Remarks

The AjaxHelper<TModel> class is a strongly typed class that derives from the AjaxHelper class. The AjaxHelper class includes methods that provide client-side functionality in ASP.NET AJAX in MVC applications, such as creating asynchronous forms and rendering links. The AjaxHelper class supports asynchronous partial-page updates. Extensions to the AjaxHelper class are in the System.Web.Mvc.Ajax namespace.

Helper methods and extensions are called by using the Ajax property of the view, which is an instance of the AjaxHelper class. For example, to generate a link to a controller action method, you call the ActionLink method in your view using the following syntax

<%= Ajax.ActionLink("ActionName") %>

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
