How to create an empty dropdown list with default value?

Question

I want to create an empty dropdown list that has just default value.I use the following code:

@Html.DropDownList("parent","--Select Parent--")

But in running time I see this error:

There is no ViewData item of type 'IEnumerable' that has the key 'parent'.

How can I solve it? Thanks.

You can build an empty DropDownList like this:

@Html.DropDownList("parent", Enumerable.Empty<SelectListItem>(), "--Select Parent--")
