I'm trying to follow this sample (http://demos.telerik.com/silverlight/#Map/Shapefile/World)
when I run my code, the map doesn't show up, just a blue rect. shows up. what am I missing?

    <UserControl.Resources>
        <example:ShapefileViewModel x:Key="DataContext" Region="world"/>
    </UserControl.Resources>
    <Grid x:Name="LayoutRoot" Width="640" Height="480">
        <telerik:RadMap x:Name="RadMap1"

            <telerik:InformationLayer x:Name="InformationLayer">
                <telerik:InformationLayer.Reader>
                    <telerik:MapShapeReader Source="{Binding Source={StaticResource DataContext}, Path=ShapefileSourceUri}"
                                            DataSource="{Binding Source={StaticResource DataContext}, Path=ShapefileDataSourceUri}"
                                            ToolTipFormat="CNTRY_NAME" />
                </telerik:InformationLayer.Reader>
                <telerik:InformationLayer.ShapeFill>
                    <telerik:MapShapeFill Fill="#fff7de" Stroke="#5a6368" StrokeThickness="1" />
                </telerik:InformationLayer.ShapeFill>
                <telerik:InformationLayer.HighlightFill>
                    <telerik:MapShapeFill Fill="#f7e7bd" Stroke="#5a6368" StrokeThickness="1" />
                </telerik:InformationLayer.HighlightFill>
            </telerik:InformationLayer>
        </telerik:RadMap>
    </Grid>
</UserControl>

And, my ShapefileViewModel.cs is exactly same as the sample code provided..

the shapefiles were not in the correct location. After setting that right, it works. Thanks.
