I have two actions in a controller that are called via ajax:
[HttpPost]
public ActionResult Slider(HttpPostedFileBase file)
{
var imagem = System.Web.HttpContext.Current.Request.Files["SliderImage"];
string path = Global.GetAppSetting("CaminhoImagensSlider");
if(imagem != null && imagem.ContentLength > 0)
{
String caminho = Path.Combine(path, imagem.FileName);
db.ImagensSlider.AddObject(new ImagensSlider()
{
Caminho = caminho
});
db.SaveChanges();
Global.SalvarArquivo(caminho, imagem.InputStream);
}
SliderViewModel sliderViewModel = new SliderViewModel(caminhoImagensSlider);
return PartialView("_ImagensSliderPartial", sliderViewModel.Imagens);
}
[HttpPost]
public ActionResult DeletaImagensSlider(int[] imagens)
{
foreach(int id in imagens)
{
ImagensSlider imagemSlider = db.ImagensSlider.Where(i => i.IdImagem == id).Single();
db.ImagensSlider.DeleteObject(imagemSlider);
db.SaveChanges();
}
SliderViewModel sliderViewModel = new SliderViewModel(caminhoImagensSlider);
return PartialView("_ImagensSliderPartial", sliderViewModel.Imagens);
}
The first action works fine, but the second (DeletaImagensSlider) does not work. Checking the Chrome console I found that error:
The partial view '_ImagensSliderPartial' was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/Configuracoes/_ImagensSliderPartial.aspx
~/Views/Configuracoes/_ImagensSliderPartial.ascx
~/Views/Shared/_ImagensSliderPartial.aspx
~/Views/Shared/_ImagensSliderPartial.ascx
~/Views/Configuracoes/_ImagensSliderPartial.cshtml
~/Views/Configuracoes/_ImagensSliderPartial.vbhtml
~/Views/Shared/_ImagensSliderPartial.cshtml
~/Views/Shared/_ImagensSliderPartial.vbhtml
EDIT:
JS
$("#formSlides").on("submit", function (e) {
e.preventDefault();
var data = new FormData();
var files = $("#imagem").get(0).files;
if (files.length > 0) {
data.append("SliderImage", files[0]);
}
$.ajax(this.action,
{
type: 'POST',
data: $(this).serialize(),
contentType: false,
processData: false,
data: data,
success: function (result) {
$("#imagensContainer").html(result);
}
});
});
$(document).on('change', '[type=checkbox]', function (e) {
if (this.checked) {
imagensChecadas += 1;
imagens.push(this.id);
}
else {
imagensChecadas -= 1;
imagens.remove(this.id);
}
if (imagensChecadas > 0) {
$("#btnDeleteImages").show();
}
else {
$("#btnDeleteImages").hide();
}
});
$("#btnDeleteImages").on("click", function () {
if (confirm("Tem certeza que deseja deletar estas imagens?")) {
$.ajax("/Configuracoes/DeletaImagensSlider", {
type: 'POST',
data: JSON.stringify(imagens),
contentType: 'application/json',
success: function (result) {
$("#imagensContainer").html(result);
}
});
}
});
Why is this view found in one action but not in the other?
I solve the problem by puting the entire path: "~/Areas/Admin/Views/Shared/_ImagensSliderPartial.cshtml".
But I cant understand why it works in different ways in the two actions...

I want to put a condition if the user want to add a second appointment he receives an alert
function SaveEvent(data) {
$.ajax({
type: "POST",
url: '/home/SaveEvent',
data: data,
success: function (data) {
if (data.status) {
//Refresh the calender
FetchEventAndRenderCalendar();
$('#myModalSave').modal('hide');
}
},
error: function () {
alert('Failed');
}
})
}
})
this is my code in controller :
public JsonResult SaveEvent(Event e)
{
var status = false;
if (e.EventID > 0)
{
//Update the event
var v = db.Events.Where(a => a.EventID == e.EventID).FirstOrDefault();
if (v != null)
{
v.EventTitle = e.EventTitle;
v.StartDate = e.StartDate;
v.EndDate = e.EndDate;
v.EventDescription = e.EventDescription;
v.EventID = e.EventID;
v.ThemeColor = e.ThemeColor;
}
else
db.Events.Add(e);
db.SaveChanges();
status = true;
}
i want to make the user add one time his event and receive an alert i try but not work
I think i can help:
if(Session["appointment"] != "ok")<>
{
if (e.EventID > 0)
{
//Update the event
var v = db.Events.Where(a => a.EventID == e.EventID).FirstOrDefault();
if (v != null)
{
v.EventTitle = e.EventTitle;
v.StartDate = e.StartDate;
v.EndDate = e.EndDate;
v.EventDescription = e.EventDescription;
v.EventID = e.EventID;
v.ThemeColor = e.ThemeColor;
}
else
db.Events.Add(e);
db.SaveChanges();
Session["appointment"] = "ok";
return JSON(new{appointment="ok"});
}
}else
{
return JSON(new {appointment="no-good");
}
and controller:
function SaveEvent(data)
{
$.ajax({
type: "POST",
url: '/home/SaveEvent',
data: data,

if (data.appointment == "ok")
{
//Refresh the calender
FetchEventAndRenderCalendar();
$('#myModalSave').modal('hide');
}
else { your msg error here }
},
error: function() {
alert('Failed');
}

I'm trying to save data using ajax in MVC 5. When I'm posting form data without #Html.AntiForgeryToken(), it's working nicely. But it's showing me Object reference not set to an instance of an object error for using #Html.AntiForgeryToken(). Here is my ajax code:
$.ajax({
type: "POST",
url: "/Employees/Create",
data: data,
async: false,
success: function (result) {
if (result == 1) {
window.location.href = '/Employees';
}
else {
$('#error-span').html('Error in insert.');
}
},
error: function () {
alert('Failed');
}
});
Here is my controller method:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Address,JoinDate,DoB,Gender,BloodGroup,Email,LastName,FirstName,Mobile,UpdateDate,UpdatedBy,Status,EmployeeType,CreatedBy,CreateDate,DesignationId")] EmpDetail empDetail)
{
try
{
Regex rgx = new Regex("[^a-zA-Z0-9 - .]");
empDetail.FirstName = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(rgx.Replace(empDetail.FirstName, "").ToLower()).Trim();
empDetail.LastName = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(rgx.Replace(empDetail.LastName, "").ToLower()).Trim();
empDetail.Email = empDetail.Email.ToLower().Trim();
empDetail.UpdateDate = DateTime.Now;
empDetail.CreatedBy = 234;
empDetail.CreateDate = DateTime.Now;
empDetail.UpdatedBy = 234;
empDetail.Status = 1;
if (ModelState.IsValid)
{
db.EmpDetails.Add(empDetail);
db.SaveChanges();
return Json(1);
}
else
{
return Json(2);
}
}
catch (Exception e)
{
return Json(e.Message);
}
}
This is happening because the data is being sent via JSON instead of HTML Form data. You should try to pass the token in the headers. For example:
View:
<script>
#functions{
public string TokenHeaderValue()
{
string cookieToken, formToken;
AntiForgery.GetTokens(null, out cookieToken, out formToken);
return cookieToken + ":" + formToken;
}
}
$.ajax("api/values", {
type: "post",
contentType: "application/json",
data: { }, // JSON data goes here
dataType: "json",
headers: {
'RequestVerificationToken': '#TokenHeaderValue()'
}
});
</script>
Controller:
void ValidateRequestHeader(HttpRequestMessage request)
{
string cookieToken = "";
string formToken = "";
IEnumerable<string> tokenHeaders;
if (request.Headers.TryGetValues("RequestVerificationToken", out tokenHeaders))
{
string[] tokens = tokenHeaders.First().Split(':');
if (tokens.Length == 2)
{
cookieToken = tokens[0].Trim();
formToken = tokens[1].Trim();
}
}
AntiForgery.Validate(cookieToken, formToken);
}

I was using MVC3 with AJAX. I was using AJAX within another AJAX. For the first AJAX request, it properly sends to the controller with data. But after returning from the AJAX request, I again posting the same data to another action. But second time the data comes null when coming to the controller. Please help me to fix this issue.
Code
$(document).ready(function () {
$('.deleteitems').live('click', function (e) {

I have gotten TypeAhead to work properly with static data and am able to call my controller function properly and get data but it is either A: Not parsing the data properly or B: The TypeAhead is not set up correctly.
JavaScript :
<input type="text" id="itemSearch" data-provide="typeahead" value="#ViewBag.Item" name="itemSearch"/>
$('#itemSearch').typeahead({
source: function (query, process) {
parts = [];
map = {};
$.ajax({
url: '#Url.Action("MakePartsArray")',
dataType: "json",
type: "POST",
data: {query: query},
success: function (data) {
$.each(data, function (i, part) {
map[part.description] = part;
parts.push(part.description);
});
typeahead.process(parts);
}
});
},
updater: function (item) {
selectedPart = map[item].itemNumber;
return item;
},
matcher: function (item) {
if (item.toLowerCase().indexOf(this.query.trim().toLowerCase()) != -1) {
return true;
}
},
sorter: function (items) {
return items.sort();
},
highlighter: function (item) {
var regex = new RegExp('(' + this.query + ')', 'gi');
return item.replace(regex, "<strong>$1</strong>");
}
});
Controller :
public ActionResult MakePartsArray(string query)
{
var possibleItem = query.ToLower();
var allItems = Db.PartInventorys.Where(l => l.ItemNumber.Contains(possibleItem)).Select(x => new { itemNumber = x.ItemNumber, description = x.Description });
return new JsonResult
{
ContentType = "text/plain",
Data = new { query, total = allItems.Count(), suggestions = allItems.Select(p => p.itemNumber).ToArray(), matches = allItems, },
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
}
In my controller I see the data being retrieved correctly and it appears to parse properly but nothing is showing up for my TypeAhead.
Any idea on how to verify exactly where the breakdown is occurring or does anyone see direct fault in my code?
Problem was in the ajax call-
$.ajax({
url: '#Url.Action("MakePartsArray")',
dataType: "json",
type: "POST",
data: {query: query},
success: function (data) {
$.each(data.matches, function (i, part) {
var composedInfo = part.description + ' (' + part.itemNumber + ')';
map[composedInfo] = part;
parts.push(composedInfo);
});
process(parts);
}
});
and in the controller on the return type
return new JsonResult
{
ContentType = "application/json",
Data = new { query, total = allItems.Count(), suggestions = allItems.Select(p => p.itemNumber).ToArray(), matches = allItems },
JsonRequestBehavior = JsonRequestBehavior.AllowGet
};
