Asp.net mvc dropdown list using ViewBag

Answer 1

I recommend you to define a ViewModel for your page with a OrganisationId property. Thus this value will be filled when selecting an entry of the organisations dropdown list.

@model BCO.Models.SelectOrganisationViewModel

@{
    ViewBag.Title = "OrganisationInfo";
}


    @Html.DropDownListFor(o => o.OrganisationId,
        new SelectList(ViewBag.Organisations, "Id", "Name"))

The SelectList itself expects

• the list to fill the DropDownList with
• the value ("Id")
• the text ("Name")

as parameters.
