Adding a CSS class to razor @Html.DisplayFor

问题

I want to set a new class for this part of my code, but it doesn't work correctly

@Html.DisplayFor(model => model.melk.Code, new { @class = "myClass" } )

Can anyone tell me where am I wrong?

回答1:

The DisplayExtensions.DisplayFor overload that you are using will find the DisplayTemplate based on the type of the model.melk.Code and the last parameter (anonymous object new { @class = "myClass" } will be passed to the template's ViewData. You have to use that ViewData in the corresponding template in order for it to work.

<div class="@(ViewData["class"])"...

Boris showed you the correct overload, but there is also the dead simple way to just change it to:

<span class="myClass">
    @Html.DisplayFor(model => model.melk.Code)
</span>

Personally, I find it simpler, so easier to remember and maintain, even if it's not so framework-specific.
