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?

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?

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

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)

    {

      alert(result);

    }

  </script>

excellent, thanks

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?

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?

just what i was looking for thanks

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?

Excellent. Works for me as is in the orignal post. (not using security).

Excellent,it's working fine after Enabling pagemethods in script manager.Thank's for the post.

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

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.

Hello...I have the same problem as Sqeeb ... using Master Page it seem not works

@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: http://xeno.extendev.org/2010/01/control-methods-for-aspnet-ajax.html

And you can get the source code/samples here: http://controlmethods.codeplex.com/

i was trying to implement the same functionality in VB.net but it was throwing an error saying "Microsoft JScript runtime error: 'PageMethods' is undefined"

Thanks Excellent

I did same way, you have done .but it is not working .Kindly give me the solution.
