I am trying to pass a string variable inside asp.net MVC. I use breakpoints so I see that it does go to the correct method in the controller, but the variables posted are equal to null.
My markup:
#{
ViewBag.Title = "TestForm";
}
<h2>TestForm</h2>
#using (Html.BeginForm()) {
<input type="text" id="testinput" />
<input type="submit" value="TestForm" />
}
My controller:
public ActionResult TestForm()
{
return View();
}
[HttpPost]
public ActionResult TestForm(string testinput)
{
Response.Write("[" + testinput + "]");
return View();
}
I put the breakpoint inside the second TestForm method and testinput is null....
Am I missing something?
Note: I realize that most of the time I will be using the model to pass data around, but I would like to know that I can pass strings as well.
As part of the same question, how do I pass several variables? Would the method in my controller look like this:
[HttpPost]
public ActionResult TestForm(string var1, var2)
{
}
For me it looks like that you set the id not the name. I use MVC3 every day, so i dont reproduce your sample. (I am awake for 20 hours programming ;) but still motivated to help ) Please tell me if it dont work. But for me it looks like you have to set the "name" property ... not the id property. Try that ... i am waiting right now to help you if it does not work.
<input type="text" id="testinput" name="testinput" />
On a slightly separate note there is nothing wrong with passing variables like you are, but a more efficient way would be to pass around a strongly typed view model allowing you to take advantage of many aspects of MVC's goodness:
strongly-typed views
MVC Model Binding
Html Helpers
Create a new view model:
public class TestModel
{
public string TestInput { get; set; }
}
Your test controller:
[HttpGet]
public ActionResult TestForm()
{
return View();
}
[HttpPost]
public ActionResult TestForm(FormCollection collection)
{
var model = new TestModel();
TryUpdateModel(model, collection);
Response.Write("[" + model.TestInput + "]");
return View();
}
Your view:
#model <yourproject>.Models.TestModel
#{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>TestForm</title>
</head>
<body>
<div>
#using(Html.BeginForm())
{
<div class="editor-label">
#Html.LabelFor(m => m.TestInput)
</div>
<div class="editor-label">
#Html.TextBoxFor(m => m.TestInput)
</div>
<input type="submit" value="Test Form"/>
}
</div>
</body>
</html>

So I am trying to populate a model, which needs a userId. So right now, my ActionResult Index method just returns a view which prompts for the user to enter their userId. I need to grab this value and then create the viewmodel and then pass it in back to the view so that way I can do stuff like #Model.blah. I was wondering how I can do that, whether it'd be having two different action result methods, or in general how to populate models when the information you need must be queried first before constructing the viewmodel.
Here is my controller:
public ActionResult Index()
{
// Ask for UserID
return View("~/Views/FingerprintTool/Index.cshtml");
}
public ActionResult Index(int userId)
{
var response = _driver.ListFingerprints(userId);
var model = new FingerprintToolModel()
{
Fingerprints = response.Fingerprints
};
return View(model);
}
And here is my html:
model Models.Tools.FingerprintToolModel
<head>
<script type="text/javascript" src="~/Scripts/FingerprintTool.js"></script>
</head>
<body>
<h1>Fingerprint Tool</h1>
<form id="userIdForm" method="post">
Type in your UserId: <input name="userId" type="number" id="formUserId"/>
<input type="submit"/>
</form>
#if (Model != null)
{
<h1>SUCCESS</h1>
}
</body>
I also have a Javascript file that deals with the submit button be clicked and whatnot.
Here is the Js:
window.onload = function() {
$("#userIdForm")
.submit(function(e) {
e.preventDefault();
if ($("#formUserId").length == 0) {
alert("Invalid UserId");
} else {
listUserFingerprints();
}
});
}
function listUserFingerprints() {
// what to do here
}
Form:
First, update your form. You can use a simple HTML form, or the #Html.BeginForm() helper, like so:
#using Html.BeginForm()
{
#Html.AntiForgeryToken()
<label for="userId">Enter your User ID:</label>
<input type="number" name="userId" id="userId" />
<input type="submit" />
}
By default, your Html.BeginForm creates all the necessary elements and form action etc. If you prefer, you can still use standard HTML. Both do the same job.
Note the AntiForgeryToken. This is so useful when using POST form data (and even get, if you really must).
In your Controller, you can then check against this AntiForgeryToken, to protect against malicious posts or data being injected - see below.
Controller:
Create another method in your Controller, with the same name as your existing one; decorate it with the [HttpPost] attribute.
If you are using an AntiForgeryToken, you need to decorate the method with [ValidateAntiForgeryToken] also.
Like this:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index(int userId)
{
// MVC's DefaultModelBinder is smart enough to map your form
// post values to objects of the correct type, given the name in the form
// Get the data from your repository etc.
var model = GetUser(userId);
// Then return this model to the view:
return View(model);
}
Notice the parameter we are looking for in the method signature matches the name attribute of the input in your form.
MVC's DefaultModelBinder is able to make the connection between the two and map the value(s) of any parameters to form values.
You can also check if your model is null (for example, that userId doesn't exist) and then return an error to the page if so.
I like to use validation errors, but you can also use ViewBag or any other kind of method.
You can do a check and add an error, like this:
// Get the data from your repository etc.
var model = GetUser(userId);
if (model == null)
{
ModelState.AddModelError("", "The user ID you entered cannot be found. Please try again");
}
// Then return this model to the view:
return View(model);
This will add a "generic" model error to the view data, which you can then process in the view. More on that, below.
View:
In order to support your view displaying your model, you need to insert an #model statement at the top of your cshtml file.
Like so:
#model MyNameSpace.Models.User
This tells the view engine what Model type to expect from the Controller. In this case I have used User, but it would be whatever your class is called.
Be sure to use the fully-qualified namespace of your class in order to access it.
Then, in your HTML code, you can access the properties of your model using #Model.YourProperty.
Like this:
...
<div>#Model.Username</div>
<div>#Model.FullName</div>
<ul>
#foreach (var fingerPrint in Model.FingerPrints){
<li>#fingerPrint.WhateverProperty</li>
}
</ul>
...
As you can see, this loops through the FingerPrints (or whatever the property is called on your model object) and prints them out in a <ul>. This is to give you an idea of how to access the data from your model.
It is a good idea to create strongly-typed views like this - as this is the WHOLE idea of MVC in the first place :)
Don't forget to add an if check around the part of the page you're access the #Model data (otherwise you will get a NullReferenceException):
#if (Model != null){
<div id="modelDataInHere">
... // Display the data from your model, nice and pretty-like
</div>
}
Note the casing difference between the declaration and printing the values to the HTML output. I won't go into detail, but this is correct and necessary. Don't mix the two up.
Over to that "Validation Error" (AddModelError) we added in the Controller.
If you're using the Html.BeginForm() helper - like in the example - then you can add a Summary in the form, somewhere. When ModelState.AddModelError() is called in your controller, this populates the view data and this error can be displayed on the page.
Like so:
#using Html.BeginForm()
{
#Html.AntiForgeryToken()
// This puts any "generic" error messages at the top of the form
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
// Original form fields
<label for="userId">Enter your User ID:</label>
<input type="number" name="userId" id="userId" />
<input type="submit" />
}
No need for any Ajax or any JavaScript in here. You're simply using MVC for what it was designed in the first place.
You can use Ajax, however.
I would encourage you to read into it. There is also a similar helper: Ajax.BeginForm(), which renders the form as an Ajax one.
A bit of JS set up is required. And your controller action could return a PartialView, rather than a full-blown one.
Have a read up on using Ajax form posts here: http://eliot-jones.com/2014/09/mvc-ajax
The finished article
Time is marching on, and this post is getting longer.
But for the sake of clarity, your view and controller should look something like below. (I've stuck in a made-up class, so you can see the where the properties come from):
View
#model YourNameSpace.Models.User
... all your other code in here...
<div>
#using Html.BeginForm()
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<label for="userId">Enter your User ID:</label>
<input type="number" name="userId" id="userId" />
<input type="submit" />
}
</div>
#if (Model != null)
{
<!-- If there is a model present, display the data for it: -->
<div>
<div>#Model.Username</div>
<div>#Model.FullName</div>
<ul>
#foreach (var fingerPrint in Model.FingerPrints)
{
<li>#fingerPrint.WhateverProperty</li>
}
</ul>
</div>
}
Controller
public ActionResult Index()
{
// This is your standard "GET" request for "Index"
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index(int userId)
{
// MVC's DefaultModelBinder is smart enough to map your form
// post values to objects of the correct type, given the name in the form
// Get the data from your repository etc.
var model = GetUser(userId);
if (model == null)
{
ModelState.AddModelError("", "The user ID you entered cannot be found. Please try again");
}
// Then return this model to the view:
return View(model);
}
Sample model
public class User
{
public string Username { get; set; }
public string FullName { get; set; }
public List<FingerPrint> FingerPrints { get; set; }
}
Sincerely hope this helps you, and I wish you the best in your project.
Any questions, please feel free to ask :)
Seems like you need to work with json and AJAX method:
[HttpPost]
public ActionResult BasePage(int userId)
{
// user ID is binded to userId variable, based on the input name
var model = populate(userId);
// Remember to return the model to the view
return Json(model);
}
The Javascript for calling this would be:
function listUserFingerprints() {
$.post("/FingerprintTool/BasePage", {userId: $("#formUserId").val() }, function(model) {
console.log(model); // do whatever you want with model here
}
}
I am entirely new to asp.net mvc and this is my first sample project that I need to show one textbox in one view when the user entered a value in that textbox, I need to display that value in label in another view.
for that I have done like this ..
this is my controller class
public class TextBoxController : Controller
{
//
// GET: /TextBox/
public ActionResult Index()
{
return View();
}
}
and this is my model class
namespace MvcTestApplication.Models
{
public class TextboxModel
{
[Required]
[Display(Name= "Textbox1")]
public string EnteredValue { get; set; }
}
}
and this is my view
#model MvcTestApplication.Models.TextboxModel
#{
ViewBag.Title = "TextboxView";
}
<h2>TextboxView</h2>
#using (Html.BeginForm())
{
<div>
<fieldset>
<legend>Enter Textbox Value</legend>
<div class ="editor-label">
#Html.LabelFor(m => m.EnteredValue)
</div>
<div class="editor-field">
#Html.TextBoxFor(m=>m.EnteredValue)
</div>
<p>
<input type="submit" value="Submit Value" />
</p>
</fieldset>
</div>
}
I am not able to see any textbox and any button on page and I am getting error like
HTTP:404 : Resource Cannot be found
I am using visual studio 2012 and mvc4..
would any pls suggest any idea on this one ..
Many thanks..
RE-WRITTEN
In simple terms, to access a page on ASP.NET MVC, you should point the URL to its controller name. In this case, TextBox:
localhost:2234/TextBox/TextBox
Also, you forgot to add an ActionResult for this new view. When you're loading the page, it's going through the Index one, which is empty.
The final code should look like this:
Controller
public class TextBoxController : Controller
{
public ActionResult Index()
{
return View();
}
public ActionResult TextBox(MvcApplication1.Models.TextBoxModel model)
{
return View(model);
}
}
Model
public class TextBoxModel
{
[Required]
[Display(Name = "Textbox1")]
public string EnteredValue { get; set; }
}
Razor View (Index)
#{
ViewBag.Title = "Index";
}
<h2>Index</h2>
Razor View (TextBox)
#model MvcApplication1.Models.TextBoxModel
#{
ViewBag.Title = "TextBox";
}
<h2>TextBox</h2>
#using (Html.BeginForm())
{
<div>
<fieldset>
<legend>Enter Textbox Value</legend>
<div class ="editor-label">
#Html.LabelFor(m => m.EnteredValue)
</div>
<div class="editor-field">
#Html.TextBoxFor(m=>m.EnteredValue)
</div>
<p>
<input type="submit" value="Submit Value" />
</p>
</fieldset>
</div>
}
Make sure that you have registered the URL via route config.
Find more about asp.net routing here
UPDATE:
Make sure that file name of your view is Index.cshtml since your controller doesn't specify any return view names.
I have MVC application with a model like this :
public class ListOfMyModel
{
public List<MyModel> MyModels { get; set; }
public Guid MyID { get; set; }
}
public class MyModel
{
// Some code like :
public string MyString { get; set; }
}
And my post method in my controller is like this :
[HttpPost]
public ActionResult EditMe(ListOfModel myList)
{
try
{
if (ModelState.IsValid)
{
List<MyModel> myModels = myList.MyModels;
foreach (MyModel model in myModels)
// Some code
return RedirectToAction("Index");
}
catch
{
// Some code
return View(myList)
}
return View(myList);
}
And my view : ( I use Kendo UI ) ( P.S : Some code has been stripped away and replaced by comment code )
#model MyApplication.Web.Models.ListOfMyModel
#{
ViewBag.Title = MyTitle;
Layout = "~/Views/Shared/_MyLayout.cshtml";
}
<div class="span1"></div>
<div class="span8">

<div class="form-actions">
<button type="submit" class="btn btn-primary">Validate</button>
</div>
</fieldset>
</div>
</form>
</div>
</div>
</div>
But the problem is that when I push the submit button in my view, the method of my controller is called with all the data expected ( saw in Chrome ) but in this method, all of the model is null : The ID and the list... I don't known where the problem is ?
Thank you all for reading and trying to understand this, if you want more informations please tell me.
The MyId should be correctly received with your existing code.
The model binder can only match the value of inputs whose name have a matching property in the form. I.e. if you have an input like this <input name='bikes' ...> then your model should have a property Bikes so that the model binder can transfer the value from the input to the property. In your case you're creating input with dynamic names that doesn't have a matching property name. (NOTE: thei referes to the model you're using as the action parameter).
The farthest you can go is giving a series of input elements the same name, i.e. several elements like <input name='categories' ...> and receive it in an array parameter like string[] categories or a model which has a property like string[] Categories {get;set;}
In short, you have to redesign your model and view. If you used a List<string> instead of a List<MyModel>, and the view had a fixed name for the dropdow lists, like DropDownListFor(c => Model.MyModels, then the model binder would fill the MyModels property with the list of selected strings in each drop down list.
Hint: you can use a model for the View and receive a different model (or series of parameters) in the Action. In this way you can send more information to render the View, and receive a post with the essential data to process the user input.
See my answer to this question for alternatives. It explains something similar to this question.
I'm trying to display two partial views in my index view. In those partial views are data grids that I want to display data when something is searched in the search box I have set up. Both of these pages work when I do them separately, but I don't know how do use them as partial views.
My View looks like this:
#using (Html.BeginForm("Index", "Home", "POST"))
{
<div class="searchField">
<div class="searchbox">
Search: <input type="text" name="heatSearch" />
<input type="submit" value="Submit">
</div>
</div>
}
<div>
#Html.Partial("PartialChemAnalysis", (string)ViewBag.SearchKey)
</div>
#Html.Partial("PartialSlag", (string)ViewBag.SearchKey)
My Controller looks like this:
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(string heatSearch)
{
ViewBag.SearchKey = heatSearch;
return View();
}
public ActionResult PartialChemAnalysis(string heatSearch)
{
HomeModel C = new HomeModel();
IEnumerable<HomeModel> model = C.ChemList;
C.ChemistryDataPull(heatSearch);
return PartialView(C.ChemList);
}
public ActionResult PartialSlagView(string heatSearch)
{
PartialSlagViewModel D = new PartialSlagViewModel();
IEnumerable<PartialSlagViewModel> model = D.SlagList;
D.SlagViewDataPull(heatSearch);
return PartialView(D.SlagList);
}
Ideally what's in that search box would be passed to both views and the grids would form based on that. I'm not sure what I'm doing wrong so any help is appreciated.
I would start with this:
#{
//create your first model
HomeModel CModel = new HomeModel();
CModel.ChemistryDataPull(Model.SearchValue);
//create your other model
PartialSlagViewModel DModel = new PartialSlagViewModel();
DModel.SlagViewDataPull(Model.SearchValue);
}
#Html.Partial("PartialAnalysis", CModel)
#Html.Partial("PartialSlag", DModel)
This is assuming you've already searched, processed a postback, and you've returned the SearchValue back to your view in your model. You could return it in ViewBag.SearchValue instead I suppose and replace Model.SearchValue with ViewBag.SearchValue, but your model would be a better place to store it.
If I were you, I post it to another method.
#using (Html.BeginForm("Index", "Home", "POST"))
{
<div class="searchField">
<div class="searchbox">
Search: <input type="text" name="Search" />
<input type="submit" value="Submit">
</div>
</div>
}
#Html.Partial("PartialAnalysis", (string)ViewBag.SearchKey)
#Html.Partial("PartialSlag", (string)ViewBag.SearchKey)
//In Home Controller
[HttpPost]
public ActionResult Index(string Search)
{
ViewBag.SearchKey = Search;
return View();
}
Partial views do not require a controller action. The presence of a controller action will actually make it into a view.
In your #Html.Partial call you want to pass a view model for the view to consume. This is where you'd want to put the data for your grid, searched by whatever keywords, sorted, prepped and ready to render.
This can either be an entirely different view model you've created that is dedicated to supporting your partial view, exposed as a property in the parent page's view model, or simply an IEnumerable property in the parent page's view model that has the data (I prefer the first approach btw; it's heavier code-wise but preserves encapsulation better).
To wrap it all up, your controller looks like:
public class HomeController : Controller
{
public ActionResult Index(string search)
{
return View(new IndexViewModel(search));
}
}
Your view model looks like:
public class IndexViewModel
{
private string _search;
public IndexViewModel(string search)
{
_search = search;
}
public AnalysisViewModel AnalysisViewModel
{
get
{
return new AnalysisViewModel(_search);
}
}
public SlagViewModel SlagViewModel
{
get
{
return new SlagViewModel(_search);
}
}
}
and your view for showing the partials looks like
#Html.Partial("PartialAnalysis", Model.AnalysisViewModel)
#Html.Partial("PartialSlag", Model.SlagViewModel)
I needed to change my partial view calls in my view to:
#if(ViewBag.SearchKey != null)
{
<div>
#Html.Action("PartialChemAnalysis", "Home", (string)ViewBag.SearchKey)
</div>
<div>
#Html.Action("PartialSlagView", "Home", (string)ViewBag.SearchKey)
</div>
}
This is my model:
public class IndexViewModel
{
public FilterConditions conditions { get; set }
public IEnumerable<SelectListItem> Countries { get; set }
}
public class FilterConditions
{
public string condition11 { get; set }
// ...
}
And I have an Index action method like so:
public ActionResult Index()
{
var model = new IndexViewModel();
// fill the model here with default values
return View(model);
}
The view renders a form with the filterconditions as input types.
Now I want the post back from that form be handled by this action method:
[HttpPost]
public ActionResult Index(FilterConditions model)
{
// do some magic with model and return another view here
}
and this actually works (I put a breakpoint in the method, and it gets called), but the properties of my model are always empty (default values), while they should contain the values which were posted by the form.
When I modify the action method like this:
[HttpPost]
public ActionResult Index(IndexViewModel model)
{
// do some magic with model.conditions and return another view here
}
It all works like it should, but this is not "right" (IMHO), as I don't need the ´Countries´ list on return, I only need the selected country (which is one of the conditions).
What is a nice (best practice) way to make this work without having to take the whole original viewmodel as an input parameter?
Btw, I'm using ASP.NET MVC 2 (I don't think it really matters, as I think it's the same problem in MVC 3, but I'm not entirely sure of that).
(I have been looking around the internet for "best practices" regarding dropdownlists and viewmodels within asp.net mvc, but the different recommendations I found didn't really line up with each other, and a lot is already outdated as well. I didn't find an "official" best practice around this. I hope I'm going in the right direction (having the list as part of my viewmodel), feel free to correct me on this matter if I'm not. Also feel free to point me to "endorsed best practices" about this if you know of any.)
Update:
I found out that I can use the [Bind] attribute with a Prefix of "filterconditions". And this indeed works for this view. But my original problem (I admit, it was not included in my question) is not solved.
It happens that this particular action method is also called from another view (it is an ajax call) where it doesn't have that prefix, in that case it doesn't work any more now. Any suggestions?
I've found the solution.
Apparently, when I use the same name for the parameter variable as the name of the type (the case doesn't have to match), like this:
[HttpPost]
public ActionResult Index(FilterConditions filterConditions)
{
// do some magic with model and return another view here
// now the filterConditions variable actually contains values!
}
Everything works like it should (the values of my filterConditions are not empty/null anymore). Apparently, the default modelbinder uses the name of the parameter as the potential prefix for the binding.
I'm glad I found out, but it would be nice if this is more clearly documented somewhere. It's not obvious at all.
Edit:
On request: this is the code in my view (aspx):
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MyProject.Models.IndexViewModel>" %>
<%-- ... more stuff here ... --%>
<% using (Html.BeginForm())
{%>
<%= Html.ValidationSummary(true)%>
<fieldset>
<div class="editor-label">
<%= Html.LabelFor(model => model.FilterConditions.Country)%>
</div>
<div class="editor-field">
<%= Html.DropDownListFor(model => model.FilterConditions.Country, Model.Countries)%>
<%= Html.ValidationMessageFor(model => model.FilterConditions.Country)%>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.FilterConditions.Make)%>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.FilterConditions.Make)%>
<%= Html.ValidationMessageFor(model => model.FilterConditions.Make)%>
</div>
<%-- ... more fields inserted here ... --%>
<p>
<input type="submit" value=" Search... " />
</p>
</fieldset>
<% } %>
Hi fretje: Now I can use your way to solve your problem, First I have two Models "IndexViewModel" & "Index", and the DropDownList(it's doesn't matter, just offer the DropDown items):
public class IndexViewModel : Index
{
//public int value { get; set; }
public List<System.Web.Mvc.SelectListItem> items { get; set; }
}
public class Index
{
public int value { get; set; }
}
class DropDownList
{
public List<System.Web.Mvc.SelectListItem> GetDropDownList()
{
List<System.Web.Mvc.SelectListItem> result = new List<System.Web.Mvc.SelectListItem>();
result.Add(new System.Web.Mvc.SelectListItem
{
Value = "1",
Text = "Apple"
});
result.Add(new System.Web.Mvc.SelectListItem
{
Value = "2",
Text = "Milk"
});
return result;
}
}
And two Controllers is Test() and Test(Models.Index), I pass the IndexViewModel and postback IndexModel:
public ActionResult Test()
{
var result =
new Models.IndexViewModel
{
value = 1,
items = new Models.DropDownList().GetDropDownList()
};
return View(result);
}
[HttpPost]
public ActionResult Test(Models.Index posatback)
{
return View();
}
The View of Test() is:
<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-field">
<%: Html.DropDownListFor(m=>m.value, Model.items )%>
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
<% } %>
that's work! thank you fretje, I learned one more tech. : )
Maybe you can try
[HttpPost]
public ActionResult Index([Bind(Exclude="Countries")]IndexViewModel model)
{
// do some magic with model.conditions and return another view here
}
Hi~
You don't need to combine the whole SelectListItem to ViewModel, actually your ViewModel just only have a field to store user's choise, integer or string, then use DropDownListFor like:
<%: Html.DropDownListFor(item.WeaponID, MyApplication.Models.DropDownList.GetDropDownList() )%>
please see my post in my blogspot, I use a very simple example to explain:

let me know if you have any problems : )
