webmethod

I have the following problem: The call from a WebMethod is not being done on a project created in Visual Studio 2013 (ASP.NET WebForms Application). If I create a project, for example, in Visual Studio 2008 and migrate to VS 2013 works correctly. The problem only occurs when I create a new project in Visual Studio 2013. There is no error message in the console. The WebMethod is just not being called. Nothing happens. I searched a lot but found nothing about it. ASPX code: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="TestePageMethods._Default" %> <

Im trying to stringify a javascript object and then pass the string as a parameter to a WebMethod in Code Behind.

I'm new to jqgrid finally i've setup a grid. Suppose i need to setup jsonReader so that the grid knows where to get my grid-data in the json return. However i got blank cells after trying for days.

Can any one guide me how to get json data from asp.net webmethod, and consume it in angularJS. app.controller('MainController', ['$scope', function ($scope, $http) { try { $http({ method: 'GET', url: 'ProblemList.aspx/GetProblemList' }) .success(function (data, status, headers, config) { alert(data); }).error(function (data, status, headers, config) { }); } catch (e) { throw e; } I had the same issue, I tried many different ways, this is the way I found it works... ( I think the tricks is a combination of the header config, and the json parameter with "data : {}", I am not sure but It was

Is it possible to place a WebMethod in an ascx.cs file (for a UserControl) and then call it from client-side jQuery code? For some reasons I can't place the WebMethod code in an .asmx or .aspx file. Example: In ArticleList.ascx.cs I have the following code: [WebMethod] public static string HelloWorld() { return "helloWorld"; } In ArticleList.ascx file there I have the call to the WebMethod as follows: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", data: "{}", dataFilter: function(data)//makes it work with 2.0 or 3.5 .net { var msg; if (typeof (JSON) !== 'undefined' &&

i have a ajax request which works well using "POST" but when used "GET" it gives me the following error, {"Message":"An attempt was made to call the method \u0027GetSomething\u0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"} so here is my code, on the client side, function test() { $.ajax({ url:

I declared a WebMethod in my default.aspx.cs file.. [WebMethod] public static void ResetDate() { LoadCallHistory(TheNewDate.Date); } Why must the WebMethod method be declared static? Sean Airey They're static because they are entirely stateless, they don't create an instance of your page's class and nothing is passed to them in the request (i.e. ViewState and form field values). HTTP is stateless by default, ASP.Net does a lot of stuff in the background with ViewState, Session, etc. during a standard page request to make life easier for developers. When a web method is called through AJAX, the
