Question

The customer has a Model property that requires a comma separated list of selected options. We present their select list (DDL) as a multi-choice drop down.

What would the property datatype look like that would autobind multi-selections in the client side HTML select (DDL)?

The select posts data like this:

myOptions=Volvo&myOptions=Mercedes&myOptions=Audi

And we want to automagically bind it back to some property:

IList<string> CarChoices {get;set;}

So the POST action method parameter would be (Carform myForm)
which would have myForm.CarChoices which includes a List of the three selected cars?

I might be misunderstanding what you’re trying to accomplish but I think this post from Phil Haack describes how to do what you’re attempting to do in a clean way: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx
