New functionality allow you to save view state of controls of your web application during each callback. You can now work with View state during callback same as working with View State during post backs.
KCallback.net can AJAX enable standard ASP.NET controls and 3rd party controls.
You can save the state of all the form controls during callback request by setting the SaveState property to true.
Return callback result to a client-side function instead of rendering.
Return callback error to a client-side function for exception handling.
Override the callback contents both on the server-side and client-side.
Display an HTML block while processing the callback request.
KCallback.net can automatically disable selected controls during callback
Cache callback arguments and results on the client-side to improve performance.
You can pass multiple arguments into the Callback event handler and process them on the server-side.
Initiate callbacks automatically at specified intervals in milliseconds.
You can insert the KCallback.net control into a user control. So that you are able to run two instances of the same user control on the same page.
KCallback.net support client side function to handle the result and error for the callback response from the server.
Process callback request in the Callback event handler.
This allows you to alter/cancel the callback before and after execute client side event.

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