AJAX :: Return Json Format From Page's Webmethod?

Jun 7, 2010

I have the following web method , no success on return a correct Json format.

[Code]....

GetAll() return list of type "Company" POCO classes.

The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.

Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."

How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?

WebMethod Return Values In JSON Format?

Jan 24, 2010

How to return values from Webmethod to the client in JSON format? There are two static int values that i want to return.Do I need to create new object with those 2 properties and return it?The GetStatus() method is called frequently and i don't like the idea of creating a special object each time just for json formatting...

[WebMethod]
public static int GetStatus()
{
int statusProcess,statusProcessTotal;
Status.Lock.EnterReadLock();
statusProcess=Status.Process; //Static field
statusProcessTotal=Status.ProcessTotal; //Static field
Status.Lock.ExitReadLock();
return ...
}
On client side I catch the return value in :
function OnSucceeded(result, userContext, methodName)
(PageMethods.GetStatus(OnSucceeded, OnFailed);)

Do SQL Queries Towards An SQL 2005 Express Server And Format The Return Value To JSON?

Feb 19, 2010

I'm completely new to both VB.NET and JSON, and I'm trying to figure out how to do SQL queries towards an SQL 2005 Express server and format the return value to JSON. I got the queries working using this (perhaps very newbie-like) code;

Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.UI
Imports System.Web.UI.WebControls
Partial Public Class SQLConnect
Inherits System.Web.UI.Page
'Defines SQL variables
Dim con As New SqlConnection
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
Dim ReadData As String
Dim i As Integer
Sub Click(ByVal s As Object, ByVal e As EventArgs)
'Define SQL address, database, username and password
con.ConnectionString = "Data Source=localhostSQLEXPRESS;Initial Catalog=tempdb;User ID=tesst;Password=test"
Try
'Initialize connection
con.Open()
'Specify SQL query
cmd = New SqlCommand("SELECT * FROM Member", con)
'Execute query, dump result array into variable
dr = cmd.ExecuteReader()
messageLabel.Text = "<br />Connection established<br />"
While (dr.Read)
i = 0
For i = 0 To dr.FieldCount - 1
'Dump query results into a variable
ReadData += dr.Item(i).ToString
Next
End While
'Print query results
messageLabel2.Text = ReadData
'Close connection
con.Close()
Catch ex As Exception
messageLabel.Text = "<br />Connection failed<br />"
End Try
End Sub
End Class

I have been looking at this, and I would love to see some code examples using this class or any other good method.

Getting JSON As Parameters In Webmethod From JQuery AJAX

Mar 13, 2012

I'm doing an jQuery AJAX POST call to a webmethod, which is working fine. If I'm passing data from the AJAX call, I normally get the data in the webmethod via webmethod parameters.

JavaScript Code:
$.ajax({"dataType": "json","contentType": "application/json","type": "POST","url": "Default.aspx/GetStuff","data": JSON.stringify({"a":"data1","b":2}),"success": function (msg) {    console.log(msg.d);}});
C# Code:
[WebMethod]public static object GetStuff(string a, int b){ }

Is there any way I can get the data as a Dictionary or some other object, instead of having to put in individual parameters to the GetStuff() web method for each data param? It's a POST request so nothing is in Request.QueryString, and Request.Params/Request.Form doesn't contain it either.

AJAX :: How To Format Text In C# Into Proper JSON Format

Nov 30, 2010

I'm using jquery autocomplete to call a .aspx page which returns some matching words.

The jQuery stuff relies on a JSON feed to work. Currently, in my C# I'm formatting the output as a string, which ouputs something like this:

{ query:'aa','aardvark','aardvarks']}

I was hoping that because the string is formatted in the JSON format, that would be good enough for the Javascript to process but it appears not.

how to format this text in C# into proper JSON format which JavaScript can deal with properly?

AJAX :: ASPX WebMethod Not Running The WebService Webmethod Returning The Page?

May 19, 2010

I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.

The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.

The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).

AJAX :: Toolkit:AutoCompleteExtender Return From Webmethod ?

May 7, 2010

i have used AjaxToolkit:AutoCompleteExtender, which calls a web method to get string array. Everything was working fine as its populating all the data.But the issue arise when web method is returning value in a string array like

arr[0]=1-12-100

arr[1]=1-10-100

the value im getting in the AutoCompleteExtender is the subtract of the result like

arr[0]=-111

arr[1]=-109

Why is it treating it like numeric and doing calculation when the return type is actual an string. i think its has to do sth with serialize and deserialize thing

JQuery :: Simple Return Value From WebMethod From Ajax Function

Sep 22, 2010

I have an Ajax function called from JQuery that goes to a webservice to return a value. I need a SIMPLE example on how I can do this. I've been going nuts with serializing and every other aspect of this topic. I need to return either an ArrayList with ONE string field or a DataTable of some kind. Either way, I'm populating it into a DropDownList. I'm willing to consider alternatives to this idea. (Background info - I get a value from a textbox and I need to run it through a DB to get an associated value or set of values). I'm being really general so that someone can show a simple example.

How To Get Ajax.Net PageMethod To Return JSON

Jan 12, 2010

I am using an AJAX.Net to call an ASP.Net PageMethod, which returns JSON serialized JSON data

{"d":"[{"Fromaddress":"testfrom1@test.com","Toaddress":"testto1@test.com"},{"Fromaddress":"testfrom2@test.com","Toaddress":"testto2@test.com"}]"}

The Response Header states the content type as

"Content-Type application/json; charset=utf-8"

However, the data is just available as a string, and does not seem to be available as JSON data from javascript. What do I need to do to work with the returned data as JSON from javascript?

MVC - JSON + HttpException - Return An Error Page

Jan 30, 2011

I'm trying to return an error page indicating that the user couldnt be found and therefore I throw a HttpException with status code 404, however for some reason it wont redirect to the error page? - Is there some sort of trick to handle error pages with JSON that I should be aware of? My current code:

public ActionResult Details(int id)
{
User userToGet = _session.Query(new GetUserById(id));
if(userToGet == null)
{
throw new HttpException(404, "User not found");
}
DetailsUserViewModel userToViewModel = AutoMapper.Mapper.Map<User, DetailsUserViewModel>(userToGet);
return Json(new
{
HTML = RenderPartialViewToString("Partials/Details", userToViewModel)
}, JsonRequestBehavior.AllowGet);
}

Update - Some more code:

// MyJs.js
function openBox(object) {
$("body").append("<div id='fadeBox'></div><div id='overlay' style='display:none;'></div>");
$("#fadeBox").html("<div style='position:absolute;top:0;right:0;margin-right:2px;margin-top:2px;'><a id='closeBox' href='#'>x</a></div>" + object["HTML"])
$("#fadeBox").fadeIn("slow");
$('#wrapper').attr('disabled', 'disabled');
$("#overlay").show();
jQuery.validator.unobtrusive.parse('#mybox') /* Enable client-side validation for partial view */
}
// List.cshtml
@model IEnumerable<MyDemon.ViewModels.ListUsersViewModel>
<table style="width:100%;">
<tr style="font-weight:bold;">
<td>UserId</td>
<td>UserName</td>
</tr>
@foreach (var user in Model)
{
<tr>
<td>@user.UserId</td>
<td>@user.UserName</td>
<td>@Ajax.ActionLink("Details", "details", "account", new { id = @user.UserId }, new AjaxOptions() { HttpMethod = "GET", OnSuccess = "openBox" })</td>

AJAX :: Use Return JSON Object From Web Service As A Declared Type?

Jan 3, 2010

I just hit the following issue: I am calling a web service that returns a serialized JSON object let's say: __type, FirstName, LastName (.net object Person with properties FirstName and LastName). __type's value is Test.Person

I have created a JS object using Type.registerNameSpace/registerClass called Demo.Person and it is registered on the page using the ScriptManager. Everything is working fine; I am able to get data from the server on the call back.

Is it possible to make the returned object from the web service be an instance of the declared JavaScript Demo.Person class? The idea would be to call a method like result.getFullName() on the client side without having to copy all the properties. This is just a simple scenario for more complex objects.

ASP WebMethod Returns JSON Wrapped In Quotes

Jun 8, 2010

I have an asp.net page with a WebMethod on it to pass JSON back to my javascript. Bellow is the web method:

[WebMethod]
public static string getData(Dictionary<string, string> d) {
string response = "{ "firstname": "John", "lastname": "Smith" }";
return response;
}

When this is returned to the client it is formatted as follows:

{ "d": "{ "firstname": "John", "lastname": "Smith" }" }

The problem is the double quotes wrapping everything under 'd'. Is there something I've missed in the web method or some other means of returning the data without the quotes? I don't really want to be stripping it out on the client everytime. Also I've seen other articles where this doesn't happen.
