I'm using Razor to generate a SelectList like this:

@Html.DropDownList("StatusImovel", new SelectList(ViewBag.ListaStatus, "IdStatus", "Descricao"), new { @hidden = "hidden", @multiple = "multiple", @form = "nulo" })

I need it to load already with some selected items, so I'm trying this:

@Html.DropDownList("StatusImovel", new SelectList(ViewBag.ListaStatus, "IdStatus", "Descricao", ViewBag.StatusSelecionados), new { @hidden = "hidden", @multiple = "multiple", @form = "nulo" })

Being ViewBag.StatusSelecionados is array int[] with IdStatus I want. but it is not working.

Do you have any way to do this?

You are using the wrong helper, if you want multiple values to be selected, you need to use MultiSelectList()

@Html.DropDownList("StatusImovel", new MultiSelectList(ViewBag.ListaStatus, "IdStatus", "Descricao", ViewBag.StatusSelecionados), new { @hidden = "hidden", @multiple = "multiple", @form = "nulo" })
