- 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.datais undefined - and I'm guessing its should be justdata) – user3559349 Commented Dec 20, 2016 at 11:41

Reset to default 1Controller :-
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);
},
