Examples

This sample code uses the TileSource class to create a map tile layer and adds the map layer to the map. For more information and the complete sample, see Adding Tile Overlays to the Map.

private void AddTileOverlay()
{

    // Create a new map layer to add the tile overlay to.
    tileLayer = new MapTileLayer();

    // The source of the overlay.
    TileSource tileSource = new TileSource();
    tileSource.UriFormat = "{UriScheme}://ecn.t0.tiles.virtualearth.net/tiles/r{quadkey}.jpeg?g=129&mkt=en-us&shading=hill&stl=H";

    // Add the tile overlay to the map layer
    tileLayer.TileSource=tileSource;

    // Add the map layer to the map
    if (!MapTileOverlay.Children.Contains(tileLayer))
    {
        MapTileOverlay.Children.Add(tileLayer);
    }
    tileLayer.Opacity = tileOpacity;
}

Private Sub AddTileOverlay()

    ' Creates a new map layer to add the tile overlay to.
    tileLayer = New MapTileLayer()

    ' The source of the overlay.
    Dim tileSource As New TileSource()
    tileSource.UriFormat = "{UriScheme}://ecn.t0.tiles.virtualearth.net/tiles/r{quadkey}.jpeg?g=129&mkt=en-us&shading=hill&stl=H"

    ' Adds the tile overlay to the map layer
    tileLayer.TileSource = tileSource

    ' Adds the map layer to the map
    If Not MapTileOverlay.Children.Contains(tileLayer) Then
        MapTileOverlay.Children.Add(tileLayer)
    End If
    tileLayer.Opacity = tileOpacity
End Sub
