Question

Is there any way to use ajax I’m using Jquery for this) with asp.net webforms without having to run through the pages life cycle?

Answer 1

If you’re using jQuery, as you mentioned, you can use jQuery to call Page Methods directly, without incurring the overhead of MicrosoftAjax.js and the service proxy it generates to enable the PageMethods.MethodName() syntax.

Given a static [WebMethod] decorated method in PageName.aspx that’s called MethodName, this is an example of how you could call it on the client-side:

$.ajax({
  type: "POST",
  url: "PageName.aspx/MethodName",
  data: "{}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg) {
    // Do something interesting with msg.d here.
  }
});
