Question

I am trying to make an AJax call to a controller method the parameter is null no matter what I try. I have followed all the similar SO posts but to no avail. Sorry if the answer is there, I cant find it. The code I have is…

Ajax Call

    var sguid = $(nTr).attr('id');
    $.ajax({
    url: "/Dashboard/Reporting/GetBlacklistedSoftwareItems",
    type: 'POST',
    dataType: 'json',
    data: JSON.stringify({guid: sguid}),
    statusCode: {
        404: function() {
    alert("page not found");
        }
    },
    success: function (data) {
    //DO Something
    },
    error: function () {
        alert("error");
    }
});

Controller Method

public JsonResult GetBlacklistedSoftwareItems(string guid)
{
    List<DeviceSoftware> ldevice = new List<DeviceSoftware>();
    Guid i = Guid.Parse(guid);
    ReportMethods reportingMethods = new ReportMethods();
    ldevice = reportingMethods.GetNonCompliantApplicationReport(CompanyId);

    DeviceSoftware ds = ldevice.Find(x => x.Device.Guid == i);
    List<DeviceApplication> da = new List<DeviceApplication>();
    if (ds != null)
    {
        da = ds.DeviceApplications;
    }

    return Json(da, JsonRequestBehavior.AllowGet);
}

The method is being hit its just guid is alway null. sguid does hold the data I am trying to pass.
Can someone tell me what I am missing?

Against everything I read I changed

data: JSON.stringify({guid: sguid}),

To

data: {guid: sguid},

Now working.
