Custom IsAjaxRequest function doesn't work in MVC 6

Question

I'm having a trouble in detecting ajax request in MVC 6 controller, since IsAjaxRequest is not found in MVC 6 I used the following function:

 public static bool IsAjaxRequest(this HttpRequest request)
 {
 if (request == null)
 throw new ArgumentNullException(nameof(request));
 var x = request.Headers["X-Requested-With"];
 if (request.Headers != null)
 return request.Headers["X-Requested-With"] == "XMLHttpRequest";
 return false;
 }

but the function always return false

my jquery code:

 $("ul.menu a").click(function (e) {
 e.preventDefault();
 var url = $(this).attr("href");
 $('#main-container').load(url);
 });

• Mahesh Singh Chouhan: check this may be useful
• Morz: I've already done, but the method always return false.
• rino.batin: Can you see from your browser if the request header contains X-Requested-With? Is the url you are loading from the same domain as the page that is loaded on the browser?

Answer 1

The issue was in the selector, since it was wrong e.preventDefault doesn't work and the request continues normally, that's why it will never be ajax request.
