calling serverside method from javascript

Question

I want to call server side C# function from javascript.

I used the way given in this article.

This works fine when I did the same steps in a new ASP.NET application.
But when I repeat the same steps in the application on which i am working it give the error:

"PageMethods is Undefined".

I am working on .Net 4.0.

You must have at least one page method in the page class in code behind. Having it in control won't work. — user447356

Have you enabled page methods on your scriptmanager?

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

I did all the things that are given in the article, and its working in a new application. When i do that same in my old website, it doesn't work. I tried it in ascx and aspx both control and page.

Make sure you have a ScriptManager control?

As an alternative to trying to get the PageMethods approach to work, I would recommend switching to the more up to date WCF Script Services:
