Dear Experts,

I have a question regarding the usage of ajax post call while using the MapPageRoute code in global.asax .

I'll show you some example that i have used.

In the Global.asax File Code looks like this.

protected void Application_Start(object sender, EventArgs e)
       {

           RouteTable.Routes.MapPageRoute("ICPDR", "InitialClaimReport", "~/Accounts/PC/Initial_Claim_Report.aspx");

       }

And in the Js File Look like this.

$.ajax({
       "dataType": 'json',
       "contentType": "application/json; charset=utf-8",
       "type": "POST",
       "url": "InitialClaimReport/populate_User/",
       "data": {},
       "success":
           function (json) {

               $('#ddl_User').find('option').remove();
               $("#ddl_User").append('<option value="0"></option>');
               $.each(JSON.parse(json.d).list, function (key, val) {

                   $("#ddl_User").append('<option value="' + val.ID + '">' + val.User+ '</option>');


               });

           },
       "error": function (xhr, status, p3, p4) {
           var err = "Error " + " " + status + " " + p3 + " " + p4;
           if (xhr.responseText && xhr.responseText[0] == "{")
               err = JSON.parse(xhr.responseText).message;
           alert(err);
       }
   });

And in the Code behind

[WebMethod(EnableSession = true)]       
        public static string populate_User()
        {

            try
            {
                BLL_Users objusr_BLL = new BLL_Users();                
                return objpractice_BLL.Fetch_UserList();

            }
            catch (Exception ex)
            {
                
                throw;
            }



        }

POST http://localhost:7777/InitialClaimReport/populate_User 404 (Not Found)

You are accessing it via GET and thats why you are getting 404 .Decorate you method as below with HttpPost attribute

[HttpPost]
[WebMethod(EnableSession = true)]
public static string populate_User()
{

try
{
BLL_Users objusr_BLL = new BLL_Users();
return objpractice_BLL.Fetch_UserList();

}
catch (Exception ex)
{

throw;
}

}

In markup view/fontend page, Have you put every your $.ajax inside $(document).ready(function(){
$.ajax({});
}) for automatic calling or event binding to control that said.

one more things i check out this is mistakes
 
url: "InitialClaimReport/populate_User",       

Do not put "" (double quotes) to enclosed 'url' for method naming convention in ajax calling, and there should be not "/" after "populate_User"

- Do not use "static" when you calling ajax from fontend page/markup view, it will not work from my experience. Better bundles these coding in SVC file to work.

[WebMethod]
[WebInvoke(Method= "POST", ResponseFormat = WebMessageFormat.Json)]
public string populate_User()
        {
 
            try
            {
                BLL_Users objusr_BLL = new BLL_Users();                
                return objpractice_BLL.Fetch_UserList();
 
            }
            catch (Exception ex)
            {
                
                throw;
            }
        }
