Calling a static "page method" from Javascript using MS AJAX

Atlas gave us the ability to easily call Web Services from JavaScript. MS AJAX has gone one step further! We can now call methods in the codebehine of the current page from Javascript. Here's how:

This is designed for v1.0.61025.0 of AJAXExtensionsToolbox.dll

Enable Page Methods on your ScriptManager

Set the EnablePageMethods attribute to true

<asp:ScriptManager ID="ScriptManager1" 
    EnablePartialRendering="true" runat="server" />

Mark your method as static and give it the WebMethod attribute

The method has to be declared static. It must also be marked with the WebMethod attribute. You'll probably find that you need to include System.Web.Services

using System.Web.Services;
public static string MyMethod(string name)
    return "Hello " + name;

Call it from Javascript

To call the method from javascript you need to append PageMethods. to the front of the method name.

    function test(){
        alert(PageMethods.MyMethod("Paul Hayman"));

This is cool! What about security? If you needed to be logged in to execute "MyMethod", does the xmlhttpRequest issued contain a session cookie with it?

This is something I considered myself.. what I decided to do in my implementation was check that the user was in one of the allowed rolegroups for the operation.

To clarify, I used this for passing back information from a content editor. So, a check to see if the user was an Administrator or Editor was sufficient.

Hi, I get an exception "PageMethods is not defined". Any ideas? is PageMethods an internal js object or am I missing something?

phayman said:

After discussing it with Wouter we discovered that his problem was caused by the WebMethod being located inside a UserControl, not the Page.

It would appear that you can't call a WebMethod located in a UserControl.

If anyone knows how to achieve this, post a comment.

I'm able to hit the server method, but it is returning me "undefined" instead of the string "Hello whatever".

What am I doing wrong?

Nelero said:

I'm facing with the same problem as Andres V. When I call my webservice method, returning a string, i get "undefined"...

Gerard van de Ven said:

Yes, the actual way of doing this is to use a "onComplete" because of the asynchronous call, as follows:

  <script type="text/javascript">

    function test(){

        PageMethods.MyMethod("Gerard van de Ven", OnMyMethodComplete);


    function OnMyMethodComplete(result, userContext, methodName)

Not marking the PageMethod as STATIC is quite a common mistake, be sure to mark your metdod as STATIC

I am having a problem calling my webmethod from javascript. Everything was working fine until I implemented security. Now when I do PageMethod.TestCall("something"); I get a 401 - Authentication Error. Do you have any ideas on how to resolve this problem?

Lkeel said:

I am trying to make a call back to my server from the javascript the same as you have here. My problem is that now that I have secured my website with forms authentication, the call back to the server is throwing a 401-Authentication error. Have you seen this before? Do you have a work around for this problem?

Having problems here....

I'm using the same code verbadum (enabling scriptManager page methods, your javaScript and codebehind method) on a master page. For some reason, it's not liking PageMethods and won't call the server side function. Any Suggestions?

Deepa Sehgal said:

its realy helpful for me but you havn't explained why it is necessary to make static methods and what is the purpose of writing WebMethod

Iti Sharma said:

I tried using both above mentioned methods but none of them worked. If, I write <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" EnablePartialRendering="true" /> , then page doesn't load. Otherwise, it is executing javascript but not calling PageMethods.

Please tell me any solution.

@phayman - ASP.NET AJAX does not facilitate a means to use static WebMethods in UserControls but I too have been very interested in this (mostly for the sake of encapsulating my control's logic within my control's class). Since there was no solution I set out to find a way to do it, which I've just recently finished. There's not much documentation on my solution yet, but if you want to take a peak I'd be interested in your thoughts.

I've written a post about my attempts here:
