Even if they press F5 or Refresh within the browser all they obtain is a plain refresh of the page; no additional deletion of data occurs.

How can this code be improved to avoid a full page refresh without rewriting the entire application, or large portions of it, as a SPA?

For any browser-based application, it makes sense to load into the web page just the content that is immediately required and avoid whole-page refreshes whenever possible.

Ajax technology and JSON makes this partial-rendering easy. NET's own partial-rendering techniques, returning HTML. It requires less client-logic and is quicker to implement. By ‘classic web sites’ mean web sites where the vast majority of pages are being served entirely from the web server and fully refreshed after each postback.

In this case, the browser still receives text/html content but not necessarily HTML content that makes up an entire page.

As a result, if a URL that returns a partial view is directly invoked from the address bar of a browser, an incomplete page may be displayed.

Most commonly, partial views are used to componentize Razor views and make them easier to build and update.

Partial views can also be returned directly from controller methods.

Such data is then incorporated in the current DOM via HTML templates and libraries such as Knockout or Angular JS.You can also use j Query to place a POST request and receive back a plain ack message or some JSON data.All this is well-known and, for the most part, it is mainstream practice today.Some SPA purists may dislike this approach because-they may say-returning HTML is less efficient than returning plain JSON data. Still a bit of Java Script is required, but it is limited to using familiar DOM properties such as or just a few core j Query methods. NET MVC project with a Razor view that produces the output of Figure 1.True, but the techniques presented in this article are a lot smoother to implement in coding scenarios where the predominant skills are server-side ASP. The page contains a list of data elements that users can delete one by one by clicking a button. NET, you may have a HTML form all around the list and each of the delete buttons is implemented as a submit button. On the server you figure out which button was clicked, and from there you get the ID of the element to delete.

In the real-world, or at least in the section of the real world that I see every day, there are still plenty of classic ASP. The full refresh of the page after a postback can be significantly slow and cumbersome for users, especially when the use of graphics of these sites is quite heavy.
