JSON collection of objects isn't binding correctly - asp.net-mvc
I have a website where I am uploading an Excel document to the server through AJAX (Telerik control). When the document is uploaded it will return a JSON object collection of currency exchange rates. I then save that collection using the jQuery $.data() method. Then I call the grid to bind and pass my JSON object to my controller to bind the data to the grid. Everything seems to be working up to the point where the Action on the controller binds to the collection.
What am I missing, notice how the response from SelectImportedCurrencyRates returns '1/1/1' for dates, country code is 'null' and the exchange rate is '0'. When I Debug and check the bound object ICollection<CurrencyExchangeRate> currencyRatesImported, its bound with those values as '0', '1/1/1' and null
Controller
[HttpPost]
public ActionResult UploadRates(HttpPostedFileBase importRateDocument)
{
var rates = CurrencyExchangeRateRepository.ReadExcelRates(importRateDocument.InputStream, importRateDocument.FileName);
return Json(rates);
}
[HttpPost]
[GridAction]
public ActionResult SelectImportedCurrencyRates([Bind(Prefix = "CurrencyRatesImported")] ICollection<CurrencyExchangeRate> currencyRatesImported)
{
return View(currencyRatesImported != null ?
new GridModel(currencyRatesImported) :
new GridModel(new List<CurrencyExchangeRate>()));
}
Javascript
<script type="text/javascript">
function onUploadRatesSuccess(e) {
$('body').data('CurrencyRatesImported', e.response);
var grid = $('#CurrencyExchangeRates').data('tGrid');
grid.ajaxRequest();
}
function onCurrencyRatesImportedDataBinding(args) {
var currencyRatesImported = $('body').data('CurrencyRatesImported');
console.log(currencyRatesImported);
args.data = $.extend(args.data, { CurrencyRatesImported: currencyRatesImported });
args.data = args.data;
}
e.Response passed to onUploadRatesSuccess (result from ActionResult UploadRates()

Binding call to SelectImportedCurrencyRates
Response from SelectImportedCurrencyRates
CurrencyExchangeRate class
[Serializable()]
public class CurrencyExchangeRate
{
public string CountryCode
{
get;
set;
}
public System.DateTime Date
{
get;
set;
}
public double ExchangeRate
{
get;
set;
}
}
The problem was in the serialization of the collection I was sending up. It was passing an array up, instead of a serialized JSON object.
Here is what the serialization method should look like.
function serialize(prefix, data) {
var result = {},
dateRegex = /^\/Date\((.*?)\)\/$/;
for (var i = 0; i < data.length; i++) {
for (var field in data[i]) {
var value = data[i][field];
if (typeof value === "string") {
var date = dateRegex.exec(value);
if (date) {
value = $.telerik.formatString("{0:d}", new Date(parseInt(date[1])));
}
}
result[prefix + "[" + i + "]." + field] = value;
}
}
return result;
}
So then when I call onCurrencyRatesImportedDataBinding it will serialize my object of currency exchange rates and pass them up properly.
function onCurrencyRatesImportedDataBinding(args) {
var currencyRatesImported = $('body').data('CurrencyRatesImported');
console.log(currencyRatesImported);
args.data = $.extend(args.data, serialize("currencyExchangeRates", currencyRatesImported));
args.data = args.data;
}
I believe the issue is the format of the dates being sent across the wire.
Unfortunately the DefaultModelBinder in MVC doesn't know how to bind these dates.
You'll need to extend the DefaultModelBinder. See e.g.

Controller Returning Incorrect DateTime Format
When using the the Telerik DataSourceRequest within my controller any property with a DateTime data type is being returned as
{"Data":[{"EffectiveStart":"\/Date(1393660800000)\/"}
Instead of MM/dd/yy
The property on my Model is:
[DataType(DataType.DateTime)]
public DateTime EffectiveStart;
I have also included the js culture reference for Telerik in my file and initiated kendo.culture() with no luck. What am I missing?
As requested here is the controller:
public ActionResult Grid_Read([DataSourceRequest]DataSourceRequest request, int id)
{
try
{
using (var db = new MyEntities())
{
var query = from refA in db.Entity
join refB in db.Entity on refA.ID equals refB.ID
where refA.ID == id
select new ResultList
{
ResultId = refA.PayeeId,
EffectiveStart = refA.EffectiveStart,
};
List<ResultList> myvar = query.ToList();
DataSourceResult result = myvar.ToDataSourceResult(request);
return Json(result);
}
}
catch (Exception ex)
{
return Json(null);
}
}
One thing you could do is replace return Json(result); by return Content(JsonConvert.SerializeObject(result)); BTW, you will need Newtonsoft.Json to use JsonConvert.
Thanks for all the responses. The resolution on this was to include some client side JavaScript which formats the field at runtime:
function toDate(value)
var dateRegExp = /^\/Date\((.*?)\)\/$/;
var date = dateRegExp.exec(value);
return new Date(parseInt(date[1]));
}
Then add a to the Telerik Grid column:
.ClientTemplate("#= kendo.toString( toDate(DateCreated), \"MM/dd/yyyy\" ) #")
adding a new object to observable array in knockout mvc
I'm using knockout mapping to help map a serverside object into JSON. I have an object with numerous collections in it so I don't want to have to recreate and map each piece manually in javascript. So, I'm using knockout-mapping to do this for me.
I was having issues, so I decided to try it with a simple example, so here is what I have for an ASP.NET MVC application:
C# Model:
public class Vaccinations
{
public string Vaccination { get; set; }
public System.DateTime VaccinationDate { get; set; }
}
public class Dog
{
public string Name { get; set; }
public int Age { get; set; }
public Dog()
{
this.Vaccinations = new System.Collections.Generic.List<Vaccinations>();
}
public System.Collections.Generic.List<Vacinations> Vacinations { get; set; }
}
As you can see, each Dog has a list of vaccinations they may or may not have.
In my controller, I create and return a pre-populated Dog object:
public ActionResult Load()
{
Dog rambo = new Dog
{
Name = "Rambo",
Age = 5
};
rambo.Vacinations = new System.Collections.Generic.List<Vacinations> {
new Vacinations { Vacination = "Rabies", VacinationDate = DateTime.Now.AddYears(-1) },
new Vacinations { Vacination = "Mumps", VacinationDate = DateTime.Now.AddYears(-2) }
};
return Json(rambo, JsonRequestBehavior.AllowGet);
}
In my view (Index.cshtml), I have it set up to show the dog and a list of it's vaccinations. I want to allow the user to click on an Add Vaccination button to add a new line to the collection and allow them to enter the data.
Again, I'm using knockout.mapping to do the mapping for me. In the javascript section, this is what I have:
var ViewModel = function (data) {
var self = this;
ko.mapping.fromJS(data, {}, self);
self.isValid = ko.computed(function () {
return self.Name().length > 3;
});
// Operations
self.save = function () {
$.ajax({
url: "Dog/Save",
type: "post",
contentType: "application/json",
data: ko.mapping.toJSON(self),
success: function (response) {
alert(response.Status);
}
});
};
self.addVaccination = function () {
self.Vaccinations.push(new self.Vaccination()); // <--- This doesn't work and I know why, so how do I do this?
}
};
$(function () {
$.getJSON("Dog/Load", null, function (data) {
ko.applyBindings(new ViewModel(data));
});
});
My question revolves around the "addVaccination" function that I've added to the ViewModel object. How do I specify a new "Vaccination" object without having to "code" one in Javascript? That was the entire reason for me using knockout mapping so I don't have to do that. But, I don't see any other way around it.
Is there a way to access the base Vaccination object from the Vaccinations observable array so I can create a new one?
And then the final question is, how to I pass this back to my controller? I'm not sure if this will work or not.
You can't directly. But what you can do is define a Vaccination instance at the server side and return it as a the default instance.
So, you need to return the old data and the default instance.
public ActionResult Load()
{
...
var data = new {
defaultVacination = new Vacination(),
rambo = rambo,
};
return Json(data , JsonRequestBehavior.AllowGet);
}
And on the client side you receive the same data and the default instance.
var ViewModel = function (data) {
var self = this;
ko.mapping.fromJS(data.rambo, {}, self);
var defaultInstance = data.defaultVacination;
...
self.addVaccination = function () {
// clone the default instance.
self.Vaccinations.push(ko.utils.extend({}, defaultInstance));
}
I hope it helps.
How to retrieve column values using columnchooser in JQGrid?
Good day! I am working on a project right now and I am using JQGrid to show my data. As part of its functions, users can choose columns and make these columns as their default columns. I used 'columnChooser' to let my user select for their default columns. My problem now, how to retrieve those columns the user's selected? And how to set those columns as their default columns? Can someone help me with this problem. Thanks Jason
After the user changes the column layout, you can get the colModel from the grid, iterate through it and push the configuration in a array of json objects which will then be sent to the server. The following code does this:
function saveColumnConfiguration(grid, url) {
if (url.length > 0) {
var colArray = new Array();
var colModel = grid[0].p.colModel;
for (var i = 0; i < colModel.length; i++) {
if (colModel[i].name != "rn" && colModel[i].name != "cb") {
colArray.push({
Name: colModel[i].name,
Width: colModel[i].width,
Visible: !colModel[i].hidden
});
}
}
$.ajax({
url: url,
type: 'POST',
data: 'columnConfiguration=' + JSON.stringify(colArray)
});
}
}
The check for "rn" and "cb" means don't take the rownumber and checkbox columns.
UPDATE
You will need a class to represent the columns:
[Serializable]
public class JqGridColumn
{
public string Name { get; set; }
public int Width { get; set; }
public bool Visible { get; set; }
}
You also need custom model binder to deserialize the incoming list:
public class JqGridConfigurationModelBinder : IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var conf = bindingContext.ValueProvider.GetValue("columnConfiguration").AttemptedValue;
JavaScriptSerializer serializer = new JavaScriptSerializer();
var configuration = serializer.Deserialize<IEnumerable<JqGridColumn>>(conf);
return configuration;
}
}
Register the model binder in application start:
ModelBinders.Binders.Add(typeof(IEnumerable<JqGridColumn>), new JqGridConfigurationModelBinder());
The action in the controller that handles the list will be something like this:
public void SaveColumnConfiguration(IEnumerable<JqGridColumn> columnConfiguration)
{
// Save the list accordingly...
}
Note that the order of the columns is represented by their position in the list.
You can then easily read this configuration and render the grid.
UPDATE 2
The function in your case should be called like this
saveColumnConfiguration($("#freight_bill"), "/Controller/Action");
But not after the call for columnChooser. You can either make another button to save changes when the user chooses to do so or handle the done event from the column chooser like this:
$("#freight_bill").jqGrid('columnChooser', {
done: function (perm) {
if (perm) {
$("#freight_bill").jqGrid("remapColumns", perm, true, false);
}
saveColumnConfiguration($("#freight_bill"), "/Controller/Action");
}
});
MVC3 - posting byte array to a controller - Database RowVersion
I am working on an MVC3 application. My client side ViewModel contains a SQL Server RowVersion property, which is a byte[]. It is rendered as an Object array on the client side. When I attempt to post my view model to a controller, the RowVersion property is always null.
I am assuming that the Controller serializer (JsonValueProviderFactory) is ignoring the Object array property.
I have seen this blog, however this does not apply, as I am posting JSON and not the form markup:
http://thedatafarm.com/blog/data-access/round-tripping-a-timestamp-field-with-ef4-1-code-first-and-mvc-3/
My view renders my viewmodel like so:
<script type="text/javascript">
var viewModel = #Html.Raw( Json.Encode( this.Model ) );
</script>
I then post the viewModel to the controller like so:
var data = {
'contact': viewModel
};
$.ajax({
type: 'POST',
url: '/Contact/Save',
contentType: "application/json; charset=utf-8",
data: JSON.stringify(data),
dataType: 'json',
success: function (data) {
// Success
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.responseText);
}
});
Here is my action in the controller:
[HttpPost]
public JsonResult Save(Contact contact) {
return this.Json( this._contactService.Save( contact ) );
}
UPDATE: based on Darin's answer.
I was hoping for a cleaner solution, but since Darin provided the only answer, I will have to add a custom property that will serialize my byte[] "row_version" property to a Base64 string. And when the Base64 string is set to the new custom property, it converts the string back to a byte[]. Below is the custom "RowVersion" property that I added to my model:
public byte[] row_version {
get;
set;
}
public string RowVersion {
get {
if( this.row_version != null )
return Convert.ToBase64String( this.row_version );
return string.Empty;
}
set {
if( string.IsNullOrEmpty( value ) )
this.row_version = null;
else
this.row_version = Convert.FromBase64String( value );
}
}
My client side ViewModel contains a SQL Server RowVersion property, which is a byte[] Make it so that instead of a byte[] your view model contains a string property which is the base64 representation of this byte[]. Then you won't have any problems roundtripping it to the client and back to the server where you will be able to get the original byte[] from the Base64 string.
Json.NET automatically encodes byte arrays as Base64.
You can use JsonNetResult instead of JsonResult:
from https://gist.github.com/DavidDeSloovere/5689824:
using System;
using System.Web;
using System.Web.Mvc;
using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;
public class JsonNetResult : JsonResult
{
public override void ExecuteResult(ControllerContext context)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
var response = context.HttpContext.Response;
response.ContentType = !string.IsNullOrEmpty(this.ContentType) ? this.ContentType : "application/json";
if (this.ContentEncoding != null)
{
response.ContentEncoding = this.ContentEncoding;
}
if (this.Data == null)
{
return;
}
var jsonSerializerSettings = new JsonSerializerSettings();
jsonSerializerSettings.DateFormatHandling = DateFormatHandling.IsoDateFormat;
jsonSerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
var formatting = HttpContext.Current != null && HttpContext.Current.IsDebuggingEnabled ? Formatting.Indented : Formatting.None;
var serializedObject = JsonConvert.SerializeObject(Data, formatting, jsonSerializerSettings);
response.Write(serializedObject);
}
}
Usage:
[HttpPost]
public JsonResult Save(Contact contact) {
return new JsonNetResult { Data = _contactService.Save(contact) };
}
ASP.NET MVC: How to maintain TextBox State when your ViewModel is a Collection/List/IEnumerable
I am using ASP.NET MVC 2 Beta. I can create a wizard like workflow using Steven Sanderson's technique (in his book Pro ASP.NET MVC Framework) except using Session instead of hidden form fields to preserve the data across requests. I can go back and forth between pages and maintain the values in a TextBox without any issue when my model is not a collection. An example would be a simple Person model:
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
public string Email { get; set; }
}
But I am unable to get this to work when I pass around an IEnumerable. In my view I am trying to run through the Model and generate a TextBox for Name and Email for each Person in the list. I can generate the form fine and I can submit the form with my values and go to Step2. But when I click the Back button in Step2 it takes me back to Step1 with an empty form. None of the fields that I previously populated are there. There must be something I am missing. Can somebody help me out?
Here is my View:
<% using (Html.BeginForm()) { %>
<% int index = 0;
foreach (var person in Model) { %>
<fieldset>
<%= Html.Hidden("persons.index", index.ToString())%>
<div>Name: <%= Html.TextBox("persons[" + index.ToString() + "].Name")%></div>
<div>Email: <%= Html.TextBox("persons[" + index.ToString() + "].Email")%></div>
</fieldset>
<% index++;
} %>
<p><input type="submit" name="btnNext" value="Next >>" /></p>
<% } %>
And here is my controller:
public class PersonListController : Controller
{
public IEnumerable<Person> persons;
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
persons = (Session["persons"]
?? TempData["persons"]
?? new List<Person>()) as List<Person>;
// I've tried this with and without the prefix.
TryUpdateModel(persons, "persons");
}
protected override void OnResultExecuted(ResultExecutedContext filterContext)
{
Session["persons"] = persons;
if (filterContext.Result is RedirectToRouteResult)
TempData["persons"] = persons;
}
public ActionResult Step1(string btnBack, string btnNext)
{
if (btnNext != null)
return RedirectToAction("Step2");
// Setup some fake data
var personsList = new List<Person>
{
new Person { Name = "Jared", Email = "test#email.com", },
new Person { Name = "John", Email = "test2#email.com" }
};
// Populate the model with fake data the first time
// the action method is called only. This is to simulate
// pulling some data in from a DB.
if (persons == null || persons.Count() == 0)
persons = personsList;
return View(persons);
}
// Step2 is just a page that provides a back button to Step1
public ActionResult Step2(string btnBack, string btnNext)
{
if (btnBack != null)
return RedirectToAction("Step1");
return View(persons);
}
}
As far as I can tell, this is not supported in ASP.NET MVC 2 Beta, nor is it supported in ASP.NET MVC 2 RC. I dug through the MVC source code and it looks like Dictionaries are supported but not Models that are IEnumerable<> (or that contain nested IEnumerable objects) and it's inheritors like IList<>.
The issue is in the ViewDataDictionary class. Particularly, the GetPropertyValue method only provides a way to retrieve property values from dictionary properties (by calling GetIndexedPropertyValue) or simple properties by using the PropertyDescriptor.GetValue method to pull out the value.
To fix this, I created a GetCollectionPropertyValue method that handles Models that are collections (and even Models that contain nested collections). I am pasting the code here for reference. Note: I don't make any claims about elegance - in fact all the string parsing is pretty ugly, but it seems to be working. Here is the method:
// Can be used to pull out values from Models with collections and nested collections.
// E.g. Persons[0].Phones[3].AreaCode
private static ViewDataInfo GetCollectionPropertyValue(object indexableObject, string key)
{
Type enumerableType = TypeHelpers.ExtractGenericInterface(indexableObject.GetType(), typeof(IEnumerable<>));
if (enumerableType != null)
{
IList listOfModelElements = (IList)indexableObject;
int firstOpenBracketPosition = key.IndexOf('[');
int firstCloseBracketPosition = key.IndexOf(']');
string firstIndexString = key.Substring(firstOpenBracketPosition + 1, firstCloseBracketPosition - firstOpenBracketPosition - 1);
int firstIndex = 0;
bool canParse = int.TryParse(firstIndexString, out firstIndex);
object element = null;
// if the index was numeric we should be able to grab the element from the list
if (canParse)
element = listOfModelElements[firstIndex];
if (element != null)
{
int firstDotPosition = key.IndexOf('.');
int nextOpenBracketPosition = key.IndexOf('[', firstCloseBracketPosition);
PropertyDescriptor descriptor = TypeDescriptor.GetProperties(element).Find(key.Substring(firstDotPosition + 1), true);
// If the Model has nested collections, we need to keep digging recursively
if (nextOpenBracketPosition >= 0)
{
string nextObjectName = key.Substring(firstDotPosition+1, nextOpenBracketPosition-firstDotPosition-1);
string nextKey = key.Substring(firstDotPosition + 1);
PropertyInfo property = element.GetType().GetProperty(nextObjectName);
object nestedCollection = property.GetValue(element,null);
// Recursively pull out the nested value
return GetCollectionPropertyValue(nestedCollection, nextKey);
}
else
{
return new ViewDataInfo(() => descriptor.GetValue(element))
{
Container = indexableObject,
PropertyDescriptor = descriptor
};
}
}
}
return null;
}
And here is the modified GetPropertyValue method which calls the new method:
private static ViewDataInfo GetPropertyValue(object container, string propertyName) {
// This method handles one "segment" of a complex property expression
// First, we try to evaluate the property based on its indexer
ViewDataInfo value = GetIndexedPropertyValue(container, propertyName);
if (value != null) {
return value;
}
// If the indexer didn't return anything useful, continue...
// If the container is a ViewDataDictionary then treat its Model property
// as the container instead of the ViewDataDictionary itself.
ViewDataDictionary vdd = container as ViewDataDictionary;
if (vdd != null) {
container = vdd.Model;
}
// Second, we try to evaluate the property based on the assumption
// that it is a collection of some sort (e.g. IList<>, IEnumerable<>)
value = GetCollectionPropertyValue(container, propertyName);
if (value != null)
{
return value;
}
// If the container is null, we're out of options
if (container == null) {
return null;
}
// Third, we try to use PropertyDescriptors and treat the expression as a property name
PropertyDescriptor descriptor = TypeDescriptor.GetProperties(container).Find(propertyName, true);
if (descriptor == null) {
return null;
}
return new ViewDataInfo(() => descriptor.GetValue(container)) {
Container = container,
PropertyDescriptor = descriptor
};
}
Again, this is in the ViewDataDictionary.cs file in ASP.NET MVC 2 RC. Should I create a new issue to track this on the MVC codeplex site?
