Object passing with jquery ajax?

Question

I want to pass object to controller action, but it does not work. Object is null, no error. I debugged it and I got the passing parameters.

scripts

$(document).ready(function () {
var IrregularChartParams = {
    MeterId: 2,
    MeterTypeId: 2,
    ReadingTypeId: 4,
    StartDate: "start",
    EndDate: "end",
    DateRangeId: 5
};

var chartParams= JSON.stringify(IrregularChartParams);

$.ajax({
    type: "POST",
    url: app_base_url + 'Graph/GetChart',
    contentType: "application/json;charset=utf-8",
    dataType: "json",
    data: chartParams,
    traditional: true,
    success: function (result) {
        $("#chart").html(result);
    },
    error: function () {
        alert("hatalı");
    }
});
});

controller

public ActionResult _IrregularChart(IrregularChartParams chartParams)
{
    // chartParams is null 
}

debugging time params looking like following:

System.Collections.Specialized.NameValueCollection {System.Web.HttpValueCollection}

Why object is null in controller and why params are looking like above?

UPDATE

DTO

public class IrregularChartParams
{
    public int MeterId { get; set; }
    public int MeterTypeId { get; set; }
    public int ReadingTypeId { get; set; }
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
    public int DateRangeId { get; set; }
}

before it was working, then I change properties names, not it does not work...

Thanks.

you can directly pass object in data opton of ajax no need to stringfy..

try this

data: IrregularChartParams , //here

and get it by POST in you controller

Looking at your DTO, the StartDate and EndDate properties are DateTime objects while you seem to be passing in strings from your JavaScript implementation. This might be a cause for model binding to fail.
