Answer 1

You need to bind your dropdownlist to property WorkZoneID

@Html.DropDownListFor(m => m.WorkZoneID, Model.Workzones)

and if your wanting to preselect an option, you need to set the value in the controller before you pass the model to the view. And since your model contains a property for the SelectList , then use it (don't use ViewBag )

Company model = new Company
{
    WorkZoneID = 1 // set to a value that matches one of your options
    Workzones = cmpRep.GetWorkzoneDrop();
};
return View(model);

and when you submit to

[HttpPost]
public ActionResult Edit(Company model)

the value of model.WorkZoneID will contain the value of the selected option.
