If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
I using this Ajax.BeginForm
<% using( Ajax.BeginForm( "Create","Mandate",
new AjaxOptions( ) {
OnSuccess = "GoToMandates",

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.
View 15 RepliesI have .aspx page methods with return type of string, which work great. I am using some jQuery ajax, and some .NET Ajax "PageMethods.methodName" syntax from the client side to successfully call these page methods. I need to return xml from a page method.... I would LOVE to be able to return system.Xml.Linq.XElement type from page method. I get a serialization circular reference error when I attempt to return XElement or XDocument. I don't really want to return XML.ToString() to client, and then convert string to xml in javascript. What return page method return type(s) would allow me to retrieve xml with jQuery ajax call? I know json is the alternative, but will not give me what I need this time.

View 2 RepliesI'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;">

@foreach (var user in Model)
{

<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>

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'm using Ajax.Begin form with MVC validation. When I'm in the server code and there's a validation error then ModelState.IsValid is false and that's good.If I have OnSuccess defined in my AjaxOptions why does my OnSuccess function get called when the ModelState is not valid?In my parital view:
using (Ajax.BeginForm("ProfileEdit",
new { controller =
"Account", action =
"ProfileEdit", id =
ViewData["ProfileID"]
}, new
AjaxOptions { UpdateTargetId
= "profileEdit", OnSuccess
= "OnSuccess" }))
In my controller I always just return PartialView();
I just want to display a success message in the view but OnSuccess gets called even if there is a modelstate error. If I try to throw a HttpException then I lose my ValidationSummary and other error messages.
To work around, I'm setting a ViewData["Success"] and displaying the message div in the .ascx if ViewData["Success"] != null.
I'm trying to call web service function via GET method using jQuery, but having a problem. This is a web service code:
[WebService(Namespace = "http://something.com/samples")]
[ScriptService]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [Code]....
And I get an error because of this (error handler is called).
In GridViewData.aspx.cs I have a method I want to call inside a javacsript function.

Now hears the kicker, I am mostly using jqUery as UpdateInsertData() is a jquery Call and works fine. How do I use ValidateNameUpdateable to call jQuery to return the value from the c# method. . I believe this issue is with my jQuery Call as its just posting and I need to do a $.get or something?
function ValidateNameUpdateable()
{
$(document).ready(function ()
{
$.post("GridViewData.aspx")
});
}
I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

I am fairly new to MVC and just trying to achieve something which I think shouldn't be too complicated to achieve. Just want to know what the best approach for that is. I have an Event-RSVP application (NerdDinner kind) where you go to view details of the event and then click on an AJAX link that will RSVP you for the event.
<%
if (Model.HasRSVP(Context.User.Identity.Name))
{
%>
<p>
You are registered for this event!
<%:
Ajax.ActionLink("Click here if you can't make it!", "CancelRegistration", "RSVP", new { id = Model.RSVPs.FirstOrDefault(r => r.AttendeeName.ToLower() == User.Identity.Name.ToLower()).RSVPID }, new AjaxOptions { UpdateTargetId = "QuickRegister"})
%>
</p>
<%
}
else
{
%>

I have a problem trying to retrieve a return value from a javascript function and using it from my code behind. The problem is after I call my UpdatePanel.Update() method and call return, I can't continue as I have ended execution of the page by calling return. Please find an example of my code:
[Code]....
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

View 1 RepliesI am using ASP.NET MVC with jquery. I have the following MVC Action that returns a partial page on Success. On Application Error, I am not sure what to send it for correctly handling it at the client side.
public ActionResult LoadFilterSet(int filterSetId)
