Disable form validation in MVC2

Is it possible to programatically disable form validation in MVC2?

I'm hoping there is some kind of command that I can put in a custom ActionMethodSelectorAttribute, making it possible to prefix ActionResults where I want form validation disabled.

The reason for this is that I have a form with multiple buttons, one button adds a new row to a child object of the model - which consequently creates a new row on the form.

This works fine, but va开发者_C百科lidation is fired for the form each time "add" is pressed, and so the new fields flag up validation errors before the user has a chance to enter data.

I've found an alternative solution to this.

Rather than use multiple form buttons, I've used a custom html helper which produces a "Add" link. This helper places the current Model in TempData and produces a Link to Add/{id}.

I'm not sure this is the cleanest solution, but it allows child elements to be added without validation firing. To tidy things up a bit, I specified the form as such:

Html.BeginForm(view, controller, new { id = Model.ID })
