ASP.NET Web Forms [WebMethod] not being called by AJAX Post

September 4, 2022 by Magenaut

I’m working on a ASP.NET Web Forms project using bootstrap/jquery 3.4.1 js. I’m having an issue of getting my AJAX Post working. It’s supposed to hit my [WebMethod] within Schedule.aspx, but it’s not. I’ve put down a breakpoint on it and it’s never activated when clicking the save button. The AJAX succeeds and the alert pops up, and I’ve already verified that the stringify data is outputting as expected, but why is it not hitting the [WebMethod]?
