Answer 1

Look at how FormCollection is used here: http://stackoverflow.com/questions/762825/how-can-a-formcollection-be-enumerated-in-asp-net-mvc

Answer 2

Just to make a few comments, 1. dinner.EventDate = DateTime.Parse(Request.Form["EventDate"]); is what model binding is supposed to get rid of. Using a strongly typed view, you should get a DateTime type back into dinner.EventDate, without having to do that assigning yourself. 2. The FormCollection returns all the input's that were submitted via the html form and you are able to retrieve those elements by using the following syntax formCollection["Title"] given that the input element's name is "Title"

Strongly typed views are just amazing!
