how to insert fixed value into table in MVC - asp.net-mvc

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
