I need to simply passed the json data which is created in controller to view my codes are as follow:

My Model: Machines.cs In my model I get the dates as a string and parse them to datetime. Parsing operation is successful when I hit a breakpoint there,I see the result.

   public class Machines
{
    [Key]
    public int AutoKey;
    public string MachineGroup;
    public DateTime StartDate;
    public DateTime EndDate;
    public int Duration;
    public List<Machines> SqlAccessParameter(string startDate,string endDate)
    {
        DateTime sDate = DateTime.Parse(startDate);
        DateTime eDate = DateTime.Parse(endDate);
        string connstr = "Data Source=USER-BILGISAYAR;Initial Catalog=Report;Integrated Security=True";
        SqlConnection myConnection = new SqlConnection(connstr);
        myConnection.Open();
        SqlCommand myCommand = new SqlCommand("DateRange", myConnection);
        myCommand.CommandType = CommandType.StoredProcedure;
        myCommand.Parameters.Add("@SP_startDate", SqlDbType.DateTime).Value = sDate;
        myCommand.Parameters.Add("@SP_endDate", SqlDbType.DateTime).Value = eDate;

        SqlDataAdapter dataAdapter = new SqlDataAdapter();
        myCommand.ExecuteNonQuery();
        dataAdapter.SelectCommand = myCommand;

        DataSet dSet = new DataSet();
        dataAdapter.Fill(dSet);

        myConnection.Close();

        List<Machines> machinePost = new List<Machines>();
        foreach (DataRow row in dSet.Tables[0].Rows)
        {
            Machines mac = new Machines();
            mac.AutoKey = (int)row["AUTOKEY"];
            mac.MachineGroup = (string)row["MACHINEGROUP"];
            mac.Duration = (int)row["DURATION"];
            mac.StartDate = (DateTime)row["STARTTIME"];
            mac.EndDate = (DateTime)row["ENDTIME"];
            machinePost.Add(mac);
        }
        return machinePost;
    }
}

}

My controller: MachinesController.cs

         public ActionResult MachineParameter()
       {
        Machines model = new Machines();
        return View("Index",model);
       }

My View:Index In my view I try to draw a chart according to data that is in the user specified date range but it is not successful.

@model DenemeReport.Models.Machines
@{
    ViewBag.Title = "Index";
 }

 <head>
<title>Intro</title>

<script src="~/Scripts/jquery-1.8.3.min.js"></script>
<script src="~/Scripts/kendo/kendo.all.min.js"></script>
<link href="~/Scripts/kendo/kendo.common.min.css" rel="stylesheet" />
<link href="~/Scripts/kendo/kendo.default.min.css" rel="stylesheet" />

 </head>
   <div>

   Start Date:  <input type="text" id="start" name="start" />

   End Date: <input type="text" id="end" name="end" />

   </div>
   <input type="button" value="OK" onclick="CallAjaxFunction()" />

 <body>
<div id="chart"></div>
<script>

    function CallAjaxFunction() {

        var sDate = document.getElementById('start').value;
        var eDate = document.getElementById('end').value;

        $.ajax
             ({
                 url: "@Url.Action("MachineParameter","Machines")",
                 data: { startDate: sDate, endDate: eDate },
                 type: "POST",
                 success: function () {
                     alert(sDate);
                     $("#chart").kendoChart
                 ({
                     theme: $(document).data("kendoSkin") || "default",
                     title: {
                         text: "Pie Chart Test"
                     },
                     legend: {
                         position: "bottom",
                     },

                     dataSource:
                         {
                             transport:
                                 {
                                     read:
                                             {
                                                 url: "@Url.Action("MachineParameter", "Machines")",
                                                 dataType: "json",
                                                 contentType: 'application/json; charset=utf-8'
                                             }
                                 }
                         },

                     seriesDefaults: {
                         labels: {
                             visible: true,
                             format: "{0}"
                         }
                     },

                     series: [{
                         type: "pie",
                         field: "Duration",
                         categoryField: "MachineGroup"
                     }],

                     tooltip: {
                         visible: true,
                         format: "{0}"
                     }
                 });
                 }

             });
    }

You could access it via your Model or make an AJAX request to the Parameter action in your controller. I have rewrote your Parameter Action to return the View and use the MachinesSql as the model:

public ActionResult Parameter()
{
   MachinesSql model = new MachinesSql();

   return View("YourViewName", model);
}

Then in your view you could do:

@Model MachinesSql

foreach(var m in @Model.SqlAccessParameter(startDate, endDate)) {
    @Html.DisplayFor(m=>m.DataValue);
}

Edit: Showing how to achieve via an AJAX Call

function CallAjaxFunction() {
     var sDate = document.getElementById('start');
     var eDate = document.getElementById('end');

     $.ajax{({
         url: '@Url.Action("Parameter")',
         data: { startDate: sDate, endDate: eDate },
         type: "POST",
         success: function(content) { 
            alert(content);
         }
     }); 
}
