Default option label for DropDownList in ASP.NET MVC Preview 5

The ASP.NET MVC Preview 5 has provided the functionality to add a default option label for DropDownList control. For adding a default option label, provide the default label as the first argument of the DropDownList helper method. This will render the default option label element with its value attribute equal to an empty string, but with its inner text as the value that you provide.

<%=Html.DropDownList("--Select Customer--","Customer") %>

How do you get it so a blank option will show in the list? If I put a string.Empty there it doesn't add the blank option.

Ok when I first read this I was ready to complain :P

I thought this empty string would break my Binding in the Controller method for int types that are linked to the drop down.

Then I tested it real quick to get the error for complaining....

Dangit - it returns 0, just like I wanted.

Is this just some black magic in the background that is doing a cast from empty.string to 0 in the background ?

Add <asp:ListItem></asp:ListItem> like this <asp:DropDownList><asp:ListItem></asp:ListItem></asp:DropDownList>

This works whether you are using static values or dynamic values
