Answer 1

Got It.

In ASP.NET MVC 2 RC, It is PropertyValueInvalid, not InvalidPropertyValue.

Answer 2

I don't know about v2, but this works on v1:

1. Add a resource file in App_GlobalResources.
2. In the resource file you can define strings named PropertyValueInvalid and PropertyValueRequired.
3. On the Application_Start global.asax event set System.Web.Mvc.DefaultModelBinder.ResourceClassKey = "resource file name".

Thank you for your answer, but for some reason it doesn't work. Maybe there is a different way to do it on mvc 2. – Stifling

You can find out using Reflector. – Thumbsdown

Answer 3

Try using: <%= Html.ValidationMessage("Price") %> without the star "*".

I consider this one the best approach. (+1). User messages belongs to Views, not to Controller. If in future you want to create the same page in another language, you will keep the same controllers and change ONLY the views. – Amin

Cynthia, try to add this into your web.config

  <compilation debug="true" targetFramework="4.0">
      <buildProviders>
        <add extension=".resx" type="System.Web.Compilation.ResXBuildProvider"/>
        <add extension=".resources" type="System.Web.Compilation.ResourcesBuildProvider"/>
      </buildProviders>
  </compilation>

MVC calls httpContext.GetGlobalResourceObject(ResourceClassKey, "InvalidPropertyValue", CultureInfo.CurrentUICulture) to find the message, and sometimes you must add those providers to GetGlobalResourceObject find the correct resource
