MVC :: Passing Json Collection Object From View To Action

Nov 1, 2010

I am trying to send json data from view to controller action. But the issue is the data is not populating in the action parameter List<Score>.

View Model:
public class Score
{
public int QuestionId { get; set; }
public int PrevAnswerId { get; set; }
public int CurrAnswerId { get; set; }
public string CurrAnswerName { get; set; }
}

Json Data look like:
[
{QuestionId:1, PrevAnswerId:3, CurrAnswerId:3, CurrAnswerName:'Known to Broker'},
{QuestionId:2, PrevAnswerId:7, CurrAnswerId:7, CurrAnswerName:'Completed'},
{QuestionId:3, PrevAnswerId:10, CurrAnswerId:10, CurrAnswerName:'Report'}
]

On window load, I will construct the Json object using "eval()" function and do some operation in the data before its save. On Save Click, I will call the action through the ajax call.

$.ajax({
url: url,
type: "GET",
dataType: 'json',
data: {score: ScoreJson},
contentType: "application/json; charset=utf-8",
success: function () {
alert("succes");
},
error: function () {
alert("error...");
} });

Action:
public ActionResult SaveScore(List<Score> score)
{
// do something...
}

But here score comming as collection of 3 elements with zero(for interger property)/null(for string property) values. When I checked in the request I found the data in "parama" property like.

"Score%5b0%5d%5bQuestionId%5d=1 &Score%5b0%5d%5bPrevAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerName%5d=Known+to+broker&
Score%5b1%5d%5bQuestionId%5d=2 &Score%5b1%5d%5bPrevAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerName%5d=Completed&
Score%5b2%5d%5bQuestionId%5d=3 &Score%5b2%5d%5bPrevAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerName%5d=Travelers+Report&".

But I am not sure why it is not getting populated in the score list. One full day I spent for this issue but till now I didnt find the solution for this issue.

Passing Data From Controller To View Using JSon Object

Mar 4, 2011

I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code?

<script language="javascript" type="text/javascript">
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
var selectedID = $(this).val();
if (selectedID != "New Vendor Id") {
//$.post('Url.Action("DropDownChange","Refunds")', function(result) {
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
});
}
});
});
This is the code in my controller;
public JsonResult DropDownChange(string dropdownValue)
// This action method gets called via an ajax request
{
if (dropdownValue != null && Request.IsAjaxRequest() == true)
{
paymentApplicationRefund =
cPaymentRepository.PayableEntity(dropdownValue);
paymentApplicationRefund.Address1.Trim();
paymentApplicationRefund.Address2.Trim();
paymentApplicationRefund.Name.Trim();
paymentApplicationRefund.City.Trim();
paymentApplicationRefund.Contact.Trim();
paymentApplicationRefund.State.Trim();
paymentApplicationRefund.Zip.Trim();
return Json(paymentApplicationRefund,"application/json");
}
else
{
return null;
}

Javascript - Passing JSON To Controller Action

Mar 7, 2011

I have the following javascript. Problem is if I enter one row in the table "ingredients" but I am getting 2 rows in the resulting pass to controller action after seralising into my C# object. But the second object is null? I checked the javascript and the variable "cnt" is 1 not 2. Why would that be?

[code]

$("#Save").click(function () {
var title = $("#recipetitle").val();
var category = $("#category").val();
var preptime = $("#prepTime").val();
var preptimeperiod = $("#lstPrepTime").val();
var cooktime = $("#cookTime").val();
var cooktimeperiod = $("#lstCookTime").val();
var rating = $("#rating").val();
var method = $("#method").val();
var jsontext = '{ "RecipeTitle": "' + title + '",';
jsontext += '"CategoryID":' + category + ',';
jsontext += '"PrepTime":' + preptime + ',';
jsontext += '"PrepTimePeriod":"' + preptimeperiod + '",';
jsontext += '"CookTime":' + cooktime + ',';
jsontext += '"CookTimePeriod":"' + cooktimeperiod + '",';
jsontext += '"Rating":' + rating + ',';
jsontext += '"Method":"' + method + '",';....................

Web Service - Passing A Base Object With List / Collection?

Apr 9, 2010

We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission.

The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n.

Jan 1 2009, ABC
May 1 2010, 123
Jun 30 2010, XXXXX

What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX

MVC :: Passing A Collection Of Objects To The View?

Apr 16, 2010

I'm trying to pass a list of items from a LINQ query to a View, but I'm having trouble figuring out how to resolve a type issue. Here's the error:

The model item passed into the dictionary is of type 'System.Data.Linq.DataQuery`1[Project.Models.Diagnostic]' but this dictionary requires a model item of type 'Project.Models.Diagnostic'.

The issue seems to originate with this code from my Controller:

[Code]....

I tried changing the IQueryable<Diagnostic> to var and got the same error. Also played around with something like:

[Code]....

But then VS2008 says that diagnostics could never be null, and that's may not the best (or even valid) way to do it.

DataSource Controls :: Passing Object To ObjectDataSource.SelectParameters Collection

Mar 30, 2010

I'm trying to use an ObjectDataSource's SelectMethod() to retrieve a result set from a sql server database to populate a data table with various stored procs that have any given number of parameters. My approach is to pass an object which contains the stored proc name and information about its parameters into the SelectMethod(). My issue is that I don't know how to actually set the default value. Here is the code I have so far:

ObjectDataSource1.DataObjectTypeName = "WebApplication1.Children";
ObjectDataSource1.TypeName = "WebApplication1.Children";
ObjectDataSource1.SelectMethod = "Select";

Parameter odsParameter = new Parameter() { Name = "storedProc", Type = TypeCode.Object };

// How do you set the default value to reference an object?

ObjectDataSource1.SelectParameters.Add(odsParameter);

namespace WebApplication1
{
public class Children
{
public DataTable Select(object storedProc)
{
// do stuff here and get db values.
}
}
}

The default value of a Parameter object is a string type. Does anyone know how to set the default value with an object or how I can pass an object into the SelectMethod?

Passing A JSON Object To A Function On Server Side?

Jun 4, 2010

I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.

So I create jSON object on client-side

var myJsonObject = {
"arg1": var1,
"arg2": var2
}

and pass it in to

WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);

When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]

So in following server-side function, the argument value is [object Object]

public void RaiseCallbackEvent(string jsonObj)

I was expecting a string representation of JSON object. How do I pass in a string representation?

How To Send A Collection And A Few Other Values In Json Form To A Webmethod?

Sep 28, 2010

Upon clicking a button I need to send a collection and a few other variables to server in Json form.For each value in the collection the server code (C# ) wil update those other variables in the DB.

For example there is a ‘classnumber’ collection with values (First, Second, Third, ….),other variables (‘teacher_name’ and ‘subjectname’).For each value in the ‘classnumber’ collection I need to update the ‘teacher_name’ by searching for the ‘subject_name’ in the DB.So I need to pass the ‘classnumber’ collection,’teacher_name’,’subject_name’ values to server in json form. At the moment instead of sending the ‘classnumber’ collection I am sending ‘teacher_name’,’subject_name’,’classnumber’ as variables for each value in the collection ,which requires multiple requests made to the server.

Instead of these individual requests I am wondering if there is a way to send all the data at once to server in json form?

MVC :: Unable To Redirect To Action When Posting With Json?

Nov 8, 2010

I originally have the question posted here, but I need as many eyes as possible on it.Essentially, I'm having issues redirecting to an action in mvc2 when working with JSON data. I post a stringified JSON object to an action and the action in turn redirects as needed. It worked previously when using form fields, but not when I'm posting JSON. To get posted JSON objects to properly bind to parameters objects in MVC, I'm taking advantage of the JsonValueProviderFactory class from MVC2Futures/MVC3Beta.Why is this occuring? The jQuery ajax call is telling the server "I'm giving you json, I expect html in return" and all actions pointed to via RedirectToAction calls are structured in a similar manner. I instead get stuck in a loop, continually hitting the originally requested action, with a prompt to reenter authorization information to boot! It seems lose authentication/authorization information in the process.The linked question on

C# - How To Return Json From Action Method With Array Property

Mar 14, 2011

I am trying to return some data as json from an action method.

I have an employee object that looks like this:

public class Employee
{
public int EmployeeID {get; set;}
public string FirstName {get; set;}
public string LastName {get; set;}
//Other irrelevant properties
}

Then I have a view model as follows

public Class EmployeeViewModel
{
public Employee Supervisor{get; set;}
public List<EmployeeViewModel> Employees
}

I need to return a json object that looks exactly like this:

{id: 1, name: John, children: [
{id: 1, name: Joe, children: []},
{id: 1, name: Rob, children: []}
]}

For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.

How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.
