Hello, everyone. 

As we know,  we should deal with the request from the client side. there are any methods to handle the client-side request, I can create a ashx file or use web service. hah, I just know these two methods, if you get another methods, please tell me. Thank you very much.

anyway, we need a url to handle the request, now I create a template and a macro with usercontrol, then I insert this marco in the template.

I want to use ajax inside of the usercontrol. How could I implement it? 

I don't know if you have experienced it the same as mine. 

Thank you very much in advanced.
