Coming from the desire to not use a ASP.NET Wizard Step which will require refactoring a ton of markup into ASP controls, I'm wondering if there is a pure JavaScript solution to do something similar to that of a Wizard Step?
Essentially, I want to have one screen then use something like ajax on a button "Next" click to simply update the markup inside of the main content area without the screen flicker I would see if I used the same template on the first page, then link to the second. One bonus would be that the content-to-come isn't visible when you "Inspect Element" or view source in the browser.
And a side question: Outside of ASP.NET land what is this behavior called?
