Change marker layer's data source

[Marc Arbesman]

Hello,

I am trying to set marks on a marker layer via JSON returned from my MVC controller.  I am capturing an onCriteriaChange event from a ListView.  In the event handler function I am try the following

var mapData = $('#map').data('kendoMap');
        mapData.layers[1].dataSource = new kendo.data.DataSource({
            transport: {
                read: {
                    url: ('@Url.Action("getMapData")'),
                    dataType: "json",
                    data: { customerId: customer.Id }
                }
            }
        });
        mapData.layers[1].dataSource.read();

My declaration code is 

$("#map").kendoMap({
                          center: [30.268107, -97.744821],
                          zoom: 15,
                          layers: [{
                              type: "tile",
                              urlTemplate: "http://#= subdomain #.tile2.opencyclemap.org/transport/#= zoom #/#= x #/#= y #.png",
                              subdomains: ["a", "b", "c"],
                              attribution: "© <a href='http://osm.org/copyright'>OpenStreetMap contributors</a>." +
                                           "Tiles courtesy of <a href='http://www.opencyclemap.org/'>Andy Allan</a>"
                          },
                          {
                              type: "marker",
                              locationField: "latlng",
                              titleField: "name",

                          }]
                      });

so you can see the layer already exists.  I just want to set a marker for the lat, long returned by my controller.  

I can verify that my controller is producing JSON (see attached screenshot).   But the markers do not show. Am I doing this correctly? Any help would be appreciated.

Hello,

The DataSource instance can't be replaced directly as there's no suitable setDataSource method.
We'll add such method for the next release, but in the meantime you can use the following workaround:
mapData.layers[1].options.dataSource = new kendo.data.DataSource({});
mapData.layers[1]._initDataSource();

Apologies for the caused inconvenience.
As a token of gratitude for your involvement your Telerik points have been updated.
