Question

I have a drop down list in C# asp.net MVC3 razor engine. I need to load values to that dropdownlist from one of my tables in my database and some values are hard coded. So I need to get both kind of values into one dropdown list.

我可以分开做

我的看法是这样的:

@Html.DropDownListFor(model => model.MyTransaction.Status, new MultiSelectList(ViewBag.MyStatusId, "ID", "Name"))

我的模型创建 enums 创建 :

public enum Ntypes{
  halfday
  casual
}

我的主计长:

ViewBag.MyTransaction = db.LeaveTypes.ToList(); //get the table values to drop down

这样我就能分开硬编码的数值............

ViewBag.MyTansaction = (from NewLeaveTypes t in Enum.GetValues(typeof(Ntypes))
                                select new { ID = t, Name = t.ToString()).ToList();

But cant get both values into one dropdownlist. Plzzzz Help.

谢谢...

你可以将这2个名单混为一谈:

var nTypes = Enum
    .GetValues(typeof(Ntypes))
    .Select(t => new LeaveType { ID = t, Name = t.ToString())
    .ToList();
ViewBag.MyTransaction = db.LeaveTypes.ToList().Concat(nTypes);

然后在视图中:

@Html.DropDownListFor(
    model => model.MyTransaction.Status, 
    new SelectList(ViewBag.MyTransaction, "ID", "Name")
)
