Add required to LabelFor

I'm having the following code: 

@Html.EditorFor(model => model.Title, new { htmlAttributes = new { @class = "form-control" } })

And I'm looking for a way to add the html attribute required to it, so a user can't submit without having the field filld. But now sure how to do? I know the easies way is to add required But don't know how, i tryed with @html "reguired" Without any luck.

EDIT: Answere = required = ""

You will need this for client validation

"~/Scripts/jquery.js"
, "~/Scripts/jquery.validate.js"
,"~/Scripts/jquery.validate.unobtrusive.js"

whereas for only server side on Controller or necessary even if some disables javascript

if (ModelState.IsValid)

As above using annotation

[Required(ErrorMessage = "Title is required")]
public string Title { get;set; }

Using Fluent API

    public class ClassNameConfiguration : EntityTypeConfiguration<ClassName>
    {
        public ClassNameConfiguration()
        {
            Property(x => x.Title).IsRequired();
        }
    }

You can add RequiredAttribute to your model property:

[Required(ErrorMessage = "Title is required")]
public string Title { get;set; }

And add ValidationMessageFor to your cshtml:

@Html.EditorFor(model => model.Title, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(m => m.Model)

Then add model validation to controller method via. It's the standard pipeline for asp.net mvc.

You also can implement your own HtmlHepler to add required attribute to your html code.
