I have the following code which creates a dropdown list.  

When the user selects an item, I want to call a certain action in a controller and pass the new value as a parameter. 

I have the following code, but this does not work and I get "Invalid regular expression C" when I check with Firebug.

```
            @Html.DropDownList(
                "ctrlName", 
                items, 
                null,
                new { onchange = "document.location.href = /Controller/Action/this.options[this.selectedIndex].value;" })

```
