ModelState.AddModelError on form level with ASP.NET MVC 2 RC

Question

In the previous versions on ASP.NET MVC, you could use ModelState.AddModelError("**_FORM**", "error") to make an error on the form-level instead of a property-level. This seems not to work anymore with the new RC of ASP.NET MVC 2.

Is there another way how to do it? I use <%= Html.ValidationSummary() %> at my View-file...

I personally use AddModelError("" - I don't know where does _FORM come from? - and ValidationSummary() is no black magic - I use my own helper instead that, for example, includes specific (user-specific) exceptions messages into output. The helper is very easy to write - a simple foreach loop over ModelState - so you may consider writing your own one. There you're free to show form-level, property-level, or whatever you like.

I did try AddModelError(null, ... but that didn't work. AddModelError("", ... is working like a charm! Thank you! – Jeff Maes Feb 09 '10 at 07:28

the error are inside modelstate and is send to the helper class of validationsummary by following argument:

this.ViewData.ModelState.Keys

this.ViewData.ModelState.Values
