Using HTML forms in ASP.NET MVC?

Question

It seems like everything I look up on this subject has either changed since the release or is wildly different from eachother.

I just want to create a simple form in my view.

Should I be using the Html.BeginForm()/TextBox()/EndForm() methods or should I be using a plain-jane HTML form? Which is preferred?

This is what I have so far:

<%=Html.BeginForm("Create", "Product", FormMethod.Post); %>  
    <%=Html.TextBox("productTextBox", "Enter a shoe name"); %>  
    <input type="submit" name="createButton" value="Create Me!" />    
<%=Html.EndForm(); %>

What is the "correct" way to create a simple form with a button and textbox in ASP.NET MVC and allow me to submit the data in the form to the /Product/Create action?

How do I then access the form data from within that method? Some people seem to use a "FormCollection" and others just do a Request.Form method. Which way should I use?

Can someone enlighten me?

Have a look at Link. It's German text but the code should be understandable.

Have you looked at this:

It's from the horse's mouth, and is up-to-date with the final release.

The Form helpers are the recommended way because it allows you to provide a controller, action and other route data and the URL is auto-generated based on your routes (in Global.asax). The advantage is, if you decide to change your routes, you don't have to update every URL in your site.

The only reason I'd use an actual "<form>" tag was if I needed extra control over the markup that I couldn't get from Html.Form (I can't think of an example right now). Even if you choose to do that, you should use the "Url.Action" helper to get a URL from routing data. For example:

<form action="<%= Url.Action("Create") %>">

As for your second question, I'd suggest using the Model Binder. Check out ScottGu's Blog for some details on this.
