I have an ASP.NET MVC application with quite a few drop-down lists and multi-select lists. Essentially, a lot of lists of options.

My question is; is it better to pass these lists to the view as part of the Model, or as ViewData?

I am currently passing them as ViewData as I don’t really need them on the model and they seem potentially bulky for passing around on the model (I get the selected item or items, which is really all I need). On the downside, ViewData needs casting on the View, which isn’t as nice as the strongly typed model.

Is there a best practice here? Even suggestions of pros and cons for either of these would be appreciated.

    I recommend you to use ViewModels to pass that data. It’s error prone to use ViewData with “magic strings” and I prefer to use intellisense instead of trying to remember that “magic strings”. And you don’t need to create that SelectLists in the controller. Just use some IEnumerable and use ToSelectList extension method from MvcContrib in the view.
