Number formatting

For numbers, the formatting settings required to apply through code behind are:

    ViewBag.DataSource = data;
    return View();
}

Limitations of date formatting

As per Firefox and Edge browsers standards, most of the date and time formats used in data source aren’t supported. For example: Apr-2000, Apr-01-2000, 01-03-2000, 2000-Apr-01 etc… are not supported. Meanwhile ISO formats will be supported across all browsers.
