Where does the kml file loading process occur?

Hello, I'm still quite new with the ArcGIS SDK.

I'm loading a kml file into my application to display its content in a xaml treeview. And it works fine.

But unfortunately if the kml file is very large then my application freezes during the loading process.

That's why I decided to outsource the loading process into another thread. But I don't know where the loading process exactly occurs.

I open a file dialog and parse the content of the kml file into a kmlTree.

OpenFileDialog openFileDialog = new OpenFileDialog(); openFileDialog.Filter = "KML File|*.kml"; openFileDialog.Title = "Open KML file:"; Nullable<bool> dialogResult = openFileDialog.ShowDialog(); if (dialogResult == true) { string path = openFileDialog.FileName; Uri kmlUri = new Uri(path); Dataset = new KmlDataset(kmlUri); KmlLayer layer = new KmlLayer(Dataset); SavesTreeToLayer.Add(kmlTree, layer); mapView.Map.OperationalLayers.Add(layer); }

Does anybody have an idea?

Thanks in advance.

Hi,

Do you mean your loading process or ArcGIS Runtime parsing the KML contents?

Can you share any code?
