How to check if request is ajax or not in codebehind - ASP.NET Webforms

Question

I tried the Request.IsAjaxRequest but this does not exist in WebForms. I am making a JQuery ajax call. How do I check if this is a ajax request or not in C#?

Answer 1

Decorate your class with [WebMethod(EnableSession = true)]syntax like if you write the following function in code behind and call the same function from ajax call you will be sure.

[WebMethod(EnableSession = true)]
    public static void   getData(string JSONFirstData,string JSONSecondData, string JSONThirdData, string JSONForthData, ...)
    {
       //code
    }

in Ajax URL be like URL :'/Codebehind.aspx/getData'
