PageMethods is not defined

Question

I am setting up PageMethods to access server side code using javascript. I am receiving the error \"PageMethods is not defined\" when i debug using firebug. the server side

Answer 1

Page Methods don't work in either Master Pages or User Controls.

If you move the method up one level to you page it should work.

Never really been able to get a definitive answer on this one.

I suspect it has do with the fact that aspx pages inherit from the Page class and the ascx controls inherit from the UserControl class. As to why of that I am not too sure.

Personally I would use a generic handler (.ashx) page and call that through javascript.

Answer 2

set EnablePageMethods="true"

 <ajaxToolkit:ToolkitScriptManager ID="scriptManager" 
                               runat="server" 
                               AsyncPostBackTimeout="99999999"
                               EnablePageMethods="true" />

i hope this will work for you

As far as I understand, PageMethods on usercontrol is not supported and threads below seem to confirm that

ASP.NET AJAX Page Methods from UserControl

But I think there could be a workaround (not sure if that's efficient in your scenario). You can write a OneLine PageMethod in page's code behind which would intern call the Controls Page method. Now you can invoke your page's method from aspx and all set to go.
