I developing business application in ASP MVC 5. I was trying to use Remote attribute but its not working.
Metadata class - where i put attribute
[MetadataType(typeof(Departmanmetadata))]
public partial class DepartmanTable
{
}
public class Departmanmetadata
{
[Key]
[DisplayName("Deparman No")]
public int DepartmanID { get; set; }
[Required(ErrorMessage = "Bu alan boş bırakılamaz!")]
[StringLength(50, MinimumLength = 2, ErrorMessage = "Lütfen 2 ile 50 karakter arasında veri giriniz!")]
[DisplayName("Departman Adı")]
[Remote("IsNameAvaible", "Departman", ErrorMessage = "Sistemde zaten var!")]
public string DepartmanName { get; set; }
}
Controller
public JsonResult IsNameAvaible(string name)
{
return Json(!db.DepartmanTable.Any(a => a.DepartmanName == name), JsonRequestBehavior.AllowGet);
}

Create button doesn't working.
I think Scripts is the problem. Here the scripts.
<script src="~/scripts/jquery-1.10.2.min.js"></script>
<script src="~/scripts/jquery.validate.unobtrusive.min.js"></script>
<script src="~/scripts/jquery.validate.min.js"></script>
What might be the issue?
The property you apply the attribute to is named DepartmanName and generates the following html
<input type="text" name="DepartmanName" ..... />
which means you controller method must have a matching parameter. Change it to
public JsonResult IsNameAvaible(string departmanName)
{
....
}

I am trying to create a Bootstrap modal pop up "Ticket successfully created" once you submit a form which posts data through to IActionResult to add to database. However my modal is like transparent with just text and I'm also getting a runtime error of : Obj ref not set to an instance of object
I have a feeling that modal popup is causing the passing of data back to the controller to not work. What is the way around this?

You can use ViewBag for open bootstrap modal after successfully return from server to client
Client Side View
#if(ViewBag.SuccessfullyTicketCreated != null)
{
<script>
$('#myModal').modal('show'); // open model by use jQuery
</script>
}
Server side Controller
_db.SaveChanges();
ViewBag.SuccessfullyTicketCreated = true; // create ViewBag after savechange success
I hope help you simple way
Only use of ajax call can solve your problem without creating any further issues. if you are not using jQuery, you can also send ajax call using Javascript using fetch() method.

First object getting value, but the list getting null.
#Html.DisplayFor() will not post values. You need to use #Html.HiddenFor() along with #Html.DisplayFor(). Refer: Html.DisplayFor not posting values to controller in ASP.NET MVC 3
if you're not passing any type of data then make your data as a hidden field and after that you will received your data at your respective controller.
Thanks.

Controller Function which should be called:
public ActionResult createXML(myClass arg)
{
//Code here...
return View("~/Views/Excel/Excel.cshtml");
}
My Problem is that "arg" is passed as null to createXML. I can't figure out why. One has to say that I am normally a WPF/WinForms Programmer.
UPDATE
I updated my code a bit, to make it clearer maybe.
UPDATE 2
I found out a part of the problem. My Object has only one constructor, where i need some paramateres. This generates somehow an error. I created a constructor without any parameter and it works, but it somehow creates a new object when I start my form and does not use the object i passed on to the view.
change view like this
#using (Html.BeginForm("createXML", "Excel", FormMethod.Post))
and
add this above createxml
[HttpPost]
UPDATE
I tried your codes and worked. Here is codes
HomeController codes. You can place this methods in your ExcelController
public ActionResult Excel()
{
myClass arg = new myClass();
arg.p = 5;
return View(arg);
}
[HttpPost]
public ActionResult createXML(myClass arg)
{
int a = arg.p;
return View();
}
Home/Excel.cshtml codes
#model Identity.Controllers.myClass
#{
Layout = null;
}
#using (Html.BeginForm("createXML", "Home", FormMethod.Post))
{ #Html.ValidationSummary(true)
<div class="container-full" style="background-color:aliceblue">
<h3 class="= container">Einstellungen:</h3>
<div class="container">
#Html.TextBoxFor(x => x.p)
<input type="submit" value="Submit" />
</div>
</div>
}
You are using wrong overload.
You can use this overload. BeginForm(
this HtmlHelper htmlHelper,
string actionName,
string controllerName,
Object routeValues,
FormMethod method,
Object htmlAttributes)
#Html.BeginForm("createXML", "Excel", new { arg = Model },FormMethod.Post,null)
or remove the argument and use hidden field within the form:
#using(Html.BeginForm("createXML", "Excel",FormMethod.Post))
{
.....
#Html.Hidden("arg", Model)
}
I can add a create partial view within a modal bootstrap so that it can add value in the table with a edit view of the field value ?
My create partial view
#model MVCLayout.Models.Table2
<p>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<div class="form-group">
#Html.Label("Cargo: ", new { style = "width:160px" })
#Html.TextBoxFor(model => model.ID, new { style = "width:200px" })

Can I do this with a partial view or the best way to do this?
create a property of Table2 type in your Table1 Model like below :
public class Table1
{
public Table2 table2 {get; set;}
//other properties of Table1 Model
}
Now in your Edit View:
<div class="modal-body">
#{
Html.RenderPartial("CreateTable2", Model.table2);
}
</div>
Now in your Action of the Controller :
public ActionResult Edit(Table1 model)
{
var editPartialViewData = model.table2;
// Do whatever you want to do with this data
}
I have this model, Customer . When i get the information with an id, it works just fine.
Like ;
/Customer/Entity/5
#model ProgSpace.Models.Customer
#{
ViewBag.Title = Model.Name;
Layout = "~/Views/Shared/_MainLayout.cshtml";
}
#section bodypane
{
#using (Html.BeginForm("Entity", "Customer", FormMethod.Post, new { #enctype = "multipart/form-data" }))
{
#Html.AntiForgeryToken()
<div class="col-md-12">
<div class="col-md-1">
<label>Customer No:</label>
<h4># #(Model.ID) </h4>
</div>
<div class="clearfix"></div><br />
<div class="col-md-2">
<div class="col-md-12">
<div class="col-md-12 fileupload fileupload-exists" data-provides="fileupload">
<div class="fileupload-preview fileupload-exists thumbnail" style="width: 200px; height: 150px;">
<img src="#Model.Picture.Path" />
</div>
<div>
<span class="btn btn-default btn-file">
<span class="fileupload-new">Add Pic </span>
<span class="fileupload-exists">Change</span><input name="file" id="file" type="file">
</span>
Remove
</div>
</div>
</div>
</div>
<div class="col-md-10">
<div class="col-md-3">
<label>Name *</label>
#Html.TextBoxFor(model => model.Name, new { #class = "form-control"})
</div>
<div class="col-md-3">
<label>Company</label>
#Html.TextBoxFor(model => model.Contact.Company, new { #class = "form-control"})
</div>
<div class="col-md-3">
<label>Phone </label>
#Html.TextBoxFor(model => model.Contact.Phone, new { #class = "form-control" })
</div>
</div>
<div class="clearfix"><br /></div>
<p> </p>
<div class="col-md-12">
<div class="btn-group">
<button class="btn btn-danger btn-lg">Cancel</button>
<button type="submit" class="btn btn-success btn-lg">Send</button>
</div>
</div>
</div>
}
}
And in the controller i have these actions.
public ActionResult Entity(int id)
{
Customer cust= sis.Customers.Where(t => t.ID == id).FirstOrDefault();
return View(cust);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Entity(Customer cust, HttpPostedFileBase file)
{
if (ModelState.IsValid)
{
/* Do something */
}
else
{
}
return View(cust);
}
When the verb is GET , it's fine. But when i post this form and when the second action (HttpPost action) kicks in , view throws an error..
Object reference not set to an instance of an object
which marks the Model.ID is null in the view.
<div class="col-md-1">
<label>Customer No:</label>
<h4># #(Model.ID) </h4> ---> THIS HERE THROWS NULL EXCEPTION
</div>
I've tried to add a HiddenFor for the Model.ID like
#Html.HiddenFor(t => t.ID)
but it didn't change anything.
How do i get back to the same view with the same context again ?
