If you render a Link to another Controller / View, you can just use the method 'Html.ActionLink' on a view. If you want to submit additional parameters / action parameters in the link, you can use the overloads of 'Html.ActionLink'.
If you want to display a IEnumerable<x> List in a View, you cannot use standard ASP.NET WebForms Controls like a ListView to iterate over a list. The reason here is mostly because of the fact that MVC 2 does not implement the Form-ViewState.
