Addind css classes to razor elements

Question

In razor if I had something like:

@Html.EditorFor(model => model.name) or even: @Html.CheckBoxFor(m => m.RememberMe)

How woul

Answer 1

Because EditorFor isn't type-specific, you can't use it on those.

For CheckBoxFor, you can use:

@Html.CheckBoxFor(m => m.RememberMe, new { @class = "myClass", id = "myID" })

Note the @ before class because that's a reserved keyword in C#

Answer 2

It's easy for CheckboxFor, you can do it like this:

@Html.CheckBoxFor(m => m.RememberMe, new { @class="your_class", @id="the_id" })

It's a bit trickier with EditorFor as it is NOT supported out of the box. What I mean is you can create a template for each type and then do a TextBoxFor adding html attributes (same syntax as with CheckBoxFor). You may have to do it for each type you want supported.

Answer 3

You cannot do that with the EditorFor helper simply because you don't know what template will be used. You could achieve it but you will need to write a custom editor template. For example this could be achieved by overriding the default editor template and taking into account the second parameter which represents an additional view data.

Here's an example of how such a custom editor template could look for string types (~/Views/Shared/EditorTemplates/string.cshtml):

@Html.TextBox(
    "", 
    ViewData.TemplateInfo.FormattedModelValue,
    ViewData
)

and then you could use it like that:

@Html.EditorFor(model => model.name, new { @class = "myclass" })

With the CheckBoxFor helper you could do that:

@Html.CheckBoxFor(m => m.RememberMe, new { @class = "myclass" })
