Return Data From An Asmx Into JSON?
Jun 15, 2010
I want to return an array of javascript objects from my asp.net asmx file. ie.
variable = [
{
*value1*: 'value1',[code]....
I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable.
EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.

Just ramping up on JSON and JQuery and returning data to a ASP.NET web page from a web service using Ajax. The JQuery part is pretty straight-forward. However, when trying to return JSON formatted data instead of XML from a 2.0 web service, I'm stuck. The web service does have the System.Web.Script.Services.ScriptService attribute, so I can hit it via JavaScript; however, the web service always...always...returns data in XML format, no matter if I explicitly say I want JSON as the datatype in my JQuery code. So I don't know if this is an issue with the web service or the JQuery code. I posted this here, but realize that the category could be incorrect depending on where the issue is. Is there no way to return JSON data from a 2.0 web service? It's a production web service, so I can't change the code unfortunately.

Code:
public partial class _Default : System.Web.UI.Page
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static LoanSize[] GetLoanSize()
[Code] ....
This is how i read it in client size
Code:
function GetLoanSize() {
$.ajax({
type: "POST",
url: "Default.aspx/GetLoanSize",
data: "{}",
contentType: "application/json; charset=utf-8",
[Code] ....
My only problem is that it take too long to populate the dropdown. How to convert it into a JSON format so it will more faster populating the data.

function createSuccess(context) {
$get("result").innerHTML = context.get_data();
}
<% using (Ajax.BeginForm(new AjaxOptions {OnSuccess="createSuccess"}))
{%>
What does context holds in the createsuccess method? data return by controller? How do we return json data in the createsucess if so

I'd like to read data server-side from a web service that outputs in json format. I haven't found any good examples that don't use jquery and are server-side.
Specifically I'm looking at the "weight" field from this api:

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.

We have an exisiting Web Service which receives SOAP requests and returns the data accordingly. However, we have a new project which requires the same information but the Android SDK doesn't support SOAP so we need to use JSON. As JSON is just a data container format, I need to write a new module to replace the SOAP WSDL which receives a querystring from the Android app and then processes the data and returns it in a JSON packet. The problem is that having never used JSON I'm unsure as to how I return the data to the app in JSON format. Does anyone have any examples I can look at in VB.Net or C#?

I Need by service contract to return the xml/json result depending on the request type. function which will convert my result set (i am using linq to sql) so that i do not need to create the xml format for the result set by iterating through the table row many times.What is the suitable way to do that.
I need a kind of short cut method which will convert the table data to xml result.Had i been using asp.net mvc i would have been able to generate the xml data by overriding the the ExecuteResult method in the ActionResult and giving Conetnt-Type = "text/xml" as OP.But since i am using Wcf i don't have the controller context(as controller context is the parameter that needs to be passed to Execute Result).
My present code for converting the table data to the xml format is below.
public XDocument UsersLists(string authToken)
{
bool IsAuthenticated = Authenticate(authToken);
XDocument xDoc = new XDocument();
XElement root = new XElement("Users");
[Code]....
I need to eliminate this way of generating xml for each table records.

I am coding a classic .asmx web service. The method get data (as a string) from a server, then assign data to an object, then return that object. But I want to cache that object to a XML file for other request. It's because the data from server is not frequently change. Thus, after some minutes, I have to refresh the XML file. When I refresh XML file, I could write object to XML first, then return that object, but that approach maybe slowly.
How can I return the object for client first, then write this to XML file?

vs2010, .NET 4.0I have a webmethod which I want to return a data record (for example: name, surename, address, age, zip etc)I wonder how to accomplish this. I think the solution is about creating an object which contains all the records serialized. And then the webmethod returns this serialized object. I'm not 100% sure how to accomplish this, if some of you good provide me with some tips, tutorial or link to an article explaining it, that would be great

I have a controller that uploads a file. I would like to return a json result with bool success (if successfully uploaded otherwise false) and message (this could be error message that occured OR link to a file OR link to an image, depending on what was uploaded).What's the best way to approach thisI have this
public class UploadedFile
{
public bool Success { get; set; }
public string Message { get; set; }
}
then In my controller I would set Success to true/or/false and Message to <a href OR <img am i on the right track?How would i then parse this in the view so that when image it will show an image, if link show a link, if error simply alert error.

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?

I am new to MVC and am trying to join 2 SQL tables together and return them in a Json. One table is OutreachProgram. The other table is UserInfo. I want to return the rows from the OutreachProgram table that match on CenterID with the UserInfo table.
The code that exists now will pull all rows from the OutreachProgram table. I can't figure out how to add the UserInfo table to the query to make it work.
JsonGrid <OutreachProgram> grid =
new
JsonGrid<OutreachProgram>(db.OutreachProgram,
new
OutreachProgramFilter());
public Array GetItems(IQueryable<OutreachProgram>
source)
{ return (from r
in source.AsEnumerable()
select
new {
ID = r.OutreachProgramID, CenterID = r.CenterID, DateOutreachProvided = r.DateOutreachProvided.ToShortDateString(),
NameOfProvider = r.NameofProvider.ToString(),
}).ToArray();
}

Microsoft Ajax can expose webservices which respond with json or xml depending on configuration. I would like to mock these services using soap ui. Using the wsdl I can do this to mock the services in the case where xml is returned, however how can I mock the response when JSON is returned?
