Benefits

1 No need to learn how AJAX works

you don't have to know AJAX in order to use AJAX. The postback behavior of the selected elements is automatically replaced with AJAX callbacks and the typical challenges of AJAX development are handled internally. So there is less to learn and less to worry about.

2 Improved User Experience

KCallback.net handles page update with AJAX-based callback requests, instead of complete postbacks. As a result there is no loss of scroll position, with only the relevant elements being updated just like in Windows applications. This leads to smoother interface transitions and superior user experience. The KCallback.net can handle even the most complex scenarios and offers a number of advantages compared to other solutions.

3 No Need to Write Complex JavaScript

KCallback.net eliminates the need for writing the complex JavaScript required for updating interface elements of AJAX-enabled ASP.NET applications.

4 Design-time Support

Due to the fact that KCallback.net can update standard ASP.NET controls without using callback wrappers, development of AJAX enabled ASP.NET application is exactly similar to any standard ASP.NET application, which makes design and deployment a breeze for you and your team.

5 No Need for Callback Wrappers

A major advantage of the KCallback.net control is that it can update the standard ASP.NET controls without using callback wrappers/placeholders, which define the parts of the page that have to be updated. The KCallback.net control automatically detect all page modifications and update the relevant controls. This significantly minimizes the amount of changes you have to make to existing applications in order to implement the AJAX functionality.

6 Cross-Browser Support

KCallback.net works on all browsers that support XmlHttpRequest (IE5+, NS7+, Firefox 1.0+, Mozilla 1.0+, Opera 8+).
