MVC3 - 传递数据超出了模型局部视图 [英] MVC3 - Passing data beyond the model to Partial view

问题描述

有没有办法通过一块额外的数据与模型的局部视图沿？

Is there a way to pass a piece of extra data along with a model to a Partial view?

例如

@ Html.Partial（_ SomeTable（列表＆LT; CustomTable＆GT;）ViewBag.Table）;

是我现在有。我可以添加别的东西不改变我的模型？

Is what I have now. Can I add something else without changing my Model?

@ Html.Partial（_ SomeTable（列表＆LT; CustomTable＆GT;）ViewBag.TableTemporaryTable）;

我看<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.mvc.viewdatadictionary.aspx\">ViewDataDictionary作为一个参数。我不知道这个对象做什么，或者这符合我的需要。

I see ViewDataDictionary as a param. I am not sure what this object does or if this meets my need.

推荐答案

的ViewDataDictionary可以用来取代ViewData字典中的局部视图...如果你没有传递的ViewDataDictionary参数则parial的可视数据是一样的家长。

ViewDataDictionary can be used to replace the ViewData dictionary in the partial view... If you don't pass a ViewDataDictionary parameter then the parial's viewdata is the same as the parents.

如何在父使用它的一个例子是：

An example of how to use it in the parent is:

@Html.Partial("_SomeTable", (List<CustomTable>)ViewBag.Table, new ViewDataDictionary {{ "Key", obj }});

然后内的部分你可以访问此OBJ如下：

Then within the partial you can access this obj as follows:

@{ var obj = ViewData["key"]; }

一个完全不同的方法woud是使用元组类组中的两个原始模型和额外数据一起如下：

A completely different approach woud be to use the Tuple class to group both the original model and extra data together as follows:

@Html.Partial("_SomeTable", Tuple.Create<List<CustomTable>, string>((List<CustomTable>)ViewBag.Table, "Extra data"));

为偏模型类型随后将是：

The model type for the partial would then be:

@model Tuple<List<CustomTable>, string>

Model.Item1给List对象和Model.Item2给出字符串

Model.Item1 gives the List object and Model.Item2 gives the string
