How do I edit the CSS of the Html.DisplayFor method in MVC 3?
提问by barnone
I am using the following code to display text from my view model in my view:
我正在使用以下代码在我的视图中显示来自我的视图模型的文本:
@Html.DisplayFor(m => m.Name)
When I look at the HTML details in IE9 (which I have to use at work) there is no class associated with the name, it just uses the Body CSS styling instead of the display-field class styling. Does anyone know what might be causing this issue or how I might edit the CSS for the text created?
当我查看 IE9 中的 HTML 详细信息(我必须在工作中使用)时,没有与名称关联的类,它只使用 Body CSS 样式而不是显示字段类样式。有谁知道是什么导致了这个问题,或者我如何为创建的文本编辑 CSS?

DisplayFor is used for templating reasons. If you aren't using a template, then you should just use the item like so: @Model.NameIf you want to give it a class or id, then you need to wrap it in a span or div.
DisplayFor 用于模板化原因。如果您没有使用模板,那么您应该像这样使用项目:@Model.Name如果您想给它一个类或 id,那么您需要将它包装在一个 span 或 div 中。
Your problem is that you're using the wrong method to output data, and expecting it to do something else. There is no built-in way to output raw data with class names.
您的问题是您使用错误的方法输出数据,并期望它做其他事情。没有使用类名输出原始数据的内置方法。
So your choices are, wrap the raw item in a container that you can apply the css to, or create a template to use for these, then specify the template name in the DisplayFor like so:
所以您的选择是,将原始项目包装在一个容器中,您可以将 css 应用到该容器中,或者创建一个用于这些的模板,然后在 DisplayFor 中指定模板名称,如下所示:
@Html.DisplayFor(m => m.Name, "NameTemplate")
回答by Dmitry Efimenko
if it is a label, use proper helper for it as Nataka526 suggests
如果它是一个标签,请按照 Nataka526 的建议使用适当的帮助程序
otherwise put it in a span with a class and update css for that class:
否则将它放在一个带有类的跨度中并为该类更新 css:
your html:
你的html:
<span class="name">
@Html.DisplayFor(m => m.Name)
</span>
your css:
你的CSS:
.name {
//custom css
}
UPDATE
更新
Another option: Update your Display Templates to handle a specific ViewData key:
另一种选择:更新您的显示模板以处理特定的 ViewData 键:
in Views > Shared > DisplayTemplate (create this folder if you don't have it already):
在“视图”>“共享”>“显示模板”中(如果您还没有此文件夹,请创建它):
add file String.cshtml:
添加文件 String.cshtml:
@model string
@{
string myClass = ViewData["class"]
}
@if(string.IsNullOrEmpty(myClass))
{
@:@Model
}
else
{
<span class="@myClass">@Model</span>
}
you may need to add DisplayTemplates for other tipes as well besides string.
除了字符串之外,您可能还需要为其他提示添加 DisplayTemplates。
In the view you will write something like this:
在视图中,您将编写如下内容:
@Html.DisplayFor(m => m.Name, new { @class= "name" })
This will add spans around it automatically.
这将自动在它周围添加跨度。

Explanation:
解释:
There is an overload on Html.DisplayForwhich accepts two parameters: expression and object additionalViewData. So the second parameter that I pass is that anonymous object additionalViewData. I create this object with property called class
有一个Html.DisplayFor接受两个参数的重载:表达式和object additionalViewData。所以我传递的第二个参数是匿名对象 additionalViewData。我用名为的属性创建了这个对象class
Inside of the html helper I then check if there is a ViewData with a key classand if there is, I put output inside a span with that class value.
在 html helper 内部,然后我检查是否有带有键的 ViewData,class如果有,我将输出放在具有该类值的范围内。
**
updated variable name from classto myClasssince "class" is not appropriate variable name.
** 更新了变量名class,myClass因为“类”不是合适的变量名。
