Add to LabelFor

Question

I have 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 to it required, so the user cannot send without filling the filld field. But now sure how to do it? I know the easy way is to add requiredBut I don't know how, I tried using @html "reguired"No luck.

EDIT: Answere = required = ""

Answer 1

You can add RequiredAttribute to the 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 the controller method via . This is the standard pipeline for asp.net mvc.
