title: asp.net observer pattern
body: <p>I'm working on a project where a central class (the subject), will contain alot of data. There will be an aspx page that displays this data, using .net ajax. When the subject is updated from any page, I want all the open pages to update. I will be using the observer pattern for this. THe question is, do I make the actual aspx page the observer, or is there a better way to do this?</p>
