MVC Bootstrap modal show validation result - asp.net-mvc

The problem:
I want to preform submit to form that is in modal and if validation faild to get the error message on the modal.
I'm using ajax validation (jQuery) as detailed here
Is there an elegant way to perform submit but on faild stay at modal to show error message?
My code:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(Cam c)
{
ViewBag.id = c.id;
using (Entities db = new Entities())
{
if (ModelState.IsValid)
{
db.camp.Add(c);
db.SaveChanges();
return RedirectToAction("Index", new { id = c.id });
}
}
return null;
}
Client:
#using (Html.BeginForm("Create", "Camp", FormMethod.Post, new { model =
Model }))
{
#Html.AntiForgeryToken()
<dt>
name:
</dt>
<dd>
#Html.TextBoxFor(model => model.name, new { #class = "form-control", #placeholder = "name", #id = "txtVenueID", style = "width:150px" })
</dd>
<dd>
#Html.ValidationMessageFor(model => model.name)
</dd>
<div class="modal-footer ">
<button type="button" class="btn btn-default" data-
dismiss="modal">Close</button>
<button type="submit" class="btn btn-primary">Save</button>
</div>
}
Model:
public partial class Cam
{
[Display(Name = "Name")]
[Required(ErrorMessage = "Require {0}")]
string name { get; set; }
}

Show the first form in modal via the action that build it but keep the model state errors - use This
For view to submit the form but keep result on the modal use the following:
<button type="submit" class="btn btn-primary">Save</button>
Javascript to get the submit result into the modal:
$(function () {
$.ajaxSetup({ cache: false });
$(':submit[data-modal]').on("click", function (e) {
e.preventDefault();
var linkObj = $(this).closest('form');
$.ajax({ // create an AJAX call...
data: linkObj.serialize(), // get the form data
type: linkObj.attr('method'), // GET or POST
url: linkObj.attr('action'), // the file to call
success: function(response) { // on success..
$('#Modal-Content').html(response); // update the DIV
}
});
});
});

I can't send a POST request from view to Controller in ASP.NET MVC

I have this form shown below:
#using (Html.BeginForm("NewArticle", "News",FormMethod.Post, new { name = "createForm", onsubmit = "return validateFormNewPost()" }))
{
#Html.TextBoxFor(p => p.adName, new { #class="form-control"})
#Html.DropDownListFor(p => p.tyepId, listType, "---Select Type---", new { #class = "form-control" })
#Html.TextBox("imgPath", "", new { #class = "form-control", id = "imgPath" })
#Html.TextAreaFor(p =>p.AdDescription,new { id = "editor" })
<button class="btn btn-reset btn-dark" type="reset">Reset</button>
<button class="btn-submit btn-primary btn" type="submit">Submit</button>
}
Controller:
[HttpGet]
public ActionResult NewArticle()
{
List<AdType> listType = typeModel.listForAdd();
SelectList s = new SelectList(listType, "id", "AdType1");
ViewBag.ListType = s;
return View();
}
[HttpPost]
public ActionResult NewArticle(Advertisement model,string imgPath)
{
// my code
return RedirectToAction("Category","News");
}
I'm trying to make a POST request by submit the form but it always send form data with a GET request. How can I fix it?
How are you sending the POST? Are you using AJAX or JavaScript from your MVC page or are you trying to hit the endpoint with an external application like Telerik Fiddler or Postman?
You can not make a POST request directly from the browser using the URL, my assumption is that may be what you are doing.
#using (Html.BeginForm("MethodNameinController", "Controller Name", FormMethod.Post))
{
//form fields with submit button
<input type="submit" value="Save" class="btn btn-default" id="create" />
}
And in Controller
[HttpPost]
public ActionResult MethodNameinController(Model model)
{
}

Ajax.BeginForm return PartialView code does not update

I am doing a login logout functionality using Ajax partial. For this I have a View which checks if the user is logged in or not and shows login or logout form accordingly.
On submit it does a ajax request and logs in or out the user. after doing so in controller I return same partial view.
So expected behavior is on return partial view must again check for login status and refresh the view accordingly, but instead same form is loaded.
Partial View:
#model Models.LoginModel
#if (Member.MemberIsLoggedOn())
{
using (Ajax.BeginForm("LoginForm", "Account", null, new AjaxOptions
{
HttpMethod = "POST",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "login-form-update",
},new {
#class="loginform form"
}))
{
<div class="col-md-12 padding-zero">
<div class="row flt-right">
Hello #Context.User.Identity.Name, <input type="submit" name="logout" class="btn btn-default" value="Log Out" />
</div>
</div>
}
}
else
{
using (Ajax.BeginForm("LoginForm", "Account", null, new AjaxOptions
{
HttpMethod = "POST",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "login-form-update",
}, new {
#class = "loginform form"
}))
{
<div class="col-md-12 padding-zero">
<div class="row flt-right">
<div class="form-group col-md-5">
#Html.TextBoxFor(x => Model.Username, new { #class = "form-control", #placeholder = "Username" })
</div>
<div class="form-group col-md-5">
#Html.TextBoxFor(x => Model.Password, new { #class = "form-control", #placeholder = "Password", #type = "Password" })
</div>
<div class="form-group col-md-2 flt-right">
<input type="submit" name="login" class="btn btn-default" value="Go" />
</div>
</div>
</div>
}
}
Controller:
public class AccountController : Controller
{
[HttpPost]
public ActionResult LoginForm(LoginModel model)
{
if (!ModelState.IsValid)
{
//Do nothing
}
// Login
if (Membership.ValidateUser(model.Username, model.Password))
{
FormsAuthentication.SetAuthCookie(model.Username, false);
return PartialView("Header/LoginForm", new Models.LoginModel());
}
else
{
ModelState.AddModelError("Username", "Username is not valid");
//do nothing
}
}
public ActionResult Logout()
{
FormsAuthentication.SignOut();
Session.Clear();
return PartialView("Header/LoginForm", new Models.LoginModel());
}
}
Now my problem is login/logout happens properly, but changes do not reflect unless page is refreshed, which is i want to avoid by Ajax.BeginForm(),
update
If i click two times the view changes, but this is not a good user experience.
I think this might be due to cache problem. You need to use output cache attribute to disable the cache for that action method .
You can use something like this.
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
Also clear your ModelState before the return .
ModelState.Clear();
return PartialView(model);

File upload not working as expected

I am trying to upload a file from my application and it is not working as expected. I am not getting any file into the action method.
I have my viewmodel as below
public class CallQueryViewModel
{
[Display(Name = "Attachment")]
public HttpPostedFileBase UploadFile { get; set; }
}
And my Razor form is as below
#{
var ajaxOptions = new AjaxOptions
{
HttpMethod = "POST",
OnBegin = "onCallAddBegin",
OnSuccess = "OnCallCreateSuccess",
OnFailure = "OnCallCreateFailure"
};
}
#using (Ajax.BeginForm("AddCall", "CallHandling", ajaxOptions, new { #id = "CallAddForm", enctype = "multipart/form-data" }))
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<div class="row">
<div class="col-md-6">
<div class="form-group">
#Html.LabelFor(model => model.UploadFile, new { #class = "col-md-2" })
#Html.TextBoxFor(model => model.UploadFile, new { #class = "col-md-10", type="file" })
</div>
</div>
</div>
<div id="Submit">
<input type="submit" value="Save" class="btn btn-success" />
</div>
}
And my controller action method is as below.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult AddCall(CallQueryViewModel model)
{
if ((model.UploadFile != null) && (model.UploadFile.ContentLength > 0))
{
// Upload file.
}
}
With the above code, when i am trying to upload the file, I am not receiving any file into the controller action method. The UploadFile is always coming as null.
Could someone suggest what I am missing ?

What am I doing wrong i this?
Found The Issue
I'm binding the partial view inside the bootstrap modal popup. When I upload from the popup, the upload returning null. Instead if I open the partial View directly in browser, then the file is present in the model. So there is no problem with file upload. The problem is with modal popup or something.
When Using Bootstrap model
When using partial View Directy
Check the difference found when using fiddler between the Bootstrap Modal Submit and Using the partial View Directly in the following image respectively
When posting from the modal popup, the content type is changed to application/x-www-form-urlencoded where as when using the partial view directly it is multipart/form-data
Found the root Issue.
$('form', dialog).submit(function () {
var $form = $(this);
var enctype = $form.attr('id');
$.ajax({
url: this.action,
type: this.method,
data: $(this).serialize(),
success: function (result) {
if (result.success) {
$('#myModal').modal('hide');
//Refresh
location.reload();
} else {
$('#myModalContent').html(result);
bindForm();
}
}
});
return false;
});
I'm using AJAX posting to submit the data from my form. When using $(this).serialize() the ajax success is being called but the file is not returning as the content type is different. How can I change this??
I think I have been able to identify your problem, Ajax does not support file serialization, you should use the following method in the script:
$('form', dialog).submit(function () {
var formData = new FormData($(this)[0]);
$.ajax({
url: this.action,
type: this.method,
contentType: this.enctype,
data: formData,
success: function (result) {
if (result.success) {
$('#myModal').modal('hide');
$('#replacetarget').load(result.url); // Load data from the server and place the returned HTML into the matched element
} else {
$('#myModalContent').html(result);
bindForm(dialog);
}
}
});
return false;
});
Ok, I think your current issue is related to the default settings for the jQuery.ajax method. By default, the content type for the jQuery.ajax() method is 'application/x-www-form-urlencoded; charset=UTF-8'. So, in a sample project, I modified your javascript function to specify the contentType as a paramter to the ajax method: contentType: this.enctype
I think there also may be a couple additional issues. The next issue that I noticed is that on submission, I was connecting to another actions, so I updated this line in the view:
#using (Html.BeginForm(null, null, FormMethod.Post, new { enctype = "multipart/form-data" }))
To this:
#using (Html.BeginForm("EditSlider", "<Your Controller Name>", FormMethod.Post, new { enctype = "multipart/form-data" }))
Lastly, when the ajax submitted, I was being redirected to the partial view. I believe this can be fixed by adding preventDefault to the ajax function:
$('form', dialog).submit(function (event) {
event.preventDefault();
var $form = $(this);
$.ajax({
url: this.action,
type: this.method,
contentType: this.enctype,
data: $(this).serialize(),
success: function (result) {
if (result.success) {
$('#myModal').modal('hide');
//Refresh
location.reload();
} else {
$('#myModalContent').html(result);
bindForm();
}
}
});
});
This is how I was able to get this example working in a sample project; please post an update if you have additional issues.
Usually, modal pop-ups are rendered at the end of the body. I'm pretty sure that bootstrap does the same thing. This, in turn, means that the content of the modal is moved to a new location and is taken out of your form element. I would recommend a reordering: move the form inside the modal window:
<div class="modal-body">
#using (Html.BeginForm(null, null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
#Html.AntiForgeryToken()
...
}
</div>
This will move the entire form (and not just the form elements) when the modal gets built.
Only the file uploaded return null? or the other textbox return null as well?
As #Andrei comments, usually the modals is moved to a new location and the form is not present or your partialview could be moved to make the modal works.
With jqueryUI I had a similar problem. I couldn't find in your question if you are using ajax to submit your data, you could use .ajax() to send your form and see if the image was upload
$.ajax({
url: "#Url.Action("Action", "Controller")",
type: "POST",
cache: false,
data: $("#YourFormID").serialize(),
success: function (result) {
//your success data
},
error: function (jqXHR, textStatus, errorThrown) {
//your error handler
},
});
return false;
If you don't want to use $.ajax(), you could try to use .appendTo() with jquery, wrap everything what it is inside your form in a div with an ID, then after you have all your data try to sepecify that you want to appendTo("#YourFormID") on a button click, or as you like. This work for me when I was using modal, hope it helps you with something. Good luck
If I understand you make the form in a partial View, and this partial is used in a modal popup, it's right.
1) make a model for used in the form with all elements for the form,
2) declare the model in the first line in the partial view
3) pass as parameter the model to the post function.
4) you use a Partial view, well is possible use this view in differents pages, you need specify the control to treatement the form. in code:
MODEL
public partial class SliderModel
{
[Required]
[StringLength(200)]
public string FileName { get; set; }
[StringLength(200)]
public string Title { get; set; }
[StringLength(1000)]
public string Description { get; set; }
public int? Order { get; set; }
[NotMapped]
public HttpPostedFileBase ImageFile { get; set; }
}
VIEW
#model YOURNAMESPACE.Models.SliderModel
<form method="post" class="form-horizontal" role="form" id="sendMail"
enctype="multipart/form-data" action="/CONTROLLERNAME/EditSlider">
#Html.AntiForgeryToken()
<div class="modal-body">
<div class="form-horizontal">
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
#Html.HiddenFor(model => model.Id)
<div class="form-group">
#Html.LabelFor(model => model.FileName, new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.TextBoxFor(model => model.FileName, new { #class = "form-control", #readonly = "readonly" })
#Html.ValidationMessageFor(model => model.FileName, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.ImageFile, new { #class = "control-label col-md-2" })
<div class="col-md-10">

</form>
CONTROLLER
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult EditSlider(SliderModel obj)
{

}
return PartialView("_EditSlider");
}
Try with following way this worked for me :
VIEW :
#using (Html.BeginForm("ComplaintAndSuggestion", "RegisterComplaints", FormMethod.Post, new { enctype = "multipart/form-data", id = "ajaxUploadForm" }))
{
:
:

<div class="row mb10">

<label for="file1">Upload Image 1</label>
<input type="file" name="images" id="file1" accept="image/*" />
</div>
<div class="col-sm-3 col-md-3">
<label for="file2">Upload Image 2</label>
<input type="file" name="images" id="file2" accept="image/*" />
</div>
<div class="col-sm-3 col-md-3">
<label for="file3">Upload Image 3</label>
<input type="file" name="images" id="file3" accept="image/*" />
</div>
<div class="col-sm-3 col-md-3">
<label for="file4">Upload Image 4</label>
<input type="file" name="images" id="file4" accept="image/*" />
</div>
</div>
<input type="submit" value="Create" />
}
Controller :
[HttpPost]
public ActionResult ComplaintAndSuggestion(Register register, IEnumerable<HttpPostedFileBase> images, IEnumerable<HttpPostedFileBase> videos)
{
foreach (var file in images)
{
if (file != null)
{
string filenameWithDateTime = AppendTimeStamp(file.FileName);
file.SaveAs(Server.MapPath(Path.Combine("~/Images/", filenameWithDateTime)));
fileUploadModel.FilePath = (Server.MapPath(Path.Combine("~/Images/", filenameWithDateTime)));
fileUploadModel.FileName = filenameWithDateTime;
fileUploadModel.FileType = "Image";
fileUploadModel.RegisterId = register.RegisterId;
mediaRepository.Add(fileUploadModel);
mediaRepository.Save();
}
}
}
Let me know.

How to display a model state error in case I am returning a partial view

I have the following action method for creating new network info:-
public ActionResult CreateVMNetwork(int vmid)
{
VMAssignIps vmips = new VMAssignIps()
{
TechnologyIP = new TechnologyIP() { TechnologyID = vmid},
IsTMSIPUnique = true,
IsTMSMACUnique = true
};
return PartialView("_CreateVMNetwork",vmips);
}
[HttpPost]
public ActionResult CreateVMNetwork(VMAssignIps vmip)
{
if (ModelState.IsValid)
{
try
{
repository.InsertOrUpdateVMIPs(vmip.TechnologyIP,User.Identity.Name);
repository.Save();
return PartialView("_networkrow",vmip);
}
catch (Exception ex)
{
ModelState.AddModelError(string.Empty, "Error occurred: " + ex.InnerException.Message);
}
}
return PartialView("_CreateVMNetwork", vmip);
}
And I have the following _CreateVMNetwork view:-
#model TMS.ViewModels.VMAssignIps
#using (Ajax.BeginForm("CreateVMNetwork", "VirtualMachine", new AjaxOptions
{
InsertionMode = InsertionMode.InsertAfter,
UpdateTargetId = "networktable",
LoadingElementId = "loadingimag",
HttpMethod= "POST"
}))
{
#Html.ValidationSummary(true)
#Html.HiddenFor(model=>model.TechnologyIP.TechnologyID)
#Html.Partial("_CreateOrEditVMNetwork", Model)
<input type="submit" value="Save" class="btn btn-primary"/>
}
and _CreateOrEditVMNetwork view:-
#model TMS.ViewModels.VMAssignIps
<div>
<span class="f">IP Address</span>
#Html.EditorFor(model => model.TechnologyIP.IPAddress)
#Html.ValidationMessageFor(model => model.TechnologyIP.IPAddress)
<input type="CheckBox" name="IsTMSIPUnique" value="true" #(Html.Raw(Model.IsTMSMACUnique ? "checked=\"checked\"" : "")) /> |
<span class="f"> MAC Address</span>
#Html.EditorFor(model => model.TechnologyIP.MACAddress)
#Html.ValidationMessageFor(model => model.TechnologyIP.MACAddress)
<input type="CheckBox" name="IsTMSMACUnique" value="true" #(Html.Raw(Model.IsTMSMACUnique ? "checked=\"checked\"" : "")) />
</div>
The problem I am facing is that in case there is a model state error when adding a new entity, a partial view will be displayed with the model state error as follow:-
So my question is , if there is a way to display the model state error with the partial view , without updating the table row “insert after” as I am doing currently?
Thanks
Given the age i'm guessing you have already found a solution to this,
But here is an example using InsertionMode.Replace, maybe it can help someone else.
Snipped from view
#using (Ajax.BeginForm("AddPerson", "Home", new AjaxOptions { HttpMethod = "POST", InsertionMode = InsertionMode.Replace, UpdateTargetId = "UpdateSection" }))
{
<div id="UpdateSection">
#Html.Partial("PersonModel", Model.Person)
</div>
<input type="submit" value="add" />
}
Snipped from the controller
if (!ModelState.IsValid)
{
return PartialView("AddPerson", Person);
}
just make sure the "jquery.unobtrusive-ajax.min.js" script is included (i'm not sure it is by default)
