Question

I am not able to get correct error code in the error handler of AJAX request. Everytime the error occurs, it returns me statusCode = 500. I tried to set it explicitly in my service as HttpContext.Current.Response.StatusCode = 403;, but still it gives me status = 500.

This is how my AJAX request looks like:

$.ajax({
            type: "POST",
            url: "Services/someSvc.asmx/SomeMethod",
            cache: true,
            contentType: "application/json; charset=utf-8",
            data:"{}",
            dataType: "json"
            error: ajaxFailed
        });

        function ajaxFailed(xmlRequest) {
                alert(xmlRequest.status + ' \n\r ' + //This is always 500.
                xmlRequest.statusText + '\n\r' + 
                xmlRequest.responseText);
        }

What am i missing here?

Looks like you were almost there, here is an example [WebMethod] that would throw a StatusCode 403.

    [WebMethod]
    public static string HelloWorld(string name)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.StatusCode = 403;
        return null;
    }

Here is the calling jQuery Code.

    $(document).ready(function ()
    {
        var jsonRequest = { name: "Zach Hunter" };

        $.ajax({
            type: 'POST',
            url: 'Demo.aspx/HelloWorld',
            data: JSON.stringify(jsonRequest),
            contentType: 'application/json; charset=utf-8',
            dataType: 'json',
            success: function (data, text)
            {
                $('#results').html(data.d);
            },
            error: function (request, status, error)
            {
                $('#results').html('Status Code: ' + request.status);
            }
        });
    });

If you don’t return a value as specified in your method signature you’ll get a status code 500 returned.
