform that I created but
then in these pages I lose this basic intellisense. any ideas?
