Actually I am trying to learn jQuery Ajax calls to asp.Net webservices.
I have been trying to call the webmethod below:
[code]....
Do I need to serialize my object in some way before setting the 'data' attribute, so that I can call $.ajax() function?

I have a web Method in my C# that is called via Jquery ajax method. The web method should return an object back to the Jquery which will be used to populate. I have tried returning a JsonResult object, the actual object and nothing seems to work! I'm not using MVC (Unfortunately). Is there a way that I can return an object from my web method which can be used by my AJAX method? here is the link for my JQuery AJAX method [URL]

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.

I am new to jqGrid and I have found it difficult to follow the documentation jqGrid Documentation / I cannot figure out how to call a WebMethod when setting up the JQGrid. I have been successful in making an Ajax call to get the data and then setting up the JQGrid with local data. I think its an extra step in the setup process and that I should be able to provide the path to the webmethod using the url property. The editurl property is the same way. I am never actually receiving the post to the server. Attempted JQGrid Setup
function GetData()
{
$('#list').jqGrid({
type: "POST",
url: "Default.aspx/GetUsersJSON",
datatype: "json",
height: 250,
colName: ['Username', 'Email'],
colModel: [
...
}).jqGrid(
'navGrid',
'#pager',
{
edit: true,
add: true,
del: true
});
}
WebMethod
[WebMethod]
public static string GetUsersJSON()
{
var users = new List();
using(UserAdministrationSandboxDataContext uasd = new UserAdministrationSandboxDataContext())
{
users = uasd.GetUserList();
}
JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(users);
}
Current Code I got it working correctly now, but I still have one final question. Why did I have to set the 'repeatitems: false' in order to display the content? Some of the caveats to get this to work include the different ways to setup the ajax request. (Ajax: type) is (jqgrid : mtype) (Ajax: contentType) is (jqgrid : ajaxGridOptions: { contentType: })
And finally understanding the documentation from the documentation on how to setup the JSONReader.
function GetUserDataFromServer()
{
$('#list').jqGrid({
url: "Default.aspx/GetUsersJSON",
mtype: 'POST',
ajaxGridOptions: { contentType: "application/json" },
datatype: "json",
serializeGridData: function (postData)
{
return JSON.stringify(postData);
},
jsonReader: {
root: function (obj) { return obj.d; },
page: function (obj) { return 1; },
total: function (obj) { return 1; },
records: function (obj) { return obj.d.length; },
id:'0',
cell:'',
repeatitems: false
},
datatype: "json",
height: 250,
colName: ['Username', 'Email'],
colModel: [
{
name: 'Username',
index: 'Username',
width: 100,
editable: true
},
{
name: 'Email',
index: 'Email',
width: 220,
editable: true
},
{
name: 'IsLockedOut',
index: 'IsLockedOut',
width: 100,
editable: true,
edittype: 'checkbox'
}
],
caption: "Users"
})
}
Web Method
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static List GetUsersJSON()
{
using (UserAdministrationSandboxDataContext uasd = new UserAdministrationSandboxDataContext())
{
return uasd.GetUserList();
}
}

XP Pro,aspnet 2, IIS, Oracle I have a primary webpage that displays a tab and some summary data. The tab uses an iframe and the summary data is loaded by an async WebMethod call back to C#. The iframe page takes a short while to load depending on how much data is in there (sometimes upto 20 seconds?). The WebMethod call, or at least the content of it, is very fast. BUT, the WebMethod call won't return until basically the iframe has finished loading.
I've verified through Fiddler that the browser is initiating both requests at basically the same time. It's initiating the iframe call first followed immediately by the WebMethod call within the same second. My understanding is that browsers are limited to only two calls at once.
If I set a breakpoint at the end of my WebMethod call (even commenting out ALL it's guts so it just returns an empty string), that breakpoint won't fire until the aspnet page serving up the iframe has finished. Using threads window, I see both calls at the server. I just don't understand why the server won't actually run the Webmethod call until the first call has finished. I've searched the code looking Monitor.Enter, lock, etc to make sure nobody has inserted any other type of blocking code and I can't find anything. I've basically emptied out the WebMethod call and it just returns a string, but no matter what I do, it just won't return as fast as it can. If I comment out the iframe, then the WebMethod call returns within 2 seconds. With the iframe, it "looks" like the the webmethod call won't return until the iframe has finished.
1) Does aspnet only process one request per aspnet session id? Is it FIFO? I figured the webserver would just process requests and return each request as fast as it can.
2) What else can I do to get that summary data to return faster (but not actually loading and putting the data into the very first primary page) ?

I am calling a WebMethod from this code:
if($(this).attr("checked")) {
..
MyWebMethod(variable1, variable2, onSuccessFunction);
}
The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do:
MyWebMethod(variable1, variable2, onSuccessFunction($(this)));
I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?

I am currently working with ASP.NET and the person who designed the form has used all Server Controls for things like TextBoxes and Dropdowns etc when really they are not providing postbacks.. Some of the dropdowns and textboxes are values that I need only in jQuery so as far as I can see there are no drawbacks to coverting these controls to standard html controls rather than ASP.NET server controls?
I suppose I will need to continue to have my GetDataGrid button as a server control because I will need it to postback (and receive PageLoad events etc - all asp.net events) to update the GridView? Or would it be possible to use the GridView (server control) from a Webmethod and call it via Jquery?
Of course in my webmethod I would need to the instance of the gridview to add the datasource - but I don't see how this would be possible without being in the ASP.NET events - or maybe I wrong?
The other thing I thought of was changing the GetGridView button to a standard HTML and calling the javascript postback from the client click event?? This way it would do a real postback and I would end up in Page_load.
Taking everything into effect i don't want to the change the GridView asp.net control as it funcions well as an asp.net server control but i am unsure how i would do this.
I remember a document being available that said "how to use asp.net webforms without server controls" but i can't seem to find it. I suppose using webforms like asp.net MVC - but i can't change the project to MVC - its out of my control.

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

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?
