    I am wondering if I could create a information layer which dynamically feeds information from external source such as the eartthquake from USGS.GOV web site, i.e. http://earthquake.usgs.gov/eqcenter/catalogs/eqs7day-age_src.kmz

    If so, could you send me a sample code?

    Hi MarieQB,

    Yes, you can use external source. You can load a file from internet using the WebClient class. The map control does not support kmz files directly, but you can use the following link to download the sharpziplib library:

    The sample code of loading kmz file is below.

    private void LoadKML(object sender, RoutedEventArgs e)
        WebClient client = new WebClient();
        client.OpenReadCompleted += new OpenReadCompletedEventHandler(client_OpenReadCompleted);
        client.OpenReadAsync(new Uri("http://earthquake.usgs.gov/eqcenter/catalogs/eqs7day-age_src.kmz"));

    void client_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
        ZipFile zipFile = new ZipFile(e.Result);

    List<FrameworkElement> list = KmlReader.Read(zipFile.GetInputStream(0));
        foreach (FrameworkElement element in list)

    Best wishes,

    Do you have support for displaying GeoRSS feeds?  If so, please throw a quick code sample (or link to one).

    Hi Michael,

    Presently, the map control has not the feature you requested. Also currently it is not in our plans. I will make sure it is reconsidered when discussing our future plans, but I am afraid no certain time frame can be given at the moment.

    All the best,

    I am getting started with the silverlight map.  Do you have a starter project I can use that is similar to your demo layout and theme?

    Hello shawn,

    The QSF is very complex application. I wouldn't recommend to use it as a starter project. The simple XAML code which uses the map control are below.
    <UserControl x:Class="RadMapStarter.MainPage"
        d:DesignHeight="300" d:DesignWidth="400">
        <Grid x:Name="LayoutRoot" Background="White">
            <telerik:RadMap x:Name="radMap"
                    <telerik:OpenStreetMapProvider />

    I have attached a sample solution. Just update the references to the three following DLLs:
    - Telerik.Windows.Controls.dll
    - Telerik.Windows.Controls.DataVisualization.dll
    - Telerik.Windows.Data.dll

    Also for more information I would recommend to take a look to the following help topic:
