I'm working on an MVC2 site that needs to update the values of a select list based on the value selected by a user in another list. This is the response I'm getting from my controller's JSON action:
[{"Selected":false,"Text":"Client1Group1","Value":null},{"Selected":false,"Text":"Client1Group2","Value":null}]
public class JsonBuilder
{
private StringBuilder json;
public JsonBuilder()
{
json = new StringBuilder();
}
public JsonBuilder AddObjectType(string className)
{
json.Append(""" + className + "": {");
return this;
}
public JsonBuilder Add(string key, string val)
{
json.AppendFormat(""{0}":"{1}",", key, val);
return this;
}
public JsonBuilder Add(string key, int val)
{
json.AppendFormat(""{0}":{1},", key, val);
return this;
}
public string Serialize()
{
return json.ToString().TrimEnd(new char[] { ',' }) + "}";
}
}
Here is the Web Method [WebMethod]
public static string GetPersonInfo(string pFirstName, string pLastName)
{
var json = new JsonBuilder().AddObjectType("Person");
json.Add("FirstName", "Psuedo" + pFirstName).Add("LastName", "Tally-" + pLastName);
json.Add("Address", "5035 Macleay Rd SE").Add("City", "Salem");
json.Add("State", "Oregon").Add("ZipCode", "97317").Add("Age", 99);
return json.Serialize();

Does anyone know how to convert backend data to a json response using .NET technologies? It'd be nice to have this and use jquery to call some information on the backend.

I have trouble with JSON response compression. I look to response headers after uploading website to production server (Windows 2008, IIS 7) and found uncompressed response. Turning on "Enabled static compression" and ""Enable dynamic compression" in IIS control panel does not effect. ASPX pages was responsed gzipped, but webservice response uncompressed.
I looked to google, but no answer found about this trouble. Also, I try this [URL] way (and adding to web.config this module) - but this source is excellent working at development machine with ASP.NET development server (and have seven times response size reduced) and totally ignored at IIS7.
How I can apply gzip compression to json responses from my webservice?
I have asp.net mvc application. i want to configure the object in jquery and want to pass it to the the action of controller . where as in my script i am using this for configure data for the ajax call:

var json = $.toJSON(peform);
is not working as expect. is it need to add any js file to reference ? or mistake in syntax?
I am trying to load the JSON data that I am getting from an aspx page into a drop down list that I have on another page but I am getting the following javascript error.
Microsoft JScript runtime error: 'SiteID' is null or not an object

$.getJSON('Test.aspx?DepotID=' + DepotID, function (sites) {
i have few textbox on the form and when the user submit i want to capture the data and insert into db

I have a problem with a AJAX call I do in a application. It's a MVC application (ASP.net c#) with a lot of javascript.
When I do a call from my javascript to a controller (through a ajax call) the call gets to the class and function, but the data isn't there. The data is send in JSON.
I found a few of the same problem but most of the time they used another name voor de parameter then it is in there json.
Here is the code
[Code]....
I am having problems making an AJAX call when the response is over 2MB. Anything with a response under 2MB works fine. When the response is over 2MB, my "success" method never gets called. My application is ASP.NET MVC2.
I am making the call using the jQuery AJAX call:
$.ajax({ type: "post", data: ajaxData, url: ajaxUrl, success: updateItems, cache: false });
In my controller, I am using the Json() action result method:
public ActionResult GetItems(....) { ...
return Json(packet); }
When I watch the call in Fiddler it comes back with a HTTP 500 response. I tried setting the maxJsonLength in the Web.config file as shown here, but that doesn't seem to make any difference. How to allow a response over 2MB?
I have an ASPX page that I am using to write JSON. It works great in Firefox and Chrome, but when I try and use it in IE 8 it gives me an "The XML page cannot be displayed" error instead of allowing jQuery to load the JSON being written by the response. Here is what my code looks like:
protected override void OnLoad(EventArgs e)
{
Response.Clear();
Response.ClearHeaders();
Response.ContentType = "application/json";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Write(string.Format("[ {{ "Foo": "{0}", "bar": "{1}" }} ]", "Foo Content", "Bar Content"));
Response.End();
}
I am using the code as below of this post:First i will an fill array variable with the correct values for the controller action.Using the code below i think it should be very straigtforward by just adding the following line to the javascript:
data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val();
The <%= Html.AntiForgeryToken() %> is at his right place and the action has a [ValidateAntiForgeryToken]
But my controller action keeps saying: "Invalid forgery token"
====================CODE=======================
data["fiscalyear"] = fiscalyear;
data["subgeography"] = $(list).pa n

This is probably something simple. The following JQuery call is executing and calling the controller. The controller is executing correctly. I used the sample data that's commented out to verify that the templates were working also. However, the success function is not executing in the browser. Any thoughts or other ways I can debug this?
<script type="text/javascript">$(document).ready( function(){ alert("Here"); @* var myData = [ {first: "Jane", last: "Doe"}, {first: "John", last: "Doe"} ]; *@ $.getJSON( "/User/Filter",function(myData){ $("#myDataTemplate").tmpl(myData).appendTo("#itemContainer"); } ); alert("there"); }
);</script>
//Controller
public ActionResult Filter() { var myData = this.repository.GetAllUsers(); //return Json(myData); return Json(myData, JsonRequestBehavior.AllowGet);}
i built contact form in aspx 3.5 and i'm using jquery to send it to web service (asmx).the web service need to return success or error code. the problem is that at the web method i get only single value and not array. I'm kind of new in ajax and i tried a lot of solutions but without any results.. please if you can only explain me the principle of what to do it also be good..this is the client side:
$(document).ready(function()
{
$("#submit").click(function(event)
{
[code].....
when i debug i see that the input parameter "name" contains only one string - i dont know how to get the full json string that i send to the service and contains all the form data - i want to desirialize it to string array or something like, and process it.
I have 2 classes that are used to mirror the data from an ajax call. One (Customer) contains a property which is name, and the other is an array of Products.
Public Class Customer
Private _Name as String
Private _Products as Product()
Public Property Name() As String

using jquery json
I have a simple webservice that I would like to upload a file to. The problem is that I need the response in json.
Form my experience in order to get a response in Json my request has to have a content-type of 'application/json'. But ofcourse this cannot be the case with a file upload since the content type will have to be 'multipart/form-data'.
In my Json i want to return a value showing whether successful and a filename.

I try to get parse JSON response for the following link:
https://graph.facebook.com/feed/?ids=135395949809348,149531474996&access_token=
The response is like that:
{
"135395949809348": {
"data": [
{
....Some data
}]
}
,
"325475509465": {
"data": [
{
....Some data......
}]
}
}
I use System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(string json) method.
But the objects key names always different , so I can't define the class that can be used for parsing this response.Is anyone has any experience in parsing multiple id's response from Facebook?
