I have a textbox and a submit button were people put in there enter a 5 number pin and then it is to be safed inside a cookie for 4 months but its not working im getting nothing out of it.. what could be wrong.. this is my first time trying cookies
Read View
public ActionResult Index()
{
//read cookie and send it to view model
var mycookie = Request.Cookies["mypreference"];
ViewData["prefvalue"] = mycookie.Value;
return View();
}
HttpPost
[HttpPost]
public ActionResult Index(FormCollection ss)
{
// create cookie
HttpCookie preference = new HttpCookie("mypreference");
preference.Value = ss["preffer"];
preference.Expires = DateTime.Now.AddDays(120d);
Response.Cookies.Add(preference);
return View();
}
The view
#using (Html.BeginForm("seotips", "home", FormMethod.Post))
{
#Html.TextBox("preffer")
<input type="submit" value="submit" />
}
#ViewData["prefvalue"]
you have to try this
public ActionResult Index()
{
HttpCookie coo = new HttpCookie("name");
coo["Country"] = "INDIA";
ViewData["prefvalue"] = coo["Country"];
return View();
}

I'm trying to get errors to show up after an ajax submit has returned an error. I'm not sure what I'm missing, but I can't get it to work. This question is basically the same thing - ModelState.AddModelError is not being displayed inside my view but I'm still not having any luck. My experience with Ajax and MVC (any version) is still a bit limited. Here is a very simple example, most of which I took from the previous link.
View: test.cshtml
#model TestProject.VisitLabResult
#Scripts.Render("~/Scripts/jquery.unobtrusive-ajax.min.js")
#Scripts.Render("~/Scripts/ckeditor/ckeditor.js")
#{
AjaxOptions ajaxOpts = new AjaxOptions
{
Url = Url.Action("test"),
HttpMethod = "Post",
LoadingElementId = "loading",
LoadingElementDuration = 500,
OnSuccess = "processData"
};
}
#Html.ValidationMessage("CustomError")
<div id="loading" class="load" style="display:none">
<p>Saving...</p>
</div>
<table>
#for (int item = 0; item < 10; item++)
{
<tr id = #item>
#using (Ajax.BeginForm(ajaxOpts))
{
#Html.ValidationSummary(true)
#Html.AntiForgeryToken()
<td>
<input type="submit" value="Create" />
</td>
<td id = #(item.ToString() + "td")>
</td>
}
</tr>
}
</table>
Controller: HomeController.cs
public ActionResult test()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult test(VisitLabResult vlr, int visitid = 28)
{
try
{
if (ModelState.IsValid)
{
if (Request.IsAjaxRequest())
{
throw new Exception("error");
}
else
return View(vlr);
}
else
return View(vlr);
}
catch (Exception ex)
{
ModelState.AddModelError("CustomError", "The Same test Type might have been already created, go back to the Visit page to see the available Lab Tests");
return View(vlr);
}
}
Model
public class VisitLabResult
{
public int visitid { get; set; }
}
If it is an Ajax request I throw an error and it's caught and an error is added to ModelState. That error never shows up on the page though. Am I approaching this the right way at all? Or do I need to take a different route? I appreciate any help.
Just to clarify the solution for other people hitting this question. The ajax helper fires OnSuccess vs OnFailure based on the returned HTTP Code per the AjaxOptions docs:
OnSuccess: This function is called if the response status is in the 200 range.
OnFailure: This function is called if the response status is not in the 200 range.
In other words, you have to manually specify that there was a failure when returning your ActionResult by changing the Response.StatusCode and then returning whatever values you're expecting in your OnFailure js method. You can drive that based on any business logic you want (i.e. catch Exception ex) or !ModelState.IsValid ...)
[HttpPost]
public ActionResult Search(Person model)
{
if (ModelState.IsValid) {
// if valid, return a HTML view inserted by AJAX helper
var results = PersonRepository.Get(model)
return PartialView("Resulsts", vm);
} else {
// if invalid, return a JSON object and handle with OnFailure method
Response.StatusCode = (int)HttpStatusCode.BadRequest;
return Json(new { errors = ModelState.Values.SelectMany(v => v.Errors) });
}
}

I have a simple model called JobStatus, and I am enabling edit functionality within the Index view with an Ajax Actionlink.
My problem is that if there is a model error when editing an item, I don't know how to bring the item back to the model.
My Index action in my controller:
public ActionResult Index()
{
return View(db.JobStatuses.OrderBy(x => x.JobStatusID).ToList());
}
Here is my Index view:
#model IEnumerable<Project.Models.JobStatus>
#foreach (var item in Model)
{
<div id='#string.Format("div_{0}", item.JobStatusID)'>
#item.JobStatusID
#item.Name
#item.Description
#Ajax.ActionLink("Edit", "Edit", new { id = item.JobStatusID }, new AjaxOptions() { HttpMethod = "GET", UpdateTargetId = string.Format("div_{0}", item.JobStatusID) })
</div>
}
And here is my edit GET request:
public ActionResult Edit(string id = null)
{
JobStatus jobstatus = db.JobStatuses.Find(id);
if (jobstatus == null)
{
return HttpNotFound();
}
return PartialView(jobstatus);
}
My edit.cshtml:
#model Project.Models.JobStatus
#using Microsoft.Ajax;
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.HiddenFor(model => model.JobStatusID)
#Html.TextBoxFor(model => model.Name, null, new { #class = "form-control" })
#Html.TextBoxFor(model => model.Description, null, new { #class = "form-control" })
<input type="submit" value="Save" />
}
And finally my edit POST method:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(JobStatus jobstatus, string action)
{
if (ModelState.IsValid)
{
db.Entry(jobstatus).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
// Not sure what to do here, how to I repopulate my index form?
return RedirectToAction("Index");
}
At the moment, on a modelstate failure the user is just redirected to the index page - what I'd like is to simply redisplay the index form, with the appropriate edit form enabled and populated, and any validation errors shown.
I've tried redirecting to my Edit action, but this just shows my form on a new page, without my index form (because currently my edit action is an ajax action)
Of course, please let me know if there is a better way to achieve this!
You can't do the RedirectToAction with Ajax Post.
Check out asp.net mvc ajax post - redirecttoaction not working
But you can load in the following way
[HttpPost]
[ValidateAntiForgeryToken]
public JsonResult Edit(JobStatus jobstatus, string action)
{
if (ModelState.IsValid)
{
db.Entry(jobstatus).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return Json(new{id=jobStatus, success=true})
}
Once you get the JSON result from server you can load the same using the id returned
Like
$.post('/jobs/edit',{data:$(form).serialize()},function(data){
if(data.success){
$.get('/jobs/index/'+data.id,{},function(data){
$('#container').html(data);
});
}
});
I have created one page using MVC3. I have filled all the details and when I click the submit button it's not doing inserting, just postback and all the details gets lost.
This is controller
[HttpGet]
public ActionResult MyAccountIndex()
{
return View();
}
[HttpPost]
public ActionResult MyAccountIndex(MyAccount myacc)
{
MyAccount ma = new MyAccount();
var objview = ma.GetCustInfo(myacc);
return View();
}
Change your form in View to:
<form action="MyAccountIndex" method="POST">
<input type="submit" />
</form>
I'm new to ASP.NET MVC. I'm currently using ASP.NET MVC 3. I'm trying to create a basic form with an image button that posts data back to the controller. My form looks like the following:
MyView.cshtml
#using (Html.BeginForm())
{
#Html.TextBox("queryTextBox", string.Empty, new { style = "width:150px;" })
<input type="image" alt="Search" src="/img/search.png" value="Search" name="ExecuteQuery" />
}
MyController.cs
public class MyController: Controller
{
public ActionResult Index()
{
ViewData["CurrentDate"] = DateTime.UtcNow;
return View();
}
[HttpPost]
public ActionResult ExecuteQuery()
{
if (ModelState.IsValid)
{
return View();
}
}
}
I have verified that I'm accessing my controller code. The way I've been able to do this is by successfully printing out the "CurrentDate" associated with the ViewData. However, when I click my image button, I was assuming that my break point in the ExecuteQuery method would fire. It does not. What am I doing wrong? How do I do a simple POST in MVC?
Your form is pointing to the wrong action.
Calling Html.BeginForm() creates a <form> that POSTs to the current action (Index).
You need to pass the action name to BeginForm.
Try this one
#using (Html.BeginForm("ExecuteQuery", "MyController", FormMethod.Post))
{
#Html.TextBox("queryTextBox", string.Empty, new { style = "width:150px;" })
<input type="submit" value="Search" />
}
In your controller
public class MyController: Controller
{
public ActionResult Index()
{
ViewData["CurrentDate"] = DateTime.UtcNow;
return View();
}
[HttpPost]
public ActionResult ExecuteQuery(string queryTextBox)
{
if (ModelState.IsValid)
{
// DO SOMETHING WITH queryTextBox
return View();
}
}
}
If the image submit button is very important for you, you can still change the button background image using CSS.
I've noticed that with jQuery Mobile, if an anchor tag's href is the same as the current URL, the page does not refresh, as it does normally. I'm using a Stepped Wizard through a series of pages, and the final page has a link to repeat the process; this works fine except in jQuery Mobile. I'm new to the Mobile framework, so I'm not sure what events are firing that I need to hook into. Any help would be appreciated.
Here's a glimpse of the controller/ view code:
Controller:
public ActionResult Index()
{
var model = new MyViewModel();
return View(model);
}
[HttpPost]
public ActionResult Index(MyViewModel model)
{
if (ModelState.IsValid)
{
switch (model.SubmitButton)
{
case Buttons.Review:
return Review(model);
case Buttons.Confirm:
return Confirm(model);
}
}
return View(model);
}
public ActionResult Review(MyViewModel model)
{
return View("Review", model);
}
public ActionResult Confirm(MyViewModel model)
{
if (ModelState.IsValid)
{
return View("Confirm", model);
}
return View("Index", model);
}
View:
<div>
#* display stuff *#
#Html.ActionLink("Do it again!", "Index", "MyController", new { area = "MyArea" }, new { data_role = "button" })
#* display more stuff *#
</div>
Hmm, the code you posted is not javascript and for sure not using JQM..... Is that your aspx code-behind?
Either way, you'll probably want to disable JQM's ajaxEnabled loading if you want to reload the whole page in the current browser window.
