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?

Having just started with Rhino Mocks, I'm having a little trouble mocking a call and return value from this method while testing my Presenter code. What's the correct syntax in this instance?
want to use Web Services in a project. I have basic concept of web services but couldn't understand some of its fundamentals.
1. what is SOAP, Rest and JSON ?
2. WCF Services are SOAP based or Rest or JSON based ?
3. Are Ado.net data services different from WCF ?
4. Which Web Services are easy to consume on client side ?
there's an .aspx page that does absolutely nothing in the codebehind, but contains the markup for the page in the Design View. Then we have an .asmx web service that receives requests with JSON content-type. These are called by the JavaScript in the page. This web service returns .NET objects serialized to JSON in response to these JavaScript Ajax HTTP POSTs. I'd like to switch to MVC but am not sure to how switch this architecture. Basically what we're doing is two things:
1) Replying to GET /MyPage.aspx with HTML markup that represents the page
2) Replying to POST /MyPage.aspx/WebMethodName requests with .NET objects serialized to JSON.
It seems like MVC would be a good way to eliminate the need for a Page object (again, the codebehind isn't used--only the HTML markup in the .aspx file is) and an .asmx web service. No? What do I need to start changing to accomplish this switch? Is it straight-forward? Painful? Someone at work already has an MVC page running in the same directory as my Web Forms .aspx and .asmx web service, but I don't see anything in the directory about Routes, so I'm confused. He's got a Views, ViewModels, and Controllers subdirectories.
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 use JSon to return allot of results when building a website, but find myself writing a a lot of code like this:
[Code]....
and then simply call this function with whatever IEnumerable results i have my question is would i be on the right lines here, what would be the best possible way to do this as it makes no sense to be writing in MVC and OOP but to keep rewriting code to just FROM ?
[code]....
What's wrong?
Edit: And what if I need to return {Message:'',Type:1} ?
Edit2: The answer for the last one is: I can return a Dictionary<string, string>
I have Categoreis and Locations I would like return both in one method. How can make a use of both Categories.ToList() and Locations.ToList()? What type of object should I return?

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.
Why web services can't return an arraylist? Y it can return List<> only?
View 2 RepliesI 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.

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.
I have a list of items(surveys) displayed on my home page. When I click the edit button for a particular item I have a modal pop up with the items details to edit. When the user clicks Save I submit the form via ajax. Depending on whether ModelState.IsValid == true I want to update the modal with validation information or close the modal and update the list of items with the new information.
This is how I am submitting the form:
[Code]...
My Questions
The only thing I can think to do is return JSON from my controller with a flag indicating the state of the ModelState.IsValid and the corresponding partial that I should show.
1) How would I do this?
2) Is there a better way?
Update
I found this: [URL]
but it seems more likely that I am going about the whole thing incorrectly.
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);)
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>
</tr>
}

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.
View 3 RepliesIn ASP.Net MVC action methods can return json objects simply by returning something like so:

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.
After much head scratching as to why my returned Json string is breaking JSON.parse, I have realized that it is the returned dates that it doesn't like.

I'm having a very hard time wrapping my head around this problem (it might be the heat from the summer finally arriving).
Problem:
I want the user to press a button client side which performs javascript data preparing and at last send a JSON structure to (currently a asmx webservice on) the server. The JSON structure is several levels deep.
Server side I create a PDF file which I want to send back to the user.
Goal:
The user feeling is that she presses a button and expects a PDF to return to her - either in a new window or as a download (preferrable).
Tools:
The system consists of (client side) HTML, JavaScript and ExtJS and (server side) ASP.NET.
Normally I would use an ashx handler to return a file to the client, but can I send a JSON structure to the handler and still be able to parse it correctly server side?
I am searching for the pattern to use.
