Hello Adrian,

Thank you for your question.

I am glad to see that you are looking at our "Bind to JSON" sample.

If you want to get your data from some external source or MVC controller for example, you can use ajax calls like:

$.ajax({
  type: 'get',
  dataType: 'json',
  cache: false,
  url: '/MyController/MyMethod',
  data: { keyid: 1, newval: 10 },
  success: function (response, textStatus, jqXHR) {
    alert(parseInt(response.oldval + ' changed to ' + newval));                                   
  }
});

[HttpGet]
public ActionResult MyMethod(int keyid, int newval)
{
 ....
    return Json(new { success = true, oldval = oldval},
                JsonRequestBehavior.AllowGet);
}

Or you can use getJSON:

$.getJSON('http://example/functions.php', { get_param: 'value' }, function(data) {
    $.each(data, function(index, element) {
        $('body').append($('

            text: element.name
        }));
    });
});

Once the JSON is received you can set it as "dataSource" to your tileManager.

Let me know if I can be of further assistance.
