<p>How to dynamically bind data to <code>&lt;%Html.Dropdownlist....</code> in ASP.NET MVC?</p>

Just pass the correct IEnumerable as the typed model or ViewData. Try something like this (out of my head):
```
```
<%= Html.DropDownList(string.Empty, 
    "myDropDownList",  
    new SelectList((IEnumerable)ViewData["stuff"], 
        "DescriptionProperty", 
        "ValueProperty")) 
%>
```
```
With that drop down list helper in MVC, you do not really "bind" data to it in the way it is done in the old ASP.NET.
