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.

I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?

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.

In ASP.Net MVC action methods can return json objects simply by returning something like so:
JSon([whatever])
How do I return a JSon representation of say List<String> with webforms either through a service or through a method in the code behind of an aspx page? This seems incredibly confusing compared to ASP.Net MVC.

I display the error message from serverside by passing it to the Scriptmanager AsyncPostBackErrorMessage.
But when I call it from the client like this
[Code]....
it adds some information about the exception type aswell. (Something like "Sys.WebForms.PageRequestManagerTimeoutException: The server timed out.")
Can I display the error without the information about the exception?

my controller, I'm generically deserializing Xml. The object being deserialized to could end up being any number of different types. This, of course, won't be known at compile time. I've created a number of partial views, each of which are strongly typed to a different object that is a possible outcome of the Xml deserializaton.My problem is that I'm struggling with a good way to return the right view. I could always switch on some property in the object, or use a Key/ViewName Dictionary mapping to get the right view name, but I was hoping for something a little more generic than that.Does anyone know of a way that I could implicitly say, "return the view that is typed off of the object I have."?

I have a webservice - called MyCompany.WebService1
I reference this using a web reference in my ASP.net web application.
Theres a method called "GetDeal" in this web service, that returns a "Deal" Object.
The deal object currently looks (for example) like this:
[code]....
This class is in a different assembly: MyCompany.Model
The web service references this assembly.
In my web app, I can call the GetDeal method. This returns Service1.Deal (service1 is just the name of the web reference)
I can access both properties above. I have now changed the Deal class, and added a couple more properties.
However, I can't see these new properties in my web application. I've updated the web service in the web application. I rebuilt the web service several times, tried removing the MyCompany.Model reference and re-addding it etc...
I can't figure out what has changed... This was working - I have changed the model before, and it's updated the reference correctly...

I have a webmethod that has three parameters:
public AuthenticationResult Authenticate(Enum type, string userName, string password) But the problem I had is that if a null/invalid enum is entered for the type variable it throws an error message.
So the obvious solution is to use a string/int instead but I am cannot do this as current users already use the existing webmethod.
So i was thinking:
public AuthenticationResult Authenticate(object type, string userName, string password) and handling the casting myself but the problem I had with this is that now my users do not have access to the Enum type.
So my question is can I publish the enum type without having it as a parameter/return value? Allow the client to access the Enum so they can pass it into the method. Would using a method that returned a type that was my enum work? Or is there a way to catch this custom error: (I dont think so as it appears to be on the client end when converting Enum to xml). The error is: (System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: Instance validation error: '45465' is not a valid value for Enum.)

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 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?

I have a main page with several menu choices, one of which launches an ajax enabled window. The following pattern occurs:If I:
1) Launch site
2) Select menu choice listed on master page that is not ajax enabled
3) Select menu choice that launches ajax enabled popup.
4) close pages
All is OK.If I repeat the steps, but in step 2 I select an ajax enabled page and them launch popup, I get the following error:Message: Sys.ArgumentTypeException: Object of type 'Sys.UI._Timer' cannot be converted to type 'Sys.UI._Timer'.I have spent days on this and have been unable to solve it. If I remove the ajax ToolkitScriptManager and update panels from any of the pages and launch the popup, it works. Can anyone offer some guidance?that are not ajax enabled and then selethat includes an ajax enabled popup window. T

I am new to WCF, I was using web service asmx before. I have trouble on making my wcf JSON ajax service work through http like asmx.Could you help me see what wrong in my code?My WCF services are defined in my website application folder. My aim is to call this service in my aspx page java-script code and return complex object back as JSON to my javascript. I have no problem on doing this through classic asmx web service.
When I try to test it through my browser by type this in the URL , URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc/GetAll. it return "Method not allowed."
But if I type just this URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc, it return this:
WCFCompanyService Service
You have created a service.To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:
svcutil.exe URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc?wsdl
This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:
C#
class Test { static void Main() { HelloClient client = new HelloClient();
[Code]....
This is my Ajax-enabled WCF service code:
[Code]....
This is the web.config service model setting
[Code]....

I have some javascript code that processes json output from asp.net web services built with framework 2.0. Now I need to support data returned from framework 3.5 web services. My javascript code assumes a list of objects as return value, which works fine in 2.0. However In framework 3.5, the list is wrapped in a "d" object. Is there any way I can remove the "d" wrapper and just return the list?

My json response contains json with structure (eg. "[[[],[]]]") but no actual content.
AJAX code:
[Code]....
It definitely recognizes structure (if I change the xml nodes, it reflects in the []'s) but just isn't inserting any content. I tried prefixing the web method with "<ScriptMethod(ResponseFormat:=ResponseFormat.Json)>" but it made no difference.

As it is now I create a JavaScript object and then stringify it, put it in a hidden textbox and my code behind can read this string. I then use JSON.NET to parse the string which works fine. I now try to use ajax to post it to my web service but have some issues with how to send the string. I have tried many ways but gets the common errors like
Invalid JSON primitive: myString.
So I checked this out [URL] and it works with hard coded values but I want to use a variable.
JavaScsript to create the object:
for (var i = 0; i < results.rows.length; i++) {
var row = results.rows.item(i);
var customer = new Object();
customer.id = row['id']
customer.name = row['name']
var customerString = JSON.stringify(customer);
$.ajax({
type: "POST",
url: "synchronise.asmx/synchroniseCustomers",
data: "synchroniseCustomers: " + customerString,
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (xhr, status) {
alert("An error occurred: " + status);
},
success: function (msg) {
alert("success");
}
});
}
WebMethod:
public void synchroniseCustomers(string customerString)
{
JObject o = JObject.Parse(customerString);
string id = (string)o["id"];
string name = (string)o["name"];
If I use data: '{ FirstName: "Dave", LastName: "Ward" }'
in the example above it works but I wish to pass on a string instead.
