KML and Polygons

[John]

After searching through the great forums here and looking for an answer (and trying many different things), I am still stuck...sorry for the remedial question, but Silverlight and Telerik are both new to me!

I have 3 KML files that all contain multiple polygons that have styling performed on them, such as (stripped down version):

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
  <Document>
<name>Mapinfo Import</name>
  <Style id="polystyle">
    <LineStyle>
      <color>ff7faaff</color>
    </LineStyle>
    <PolyStyle>
      <fill>1</fill>
      <color>7fff0000</color>	
    </PolyStyle>
  </Style>
  <Style id="textstyle">
      <IconStyle>
        <Icon></Icon>
      </IconStyle>
      <LabelStyle>
        <color>ff0000ff</color>
      </LabelStyle>
    </Style>
<Placemark>
  <styleUrl>#polystyle</styleUrl>

I have a radMap control on my page along with 3 checkboxes that the user can select to load one of the three KML files, which reside in a subfolder called includes.

I am using the OpenStreetMap provider...

Here is the checked event for one of the checkboxes:

private void chkPhone_Checked(object sender, RoutedEventArgs e)
        {
 
                OpenStreetMapProvider provider = new OpenStreetMapProvider(MapMode.Aerial, true);
                //BingMapProvider provider = new BingMapProvider(MapMode.Aerial, true, applicationId);
                //ArcGISServerMapProvider provider = new ArcGISServerMapProvider(MapMode.Aerial, true);
                RadMap1.Provider = provider;
 
                RadMap1.Center = new Location(38.207034, -91.160209);
 
                // loading the kml file
                StreamResourceInfo streamInfo = Application.GetResourceStream(
                    new Uri("MapTest;component/includes/ILEC_PHONE.kml", UriKind.RelativeOrAbsolute));
                List<FrameworkElement> list = KmlReader.Read(streamInfo.Stream);
 
                //informationLayer.ItemsSource = list;
 
                foreach (FrameworkElement element in list)
                {
                    MapPolygon shape = element as MapPolygon;
                    if (shape != null)
                    {
                        shape.Fill = new SolidColorBrush(Color.FromArgb(99, 99, 0, 99));
                    }
                }
 
                foreach (FrameworkElement shape in list)
                {
                    this.informationLayer.Items.Add(shape);
                }
            
        }

For the life of me, I cannot get the polygons to display on the map when checking the checkbox!  I am sure I am overlooking something very simple.

The namespace of this page is MapTest.  I assume I am referencing the KML correctly...but am unsure.

Also, I set the build action of the KML files to Resource.

Any help will be greatly appreciated!  For the first time in a long time, development has become interesting and fun again!

Thanks!

Hi John,

I would recommend you to use the InitializeCompleted event of RadMap, because when initialization of the provider is incomplete then the information layer is not ready to show shapes.
It occurs after you assign the RadMap.Provider property and the provider completes its initialization.
I have attached a small example with displaying polygons from the KML-file using this event.

I hope it helps.

Kind regards,
