Question

我正在尝试将来自网址的ID存储在textboxfor()中，但我没有获得结果。当我在文本框中输入“id”时，我获得了正确的结果。而是在textboxfor(model=> model.IDCantiere,new{@value="id"})中。它没有运行;请帮助我，我附上了代码片段：

Controller.cs

// GET: CantiereOres/Create
public ActionResult Create(int id)
{
    ViewBag.id =  id;
    //ViewBag.IdCantiere = new SelectList(db.Cantieres, "IdCantiere", "IdCantiere");
    ViewBag.IdPersona = new SelectList(db.CantierePersones, "IdPersona", "Persona");
    return View();
}

// POST: CantiereOres/Create
// Per proteggere da attacchi di overposting, abilitare le proprietà a cui eseguire il binding. 
// Per ulteriori dettagli, vedere https://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]

public ActionResult Create([Bind(Include = "IdOre,IdCantiere,IdPersona,Ore,datetime")] CantiereOre cantiereOre)
{
    if (ModelState.IsValid)
    {
        db.CantiereOres.Add(cantiereOre);
        db.SaveChanges();
        return RedirectToAction("details", "Cantieres", new { id = cantiereOre.IdCantiere });
    }

    ViewBag.IdCantiere = new SelectList(db.Cantieres, "IdCantiere", "IdCantiere", cantiereOre.IdCantiere);
    ViewBag.IdPersona = new SelectList(db.CantierePersones, "IdPersona", "Persona", cantiereOre.IdPersona);
    return View(cantiereOre);
}

如果你想让2441在这个文本框中吗？

@Html.TextBoxFor(model=>model.IdCantiere,  new {@value ="id", @class = "form-control" } )

然后在你的控制器中，而不是这个：

ViewBag.id =  id;

这样做：

Model.IdCantiere = id;

将文本框更改为：

@Html.TextBoxFor(model=>model.IdCantiere,  new { @class = "form-control" })

将（在您的屏幕截图中）2441放在您指定的文本框中。

编辑：所以你需要从你的控制器返回一个archeagroup.Models.CantiereOre的实例创建方法：

public ActionResult Create(int id)
{
   var model = new acheagroup.Models.CantiereOre();
   model.IdCantiere = id;
   model... //other assignments - use this instead of ViewBag

   return View(model);
}

有了这个，上面的代码将起作用，因为它将从模型中提供。

我怎么能通过textboxfor（）存储“id”（urlparameter.optional）
