CAllback Http handler http module

Hi all,

Can anybody tell me how to generate callback.This call back should NOT be in on aspx page .

I this its solution is Http module or Http handler but i dont have idea to implement .Give me some reference and sample code or examples for implementing call back using http handlers or httpmodule

thanks

Could you please describe in more detail what you want? A callback (as in ICallbackEventHandler) that is not on a page does not make sense.

I HAVE A WEB CONTROL CLASS LIBRARY IN WHICH I HAVE A .js FILE ADDED AS RESOURCE FILE . FROM THIS FILE I WANT TO SEND A CALL BACK AS I WANT TO USE "AJAX". BUT AS FAR I KNOW I REQUIRES A .aspx.cs PAGE WHICH I CAN'T ADD IN THE CLASS LIBRARY. HOW WILL I DO THIS TASK.

ANY KIND OF HELP IS APPRECIATED

ICallbackEventtHandler can be implmented in a Controt, it not true that it can be only implmented in a page. For more details of creating controls with ICallbackeventHandler checkout this articlehttp://msdn.microsoft.com/msdnmag/issues/05/01/CuttingEdge/default.aspx
