I have a radio button in a foreach loop within a form to be posted. I want the first one to be checked when they are listed. `checked = "checked"` below doesn't help. It only works if there is a single radio button. 

```
<form action="/logged/hotel" method="post" >
    @foreach (var item in ViewBag.companies)
    {
       <input type="radio" name="graph" value="@item.Value" checked="checked" /> @item.Text<br />
    }
    <input type="submit" value ="LOG IN" />
</form>

```
