• Please check null values for json data – keerti Commented Dec 20, 2016 at 11:40
• Show your controller method (the error is almost certainly because data.data is undefined - and I'm guessing its should be just data) – user3559349 Commented Dec 20, 2016 at 11:41

Controller :-

private static readonly string connectionString =  ConfigurationManager.ConnectionStrings["ConnStringDb1"].ConnectionString;
        public ActionResult GetUser()
        {
            return View();

Your problem is this selector: $('#tblProducts tbody')

You have no table with that ID.

Changing it to $('.tblProducts tbody') or renaming your table to <table id="tblProducts"> should do the trick.

As a suggestion, move the DOM manipulation outside the loop, it will have better performance:

success: function (data) {
    var rows;
    $.each(data, function (i, item) {
        rows += "<tr>"
                  + "<td>" + item.EmpID + "</td>"
                  + "<td>" + item.EmpName + "</td>"
                  + "<td>" + item.Age + "</td>"
                  + "<td>" + item.Salary + "</td>"
             + "</tr>";
    });
    $('#tblProducts tbody').append(rows);
 },

I have established the connection to database and i want to display all the details in the db in the view in the table format but am unable to do it as my new can any one help.

 public class EmployeeModel

• Please check null values for json data – keerti Commented Dec 20, 2016 at 11:40
• Show your controller method (the error is almost certainly because data.data is undefined - and I'm guessing its should be just data) – user3559349 Commented Dec 20, 2016 at 11:41

Controller :-

private static readonly string connectionString =  ConfigurationManager.ConnectionStrings["ConnStringDb1"].ConnectionString;
        public ActionResult GetUser()
        {
            return View();
        }

        public JsonResult GetAllUser()
        {
            List<EmployeeModel> employee = new List<EmployeeModel>();
            string query = string.Format("Select * From Employee");
            SqlConnection connection = new SqlConnection(connectionString);
            {
                using (SqlCommand cmd = new SqlCommand(query, connection))
                {
                    connection.Open();
                    SqlDataReader reader = cmd.ExecuteReader();

                    while (reader.Read())
                    {
                        employee.Add(
                            new EmployeeModel
                            {
                                EmpId = int.Parse(reader["EmpId"].ToString()),
                                EmpName = reader.GetValue(0).ToString(),
                                Age = int.Parse(reader["Age"].ToString()),
                                Salary = int.Parse(reader["Salary"].ToString())
                            }
                        );
                    }
                }
                return Json(employee, JsonRequestBehavior.AllowGet);
            }
        }

View:

function GetEmployeeUsingAjax() {           
        $.ajax({
            type: 'GET',
            url: '@Url.Action("GetAllUser")',
            data: { },
            dataType: 'json',
            success: function (data) {
    var rows;
    $.each(data, function (i, item) {
        rows += "<tr>"
                  + "<td>" + item.EmpID + "</td>"
                  + "<td>" + item.EmpName + "</td>"
                  + "<td>" + item.Age + "</td>"
                  + "<td>" + item.Salary + "</td>"
             + "</tr>";
    });
    $('#tblProducts tbody').append(rows);
 },
            error: function (emp) {
                alert('error');
            }
        });
    }
</script>
<table id="tblProducts">
    <thead>
        <tr class="headings" style="background-color:#4495d1;">
            <th>EmpId</th>
            <th>EmpName</th>
            <th>Age</th>
            <th>Salary</th>
         </tr>
</thead>
    <tbody >
    </tbody>
</table>

Your problem is this selector: $('#tblProducts tbody')

You have no table with that ID.

Changing it to $('.tblProducts tbody') or renaming your table to <table id="tblProducts"> should do the trick.

As a suggestion, move the DOM manipulation outside the loop, it will have better performance:

success: function (data) {
    var rows;
    $.each(data, function (i, item) {
        rows += "<tr>"
                  + "<td>" + item.EmpID + "</td>"
                  + "<td>" + item.EmpName + "</td>"
                  + "<td>" + item.Age + "</td>"
                  + "<td>" + item.Salary + "</td>"
             + "</tr>";
    });
    $('#tblProducts tbody').append(rows);
 },
