Accessing List members in ViewData

问题

I'm passing a list in ViewData. How can I access a specific member, for examples the first item?

I want to specify the default value of a dropdownlist.

This is my current Template:

@(Html.Kendo().DropDownListFor(m => m)
    .DataTextField("Text")
    .DataValueField("Id")
    .BindTo((System.Collections.IEnumerable)ViewData["units"])
)

And what I'm looking for is something like: ViewData["units"][0].Id
