通过ViewBag DropDownListFor [英] DropDownListFor via ViewBag

问题描述

这是一个后续本。

我的控制器

using (ISession session = NHIbernateSession.OpenSession())
{
    var index = session.Query<Transport>().ToList();
    List<SelectListItem> items = new List<SelectListItem>();
    foreach (var car in index)
    {
        items.Add(new SelectListItem() 
          { Text = car.Modelis.model_name, Value = car.Modelis.Id.ToString() }); 
    }
    ViewBag.Modeliai = new SelectList(items, "Id", "model_name");
    return View(items);
}

查看是这样的：

@Html.DropDownListFor(model => model.Modelis.model_name, ViewBag.Modeliai)

和什么是错的景观code。我如何把ViewBag值下拉列表？

And something is wrong with View code. How do I put the ViewBag value to the drop-down-list?

推荐答案

我仍然不知道你真正想要的选择，但下面应该工作：

I am still not sure WHAT you actually want to select, but following should work:

using (ISession session = NHIbernateSession.OpenSession())
{
    var index = session.Query<Transport>().ToList();
    List<SelectListItem> items = new List<SelectListItem>();
    foreach (var car in index)
    {
        items.Add(new SelectListItem() 
          { Text = car.Modelis.model_name, Value = car.Modelis.Id.ToString() }); 
    }
    ViewBag.Modeliai = items;
    return View(index);
}

和

foreach (var transport in Model)
{
    @Html.DropDownListFor(model => transport.Modelis.model_name, ViewBag.Modeliai)
}
