MVC - Set selected value of SelectList inside ViewModel

How can I set the selectedvalue property of a SelectList after it was instantiated without a selectedvalue.

Controller

var _walkInnVM = new WalkInnVM
{        
    ProspectHandledEmpList = new SelectList(_db.Employees
        .AsEnumerable()
        .Where(e => e.Id == Int32.Parse(Session["LoggedUserId"].ToString()))
        .ToList(), "Id", "Name")       
};

HTML

@Html.DropDownListFor(m => m.ProspectHandledEmpID,
    Model.ProspectHandledEmpList, "", 
    new { @class = "form-control select2 ", @id = "ddlProspectHandled" })

You need to set the value of ProspectHandledEmpID in the model before you pass it to the view

var _walkInnVM = new WalkInnVM
{
    ProspectHandledEmpID = someValue, // add this
    ProspectHandledEmpList = new SelectList(_db.Employees.AsEnumerable()
      .Where(e => e.Id == Int32.Parse(Session["LoggedUserId"].ToString())), "Id", "Name")       
};

If db.Employees contains items with Id values from 1 to 10 and you set the value ProspectHandledEmpID = 3, then the 3rd option will be selected when the view is first generated.
