How to Use ajax in the asp.net mvc project?

The official CTP version of ASP. net mvc framework does not include AJAX support. However, several examples show how to add AJAX for ASP. net mvc applications.

Example:

Public class TaskListController:AjaxController{
Public void Add (string name ){
Task newTask = null;
If (String. IsNullOrEmpty (name) = false ){
NewTask = _ taskDB. AddTask (name );
}
If (IsAjaxRequest ){
If (newTask! = Null ){
RenderPartial ("TaskView", newTask );
}
}Else {
[...]
}
}
}

AjaxaController is a Class I added. It introduces a new attribute IsAjaxRequest. I can use it in the Action method to do something like output different views. It also introduces other members, such as the RenderPartial method, which can generate a part of the user interface by defining the content in a partial view instead of a complete page. The following is my new Controller and the new Add method. In addition to Controller extensions, Nikhil also provides some extension methods for the view to use: "RenderBeginForm is used to generate a common Form label, renderBeginAjaxForm generates an AJAX available Form [...], and the rendform method ". This example shows the first step of using the core AJAX functions of ASP. NET pages-partial refresh, Behaviors, and Extender controls ".
