How to: Load Vector Data from a KML File

• Jul 26, 2018

To load vector data from a KML file, do the following.

• Create a VectorFileLayer object and add it to the MapControl.Layers collection.
• Create an instance of the KmlReader class and assign the instance to the VectorFileLayer.FileReader property.
• Create a MapFileSourceBase class descendant object, configure it and assign it to the MapFileReaderBase.FileSource property of the instance.

XAML

<Map:VectorFileLayer
    ShapeStroke="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Map:KmlReader>
        <Map:KmlReader.FileSource>
            <Map:MapPackageFileSource 
                FileName="Assets\States.kml"/>
        </Map:KmlReader.FileSource>
    </Map:KmlReader>
</Map:VectorFileLayer>
