DevExpress MVC extensions fully support Ajax Forms.
This demo shows how to process a form asynchronously with results without a page reload. The partial view that contains DevExpress MVC Editors is reloaded only.
When end user clicks the "Process" button, the form is sent to a server via an ajax callback without page reloading.
In this demo, the Ajax Form is created using the Ajax.BeginForm() helper method.
You can find more information about Ajax Forms at MSDN Reference: AjaxExtensions.BeginForm Method.
