Adding a required indicator in ASP.NET MVC3 using jQuery

You might want to indicate that fields in ASP.NET MVC3 is required visually.

Sample image

It’s easy thanks to the HTML attributes that the unobtrusive validation API generates.

Start by adding a new CSS class in your site.css called something like .required-indicator.

.required-indicator { color: red; font-size: 1.2em; font-weight: bold; }

Then add a small jQuery script somewhere (in the layout or an application.js):

$(function() {
    $('[data-val-required]').after('<span class="required-indicator">*</span>');

Done! Here is a sample fiddle.
