asp.net mvc key Tutorial first-year fifth back ActionResult other return values

The action we see above is return View (), and we can look at it as a value for parsing an ASPX file. And its return type is actionresult as

public　ActionResult　Index()
{
return　View();
}

Besides view () what value can we use here to return?

One, ascx page

Scenario: To return a snippet of code, such as Ajax, to return a child page

Let's start with a new action.

public　ActionResult　Ascx()
{
return　PartialView ();
}

We'll build a view below, and still be right in the Action Center, AddView.

　

Note that the figure is checked.

So I created a new ascx page, and we'll rewrite it a little bit.

<%@　Control　 Language="C#"　Inherits="System.Web.Mvc.ViewUserControl"　%>

<div>
得到一个DIV
</div>

Run, get the page
