extending @Html.DropDownList mvc3

In my continuing effort to build out my form validation controls, I've gotten to the dropdownlist control and ran into a snag when I tried to customize this one.

I've tried using the TagBuilder and a simple String in extension methods to extend this control but when I try to "bind" it 开发者_开发百科to a list on the back end, it's not actually binding any data to my dropdownlist. I'm sure I'm missing something (IEnumerable or the like) on my custom control but I have no idea what....any suggestions (code samples would be terrific) would be awesome.

thanks

You can go through the ASP.NET MVC source and get an idea as to how it is implemented.

Go through the License as well!!
