OK, nearly 2 years later, you probably don't care anymore. Who knows: Maybe others (such as me ;-) do.

So here's the (extremely simple) solution:

In your Html.DropDownList(...) call, change

new { onchange = "this.form.submit()" }

to

new { onchange = "this.form.onsubmit()" }

Can you spot the difference? ;-)

The reason is that Ajax.BeginForm() creates a form with an onsubmit() handler to submit the form asynchronously. By calling submit(), you bypass this onsubmit() custom handler. Calling onsubmit() worked for me.
