ASP.NET MVC3剃刀：从管窥重定向 [英] ASP.NET MVC3 RAZOR: Redirecting from Partial Views
问题描述
我有两个部分的意见MyPopular和MyBlogs。并有两个控制器 - ArticleController.cs和ThePopularController.cs。这两个partialviews包含按钮。
起初，它呈现指数视图内两个部分景色。
在后期操作处理程序博客的点击，它被要求重定向到BlogHome行动在那里它会返回一个简单的字符串博客之家（而不是一个视图）。在后期操作处理程序流行的点击，它被要求重定向到PopularHome行动在那里它会返回一个简单的字符串流行的家庭。但是目前，当我点击任何按钮，这使得本地主机：1988 /条指数;没有部分内容。
注：结果是一样的，即使我用ContentResult类型和的ActionResult。 注：请突出，如果我经历了错误的方式实现这样一个简单的任务。
我们如何纠正它做了正确的重定向？

有号在你code错误的：
- 当调用子操作
MyBlogs从家长行动首页，有@using（HTML .BeginForm（））在MyBlogs视图，生成形式职位首页操作，不是MyBlogs一个。同样的故事Populars。因此，没有惊喜，每一个提交重新呈现指数作用的内容 - 这是你的形式要求的动作。尝试使用Html.BeginForm接受路由参数的过载。 -
[ChildActionOnly]意味着动作不会被外界访问，是要求HTTPGET，邮政，通过网址或其他任何方式。它只能用于与Html.Action帮手。所以，当你纠正错误一日，你会不会依然能够张贴在行动。您应该删除ChildActionOnly属性，如果该操作应处理POST请求。 - 如果是c您发布真正的$ C $，它没有（也不应该）重定向。你应该正确的方法签名，并添加缺少的
返回语句
这code
[HttpPost]
公共无效MyBlogs（字符串blogclick）
{
RedirectToAction（BlogHome）;
}
应
[HttpPost]
公众的ActionResult MyBlogs（字符串blogclick）
{
返回RedirectToAction（BlogHome）;
}
这应该工作
I have two partial views "MyPopular" and "MyBlogs". And there are two controllers – "ArticleController.cs" and "ThePopularController.cs". Both these partialviews contains buttons.
Initially it renders both partial views inside the index view.
On post action handler for blog’s click, it is asked to redirect to "BlogHome" action where it will return a simple string "Blog Home" (instead of a view). On post action handler for popular’s click, it is asked to redirect to "PopularHome" action where it will return a simple string "Popular Home". But currently, when I click on any of the button, it renders localhost:1988/Article index; without partial content.
Note: The result is same even when I used ContentResult and ActionResult. Note: Please highlight if I am going through the wrong way for achieving such a simple task.
How do we correct it to do the proper redirecting?
//ArticleController
public class ArticleController : Controller

//Index returns no model
return View();
}

return "Blog Home";

Thread.Sleep(500);

There are number of errors in you code:
- When calling child action
MyBlogsfrom parent actionIndex, having@using (Html.BeginForm())in the MyBlogs view, generates the form that posts toIndexaction, not theMyBlogsone. Same story forPopulars. So, no suprise that every submit re-renders Index action contents - that is action requested by your form. Try using overload of Html.BeginForm that accepts route parameters. [ChildActionOnly]means that action is not accessible by outside world, be request HttpGet, Post, by url or any other means. It can be used only withHtml.Actionhelper. So, when you correct the 1st error, you won't be still able to post on that action. You should removeChildActionOnlyattribute if that action should handle post requests.- If it's the real code you posted, it does not (and should not) redirect. You should correct method signature and add missing
returnstatement
This code
[HttpPost]
public void MyBlogs(string blogclick)
{
RedirectToAction("BlogHome");
}
Should be
[HttpPost]
public ActionResult MyBlogs(string blogclick)
{
return RedirectToAction("BlogHome");
}
This should work
