I've put together a very basic tutorial for a jQuery Mobile app with a very basic tutorial using the Web Api with VS 2013 and VB.NET. The Web Api is just for use with my UI within my app as a way to bridge between html and asp.net. It works perfectly on my development machine but the Web Api part fails when I move it to my hosting service (WinHost). I assume that there is a web.config entry that will fix this - but, I'm totally lost on this point. The html/jQuery code is:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">

var uri = 'api/class1s';
function formatItem(item) {
return item.field1;
}
function find() {
var id = $('#prodId').val();
$.getJSON(uri + '/' + id)
.done(function (data) {
$('#product').text(formatItem(data));
})
.fail(function (jqXHR, textStatus, err) {
$('#product').text('Error: ' + err);
});
}

There is also a WebApiConfig:
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Web.Http
Public Module WebApiConfig
Public Sub Register(ByVal config As HttpConfiguration)
' Web API configuration and services
' Web API routes
config.MapHttpAttributeRoutes()
config.Routes.MapHttpRoute(
name:="DefaultApi",
routeTemplate:="api/{controller}/{id}",
defaults:=New With {.id = RouteParameter.Optional}
)
End Sub
End Module
There is also a class to define the data and a controller to populate data and return data via the Web Api.
These should not affect this problem (and work perfectly on my desktop PC).
Otherwise, this is just a standard VS2013 ASP.Net 4.5.1 project using an empty website with the Web Api option selected.
Is there a way to get this program to work on the hosting service?
I've been working on this site on VS Studio for Web 2012. Most of it is HTML and ASP, but I've included a DayPilot calendar that I downloaded from SourceForge. I, apparently, must DataBind the calendar to my SQL server, so that users can login and set aside times for themselves on the calendar. I've used just about every recommended code I can find on the Net, but none seem to work on the Calendar page.
Here is the aspx page and the aspx.vb page codes:

This need to be

Can we see the Databind function that is called by PageLoad?
I had an issue similar to this when I was working on a C# asp.net application. I created a method to bind the data from a dataset that contained a table of cards. When loading the table "NullReferenceException was unhandled by user code" was thrown and upon looking at the table I could see that a null value was being held.
When you are debugging and the exception is thrown, what is being shown as the held value of the data table?
If it is null then your table is not referring to an object.

The problems might be that i used to have AjaxControlToolkit in my project but later i use jquery instead. so somewhere in the project might try to add Ajaxcontroltoolkit which i can't find it. i don't know how to fix this error. i have tried to add bin file of ajaxcontroltoolkit back but it seems to not work.
this solution works for me:
The error on client was:
SCRIPT5022: ASP.NET Ajax client-side framework failed to load.
SCRIPT5009: 'Sys' is undefined
After many time to mining the websites, and more solutions, i solve the problem:
the solution for .NET 4.0 is:
Set EnableCdn property of script manager to true, Like this:
<asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="true">
Next Solution and Better Solution is:
add this handler to your web.config
<system.webServer>
<handlers>
<remove name="WebServiceHandlerFactory-Integrated"/>
<remove name="ScriptHandlerFactory"/>
<remove name="ScriptHandlerFactoryAppServices"/>
<remove name="ScriptResource"/>
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</handlers>
</system.webServer>
Sys undefined means that you're not getting the client side files loaded on your browser.
Solution 1:
<add verb="GET"
path="ScriptResource.axd"
type="Microsoft.Web.Handlers.ScriptResourceHandler"
validate="false"/>
Solution 2: If you don't have this, add this too under <assemblies>
<add assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
Solution3: If that doesn't work too, try deleting files from your "bin" folder and rebuild the solution and clear the cache of your browser.
Solution 4: Add this to your web.config
<location path="ScriptResource.axd">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
for telerik web resources use this code:
<location path="Telerik.Web.UI.WebResource.axd">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
I had enabled WebForms Routing and forgot to add the exception for resources:
routes.Ignore("{resource}.axd/{*pathInfo}");
Another possible cause is script combining/compression in IE 8 & 9. In web.config at the top level (within Configuration), put
<system.web.extensions>
<scripting>
<scriptResourceHandler enableCompression="false" enableCaching="true" />
</scripting>
</system.web.extensions>
On your ToolKitScriptManager put CombineScripts=False, e.g.
<asp:ToolkitScriptManager runat="server" CombineScripts="False">
</asp:ToolkitScriptManager>
see http://robmzd.blogspot.com/2010/02/invalid-character-error.html which is where I figured out the problem
Add EnableScriptCombine="False" to your RadScriptManager as follows:
<telerik:RadScriptManager ID="RadScriptManager1" EnableScriptCombine="False" runat="server" />
I had this problem when I moved my forms to a new server. I spent hours to find the solution.
The problem was that the new server has ASP.NET 4.0 and my web.config was ASP.NET 3.5. So I made a new web.config and everything is ok now.
Simply add the <handlers> section as shown below in your web.config within <system.webServer> and this will fix the problem in no time.
<system.webServer>
.
.
.
<handlers>
<remove name="WebServiceHandlerFactory-Integrated"/>
<remove name="ScriptHandlerFactory"/>
<remove name="ScriptHandlerFactoryAppServices"/>
<remove name="ScriptResource"/>
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add name="ScriptResource" verb="GET,HEAD" path="ScriptResource.axd" preCondition="integratedMode" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</handlers>
</system.webServer>
For me it was the problem with Global.asax code,
Just check below condition before validating session in Application_PreRequestHandlerExecute
Request.Path.ToUpper() != Constants.AliasName.ToUpper() + "SCRIPTRESOURCE.AXD"
Functional code is shown below,
protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e)
{
if ((Request.Path != Constants.DebugLoginUrl) &&
(Request.Path != Constants.SessionTimeOut) &&
(Request.Path.ToUpper() != Constants.AliasName.ToUpper() + "TRACE.AXD") &&
(Request.Path.ToUpper() != Constants.AliasName.ToUpper() + "SCRIPTRESOURCE.AXD"))
{
// to prevent check of HTTP HANDLER FLUSH - Session State is Invalid
if (HttpContext.Current.Session != null)
{
if (Session[Constants.personId] == null)
{
//your code
}
else
{
Response.Redirect(Constants.SessionTimeOut);
}
}
}
In my case the Ajax loading error occurred only if I reloaded the page, not when the page was loaded for the first time.
Looking at the content in the tag in Site.Master, I noticed that only some of the items had Path attribute set. So, I updated MsAjaxBundle to this: and the problem went away. I also had to modify the WebFormsBundle the same way and now reloading the page works.
What worked for me was to download ASP.NET Ajax from Microsoft.
You might also need to explicitly browse for the correct dll version when you add reference e.g.
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1\System.Web.Extensions.dll
I set Application Pool as ASP.NET 4.0 Classic during installation.
well i just changed RadScriptManger to Simple asp:ScriptManager and it works
Before:
<telerik:RadScriptManager ID="RadScriptManager1" EnableCdn="true" runat="server" />
After
<asp:ScriptManager ID="scrReg" EnablePartialRendering="true" runat="server"></asp:ScriptManager>
Hope it helps
And here's another cause. I installed MySQL Connector/net 6.9.5. Later I started getting the dreaded 'sys undefined' for everything in some, but not all, projects in IE. Many, many hours later I tried Chrome and Opera and the first page opened fine but on post back all the session variables had vanished. That's when the penny finally dropped - Connector/net must have set itself up the session state provider but I had nothing for session state in web.config for the failing projects. Sessionstate inproc fixed it immediately. At least I think that's what happened...
In my case, I had ended up with the mentioned handlers in <httpHandlers> as well as in <handlers>.
Removing the <httpHandlers> section fixed it.
After adding System.Web.MVC reference to my ASP.NET and added default route in global.asax
i.e.
RouteTable.Routes.MapRoute("Default", "{controller}/{action}/{id}",
new { controller = "new", action = "Index", id = "" });
}
Started getting the error
Added below line to global.asax.cs to resolve it
RouteTable.Routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
For anyone working with the Visual Studio 2015 ASP.NET 4.5 WebForms Web Application project template which bundles the ASP.NET AJAX scripts:
https://stackoverflow.com/a/47673606/313935
for me web config was correct.
if web config is correct then.
check your IIS App pool settings in my case App pool pipeline was selected as the classic I made pipeline integrated and it started working.
Go to iis -> rightclick on your application pool -> advance settings ->
Managed Pipelined Mode -> "integrated" -> ok
I am using Visual Studio 2015 ASP.NET 4.5 Web Forms Web Application project and apparently a bad route in an API Controller will also cause this error. I fixed the route and the error went away.
It certainly would be nice for a more descriptive error message as to why the client framework won't load. I spent hours checking web.config settings, clearing the .net temporary directories, checking global.ascx, etc.. The strange thing is while IE 11 died while loading default.aspx, chrome was able to load default.aspx and the web site.
Try changing on the web.config the compilation to false:
<compilation debug="false" targetFramework="4.5">
If none of these answers work for you then you might be in my situation.
Ok, so for me the issue was caused by the ssl certificate expiring today, so after I renewed it then these errors went away.
In the process of converting a page from normal postbacks to AJAX-calls (using JavaScript to load/control the UI entirely and use ASP.Net strictly as a backend), I found myself wanting to replace a GridView with a AJAX-sourced dataset.
I currently use DataTables to prettify the GridView, and there exists an option in the API to use AJAX to remotely source the data for the table. The API needs a JSON object returned, although it appears that I can supply a callback for the fnServerData option which would allow me to convert the XML response to the requisite JSON datasource.
"So", I thought, "I might as well slap together a <WebMethod()> to return the datasource..." and while I've written several <WebMethod()> functions in the past, I've always added a new ASMX file (with a custom class to drive it) or extended an existing one where it made sense to do so. With this specific page, there is no need to make the datasource for this table accessible outside the context of the page, so I thought I would try to add the <WebMethod()> to code-behind of the ASPX page.
There appear to be several examples on the web of programmers successfully pulling off what I have been pulling my hair out over.
I have followed every example that I can find and none are working for me. I have put together an extremely simple example in the hopes that someone can either point out where I'm going wrong or confirm that ASP.Net 2.0 simply won't work in this manner.

Does anyone have any ideas:
What I am doing incorrectly?
Or is ASP.Net 2.0 is incapable of using a <WebMethod()> in an ASPX page?
Looks like your data is being provided incorrectly. Should be:
data: "{' + "What" + ':'" + "World" + "'}",
I singled the "What" and "World" out because I assume those are variable values from elsewhere.
so if:
var x = "World";
.ajax(){
.....
.data: "{'What':'" + x + "'}",
would be correct

Okay, I finally found the complete answer (and +1 to #TheGeekYouNeed for what turned out to be part of the solution).
ASP.Net 2.0 does not support WebMethod() in an ASPX page out-of-the-box. There were three steps total (for me) to enable support of WebMethod() in an ASPX page.
Download and install Microsoft ASP.NET 2.0 AJAX Extensions 1.0.
Add the following to the <httpModules> section of the <system.web> section in my web.config.
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
stringify the JavaScript object being passed to the WebMethod() (and ergo, props to #TheGeekYouNeed). jQuery will automatically convert a JavaScript object to key/value pairs for the query string. The AJAX Extensions, on the other hand, effectively require that a JavaScript object be stringified into JSON (not parsed into key/value pairs for POST[ing] or GET[ting]) as the HTTP Content-Type header must be set to application/json. Since jQuery will not convert data of type string, the JavaScript object must first be stringified into JSON. The JSON string can then be passed with impunity to the AJAX Extensions. There's a lot of information about the stringification being necessary on the web, just search for Invalid JSON primitive. Personally, I thought the best explanation came from Dave Ward over at encosia.com.
UPDATE:
I ran into the same problem on my production server (running the .Net 4.0 Framework on IIS7). To correct the problem on the production server, I had to add the following to the web.config under the <configuration> element:
<system.webServer>
<modules>
<add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</modules>
<handlers>
<remove name="WebServiceHandlerFactory-Integrated"/>
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</handlers>
</system.webServer>
Exactly working.
I was researching this problem since last week.
because my local having .NET 4 but due to web server my source has to develop in .Net 2.0
What I have done.
Microsoft ASP.NET 2.0 AJAX Extensions 1.0.
WEB.CONFIG updated/appended exactly what given in [LINK][1] [1]: http://www.asp.net/AJAX/Documentation/Live/ConfiguringASPNETAJAX.aspx
I have seen ASP.NET MVC Without Visual Studio, which asks,
Is it possible to produce a website based on ASP.NET MVC, without using Visual Studio?
And the accepted answer is, yes.
Ok, next question: how?
Here's an analogy. If I want to create an ASP.NET Webforms page, I load up my favorite text editor, create a file named Something.aspx. Then I insert into that file, some boilerplate:
<%# Page Language="C#"
Debug="true"
Trace="false"
Src="Sourcefile.cs"
Inherits="My.Namespace.ContentsPage"
%>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Title goes here </title>
<link rel="stylesheet" type="text/css" href="css/style.css"></link>
<style type="text/css">
#elementid {
font-size: 9pt;
color: Navy;
... more css ...
}
</style>
<script type="text/javascript" language='javascript'>
// insert javascript here.
</script>
</head>
<body>
<asp:Literal Id='Holder' runat='server'/>
<br/>
<div id='msgs'></div>
</body>
</html>
Then I also create the Sourcefile.cs file:
namespace My.Namespace
{
using System;
using System.Web;
using System.Xml;
// etc...
public class ContentsPage : System.Web.UI.Page
{
protected System.Web.UI.WebControls.Literal Holder;
void Page_Load(Object sender, EventArgs e)
{
// page load logic here
}
}
}
And that is a working ASPNET page, created in a text editor. Drop it into an IIS virtual directory, and it's working.
What do I have to do, to make a basic, hello, World ASPNET MVC app, in a text editor? (without Visual Studio)
Suppose I want a basic MVC app with a controller, one view, and a simple model. What files would I need to create, and what would go into them?
ok, I examined Walther's tutorial and got a basic MVC site running.
The files required were:
Global.asax
App_Code\Global.asax.cs
App_Code\Controller.cs
Views\HelloWorld\Sample.aspx
web.config
That's it.
Inside the Global.asax, I provide this boilerplate:
<%# Application Inherits="MvcApplication1.MvcApplication" Language="C#" %>
And that MvcApplication class is defined in a module called Global.asax.cs which must be placed into the App_Code directory. The contents are like this:
using System.Web.Mvc;
using System.Web.Routing;
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{arg}", // URL with parameters
new { // Parameter defaults
controller = "HelloWorld",
action = "Index",
arg = "" } );
}
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
}
The Controller.cs provides the logic to handle the various requests. In this simple example, the controller class is like this:
using System.Web.Mvc;
namespace MvcApplication1.Controllers
{
public class HelloWorldController : Controller
{
public string Index()
{
return "Hmmmmm...."; // coerced to ActionResult
}
public ActionResult English()
{
return Content("<h2>Hi!</h2>");
}
public ActionResult Italiano()
{
return Content("<h2>Ciao!</h2>");
}
public ViewResult Sample()
{
return View(); // requires \Views\HelloWorld\Sample.aspx
}
}
}
The Controller class must be named XxxxxController, where the Xxxxx portion defines the segment in the URL path. For a controller called HelloWorldController, the URL path segment is HelloWorld. Each public method in the Controller class is an action; the method is called when that method name is included in another segment in the url path . So for the above controller, these URLs would result in invoking the various methods:
http:/ /server/root/HelloWorld (the default "action")
http:/ /server/root/HelloWorld/Index (same as above)
http:/ /server/root/HelloWorld/English
http:/ /server/root/HelloWorld/Italiano
http:/ /server/root/HelloWorld/Sample (a view, implemented as Sample.aspx)
Each method returns an Action result, one of the following: View (aspx page), Redirect, Empty, File (various options), Json, Content (arbitrary text), and Javascript.
The View pages, such as Sample.aspx in this case, must derive from System.Web.Mvc.ViewPage.
<%# Page Language="C#"
Debug="true"
Trace="false"
Inherits="System.Web.Mvc.ViewPage"
%>
That's it! Dropping the above content into an IIS vdir gives me a working ASPNET MVC site.
(Well, I also need the web.config file, which has 8k of configuration in it. All this source code and configuration is available to browse or download.)
And then I can add other static content: js, css, images and whatever else I like.
You would do exactly what you did above, because you wouldn't use a model or controller in a hello world app.
All visual studio does is provide you with file creation wizards, so in theory, all you need to do is create the right files. If you want detailed specifications for the MVC project structure, good luck, most documentation is written on the assumption you are using visual studio, but you might be able to go through a tutorial step by step, and puzzle it out.
Your best bet is to find a downloadable demo project, use visual studio to reverse engineer the project structure, or try one of the open source .net IDE.
Well, this is how the default VS skeleton for an MVC 1.x app looks like:
Content
Site.css
Controllers
AccountController.cs
HomeController.cs
Models
Scripts
(all the jquery scripts)
MicrosoftAjax.js
MicrosoftMvcAjax.js
Views
web.config
Account
ChangePassword.aspx
ChangePasswordSuccess.aspx
LogOn.aspx
Register.aspx
Home
About.aspx
Index.aspx
Shared
Error.aspx
LogOnUserControl.ascx
Site.master
Default.aspx
Global.asax
web.config
Dunno if that's what you're looking for... the key here is obviously the web.config file.
Note: if you added namespace you must have an assembly.
