I have a textbox that should accept datetime formats only. I am not sure how to convert this in MVC. I also want to know how to rearrange to a "yyyyMMdd" format, which is what needs to be passed. 

```
<%=Html.TextBox("effectiveDate") %> 

```

My controller has nothing :X

```
public ActionResult Index()
{
     return View();
}

```

I know I am missing something... what is it?

I am not worried about entering a bad date right now... I just want to get the conversion concept.
