Question

I have a dropdowlist in my view

<div class="editor-label">
                    @Html.LabelFor(model => model.SubProcessId, "SubProcess")
                </div>
                <div class="editor-field">
                    @Html.DropDownList("SubProcessId", ViewBag.SubProcessId as SelectList)
                    @Html.ValidationMessageFor(model => model.SubProcessId)
                </div>

That has this model

namespace CTTModel
{
    using System;
    using System.Collections.Generic;

    public partial class **SubProcess**
    {
        public SubProcess()
        {
            this.Risks = new HashSet<Risk>();
        }

        public int Id { get; set; }
        public string Name { get; set; }
        public int ProcessId { get; set; }
        public string Description { get; set; }

        public virtual **Process** Process { get; set; }
        public virtual ICollection<Risk> Risks { get; set; }
    }
}

which appears in the view via this controller

public ActionResult Create()
        {
            try
            {
                // Risk
                **ViewBag.SubProcessId    = new SelectList(_db.SubProcesses, "Id", "Name", "Process");**


                ViewBag.RiskSeverityId  = new SelectList(_db.RiskSeverities, "Id", "Name");
                ViewBag.RiskFrequencyId = new SelectList(_db.RiskFrequencies, "Id", "Name");
                ViewBag.RiskRatingId    = new SelectList(_db.RiskRatings, "Id", "Name");
                ViewBag.RiskType1Id     = new SelectList(_db.RiskType1, "Id", "Name");
                ViewBag.RiskType2Id     = new SelectList(_db.RiskType2, "Id", "Name");

                //Test
                ViewBag.RegionLevelId   = new SelectList(_db.RegionLevels, "Id", "Name");
            }
            catch (Exception ex)
            {
                throw;
            }

            return View();
        }

These are the suprocesses that show in the dropdownlist

Past due collection
Dealer audits
Credit Watch classification
Reconciliation
Control

Every sub process can have on process

Portfolio Management
Finance
Test Modeling

Now I was asked to show in the dropdownlist not the subprocess name, but instead

     "<process name> - <subprocess name>"   
Portfolio Management - Reconciliation, for example

And I have the faintest idea how to do that.
Any ideas??

var subProcessList = _db.SubProcesses
                        .Select(x => new 
                        { 
                            Id = x.Id,
                            Name = string.Format("{0} - {1}", x.Process.Name, x.Name) 
                        })
                        .ToList();

ViewBag.SubProcessId = new SelectList(subProcessList, "Id", "Name");
