ViewBag null control in DropDownListFor

Question

@Html.DropDownListFor(model => model.TransferAvailibilities.First().CancellationID, 
(ViewBag.CancellationSchema == null ? null : 
(IEnumerable<SelectListItem>)ViewBag.CancellationSchema), new { @class = "field large" })

And error:

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

I know that but i will bind data with ajax when i need. And my lambda not work or something for DropDownListFor...

Create SelectList from your ViewBag.CancellationSchema like this:

@Html.DropDownListFor(x => x.intClient, new SelectList(Model.Clients, "ClientId", "ClientName"), string.Empty);

My think that is not wrong syntax or something. I can see now a life cycle problem only. I solve my problem with another way. Render is firing before than lambda expressions... – Can Ürek Sep 28 '12 at 22:07
