KML Custom Data

[DmitriyKolokolnikov]

Does KML Placemark support storing custom data? I tried using KmlPlacemark.Attributes[], but it didn't seem to have any effect. What am I doing wrong?

// Create a new KML document.
_kmlDocument = new KmlDocument() { Name = "Vehicle Path" };

// Create a KML dataset using the KML document.
_kmlDataset = new KmlDataset(_kmlDocument);

// Create the KML layer using the KML dataset.
_kmlLayer = new KmlLayer(_kmlDataset);

// Create a KmlGeometry 
KmlGeometry kmlGeometry = new KmlGeometry(location, KmlAltitudeMode.Absolute);

// Create a new placemark.
KmlPlacemark kmlPlacemark = new KmlPlacemark(kmlGeometry);

// Add a Attribute
kmlPlacemark.Attributes["speed"] = VehicleSpeed;

// Add the placemark to the KmlDocument.
_kmlDocument?.ChildNodes.Add(kmlPlacemark);

// Save a file
_kmlDocument?.SaveAsAsync("test.kmz");

We're actively working on this, and editing custom data is planned to be available in the next release.
In the current 200.5 release you can access the custom data (read-only) in KmlNode.ExtendedSchemaData and KmlNode.ExtendedNonSchemaData
