儿童的行为是不允许进行重定向操作 - 误差ASP.NET MVC 2和剃刀工作时 [英] Child actions are not allowed to perform redirect actions - error while working with ASP.NET MVC 2 and Razor

问题描述

在 _Layout.cshtml 文件我有以下项：

@Html.Action("LoadPagesStructure", "Page")

在的PageController 类， LoadPagesStructure methos看起来如下：

Inside PageController class, LoadPagesStructure methos looks following:

[ChildActionOnly] /* this attribute indicates that an action should not 
                     be invoked as a result of a user request (by url) */
public ActionResult LoadPagesStructure()
{         
    ViewModel.Pages = new List<string>() {"page1", "page2", "page3"};
    return View();
}

最后，我的 LoadPagesStructure.cshtml视图看起来像如下：

@inherits System.Web.Mvc.WebViewPage<dynamic>

<ul>
    @foreach (var page in View.Pages) {
    <li>        
        @Html.ActionLink(page, "Index", "Home")
    </li>
    }
</ul>

不幸的是，一个异常被执行后抛出：

Unfortunately, an exception is thrown after execution:

System.InvalidOperationException: Child actions are not allowed to perform redirect actions.

什么是创建链接动态我的网页的方式？

What is the way of creating links to my pages dynamically ?

PS：我知道我能做到这一点这样的：＆LT; A HREF =@页＆GT; @网页＆LT; / A＆GT; 。不过我认为这是不正确的做法，因为路由的控制是不可能在这里。

PS: I know that I can do this like that: <a href="@page">@page</a>. Nevertheless I think this is not the right way, because control of the routing is impossible here.

问候

推荐答案

我想你可能需要返回一个 PartialView 您 LoadPagesStructure（） 操作。

I think you might need to return a PartialView for your LoadPagesStructure() action.

试试这个：

[ChildActionOnly]
public ActionResult LoadPagesStructure()
{         
    ViewModel.Pages = new List<string>() {"page1", "page2", "page3"};
    return PartialView();
}
