Displaying an asterix when using Html.LabelFor() with a Required property

I'm using ASP.NET MVC2 and Data Annotations.

I've decorated a property in my buddy class with the Required attribute.

Is there a way to get the Html.LabelFor() helper method to automatically display an asterix to signify that the field is required?

Only ways I can think of to do this are:

a) Extend LabelExtensions

Or

b) Manually add the asterix to the DisplayName attribute, e.g. "My Field *"

The latter is simplest, but introduces a dependency between the DisplayName and Required attributes.

Any other suggestions?

Instead of using the Html.LabelFor, you should create your own view helper which will create the label and insert the * is appropriate. You can find detailed info about how to create a new view helper (which is very easy) at http://mvcviewhelpers.codeplex.com/.

You need to create your own default templates. This article series by Brad Wilson explains how to do this:
