在ASP.NET MVC3局部视图无法访问ViewBag [英] Can't access ViewBag in a partial view in ASP.NET MVC3

问题描述

我有一个控制器调用视图。在视图中有一个 PartialView 称为为 @ Html.Partial（视图名，模型）。这工作正常

I have a controller calling a view. In the view there is a PartialView called be @Html.Partial("ViewName", model). This works fine.

而在控制器我想提出一些在viewbag这将是难以用我传递给视图的视图模型。
主要看有没有问题访问 ViewBag ，而在 PartialView 它不会返回任何东西。

But in the controller I wish to put something in the viewbag what would be hard to put in the viewmodel I pass to the view. The main view have no problem accessing the ViewBag, but in the PartialView it does not return anything.

是否有可能在这种情况下使用 ViewBag 或者我应该黑客这个数据为我传递到视图的模型（该模型我传递给 PartialView ，我传递给模型 PartialView 嵌套在第一个 PartialView ）？

Is it possible to use the ViewBag in this case or should I "hack" this data into the model I pass to the view (and the model I pass to the PartialView, and the model I pass to the PartialView nested in the first PartialView)?

推荐答案

这应该没有任何问题。在我的HomeController中Index操作我想补充一个信息，ViewBag：

That should work without any problems. In my HomeController Index action I add a message to the ViewBag:

ViewBag.Message = "Welcome to ASP.NET MVC!";

在索引视图我添加了局部视图：

On the Index View I add the partial view:

@Html.Partial("ViewName")

而在局部视图我呈现消息：

And on the partial view I render the message:

@ViewBag.Message

完美的作品。你还干了什么？可能是打错了？

Works perfectly. What else did you do? Might be a typing mistake?
