Question

I want to insert a fixed date into table. How can I do this ?

    <div class="editor-label">
        Description :
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(model => model.Description, new { @class = "textboxes" })
        @Html.ValidationMessageFor(model => model.Description)
    </div>

    <div class="editor-label">
        Date :
    </div>
    <div class="editor-field">
        @Html.TextBoxFor(model => model.Date, new { @class = "textboxes" }) /// I wanna be here a fixed date .
        @Html.ValidationMessageFor(model => model.Date)
    </div>

My controller code is:

public ActionResult Index(tblOrder tblorder)
        {
            if (ModelState.IsValid)
            {
                db.tblOrders.AddObject(tblorder);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            ViewBag.fxBudjet = new SelectList(db.tblBudjets, "ID", "Budjet", tblorder.fxBudjet);
            ViewBag.fxServiceType = new SelectList(db.tblServiceTypes, "ID", "Service", tblorder.fxServiceType);
            ViewBag.fxStartTime = new SelectList(db.tblStartDates, "ID", "StartDate", tblorder.fxStartTime);
            return View(tblorder);
        }

Do I need to change my controller code?

Answer 1

@Html.DisplayTextFor(model => model.Date, new { @class = "textboxes" })

if the date is needed in a post you can do

@Html.DisplayTextFor(model => model.Date, new { @class = "textboxes" })
@Html.HiddenFor(model => model.Date)

or in the post method you can use TryUpdateModel and exclude the date field

Edit from your update i would set the value for the model in the controller e.g. say you had a class year that you wanted to prepopulate the year value

    public ActionResult Create()
    {
        return View(new Year() { Value = DateTime.Now.Year });
    }

again if you want it for the post you can use a hiddenfor or else regenerate it in the post

if this field is only required in the post method a better option might be to create a viewmodel without that field and then have some mapping logic in the post method

Edit 2: As with MVC music store you should really have 2 methods a get and a post. I will assume it is for a create.

[HttpGet]
public ActionResult Create()
{
    ViewBag.fxBudjet = new SelectList(db.tblBudjets, "ID", "Budjet");
    ViewBag.fxServiceType = new SelectList(db.tblServiceTypes, "ID", "Service");
    ViewBag.fxStartTime = new SelectList(db.tblStartDates, "ID", "StartDate");
    return View(new tblOrder() { Date = DateTime.Now });
}

[HttpPost]
public ActionResult Create(tblOrder tblorder)
{
    if (ModelState.IsValid)
    {
        db.tblOrders.AddObject(tblorder);
        db.SaveChanges();
        return RedirectToAction("Index");
    }

    ViewBag.fxBudjet = new SelectList(db.tblBudjets, "ID", "Budjet", tblorder.fxBudjet);
    ViewBag.fxServiceType = new SelectList(db.tblServiceTypes, "ID", "Service", tblorder.fxServiceType);
    ViewBag.fxStartTime = new SelectList(db.tblStartDates, "ID", "StartDate", tblorder.fxStartTime);
    return View(tblorder);
}

then in your view something like

@model tblOrder

@Html.BeginForm()
{
    @Html.DisplayTextFor(model => model.Date, new { @class = "textboxes" })
    @Html.HiddenFor(model => model.Date)
    ...other form stuff
    <input type="submit" value="Delete" />
}

Hopefully this should give you some idea of how to fix your code
