[Solved] RadMap Goes Blank When Shapefile is used as Source

[Jacques]

Hi there,

I'm using the RadMap control along with a Shapefile. We're loading a background image into the Silverlight grid background property which shows fine. But then when I set the source to the shapefile and the datasource to the dbf file, the screen goes blank.

I've tried this declaratively 

<telerik:RadMap x:Name="MyMap" HorizontalAlignment="Stretch" Margin="0" VerticalAlignment="Stretch" Background="Transparent">
    <telerik:MapProviderCollection>
        <telerik:EmptyProvider />
    </telerik:MapProviderCollection>
    <telerik:InformationLayer x:Name="RadMapInformationLayer">
        <telerik:MapShapeReader DataSource="/TestMap.Floorplan;component/Images/One2OneScale.dbf"
                Source="/TestMap.Floorplan;component/Images/One2OneScale.shp" ClearLayer="False" />
    </telerik:InformationLayer>
</telerik:RadMap>

and using C# using the InformationLayer items collection,

StreamResourceInfo shapeResourceInfo = Application.GetResourceStream(new Uri("/TestMap.Floorplan;component/Images/One2OneScale.shp", UriKind.RelativeOrAbsolute));
StreamResourceInfo dbfResourceInfo = Application.GetResourceStream(new Uri("/TestMap.Floorplan;component/Images/One2OneScale.dbf", UriKind.RelativeOrAbsolute));

List<FrameworkElement> shapes = ShapeFileReader.Read(shapeResourceInfo.Stream, dbfResourceInfo.Stream);

foreach (var shape in shapes)
{
    RadMapInformationLayer.Items.Add(shape);
}

both result in the screen going blank (i.e. even the navigation elements of RadMap disappear).

The shapefile is set to use EPSG:4326 - WGS 84 for its CRS and I drew a simply polygon at a scale of 1:1. It's a single shape, nothing complex.

Any help would be appreciated.

Regards,
Jacques

Hello Jacques,
 
It is hard to say what is wrong with your application without your shape file. Please, open formal support (not Forum) ticket and attach your runnable solution so we could check what is wrong.

hi,Andrey
I also got the same problem which is the applicaiton shows blank after I add the .shp file
here is my xaml code:
<Grid>
            <telerik:RadMap x:Name="radMap"
Center="0.00566482542974434,-0.00197817993118133"
ZoomLevel="17"
MouseClickMode="None"
UseDefaultLayout="False"
UseSpringAnimations="False"
                        Background="Transparent"
                        IsMouseWheelZoomEnabled="True"
                        MouseDragMode="Select"
                        MouseDoubleClickMode="Center">
                <telerik:RadMap.Provider>
                    <telerik:EmptyProvider />
                </telerik:RadMap.Provider>
                <telerik:InformationLayer x:Name="informationLayer">
                    <telerik:InformationLayer.ShapeFill>
                        <telerik:MapShapeFill Fill="#feee" Stroke="White" StrokeThickness="1" />
                    </telerik:InformationLayer.ShapeFill>
                    <telerik:InformationLayer.Reader>
                        <telerik:MapShapeReader ClearLayer="False"
                                           
                                            ReadCompleted="MapShapeReader_ReadCompleted"
                                            DataSource="/campus_floorplan;component/ShapeFile/level4_d_pol.dbf"
                                            Source="/campus_floorplan;component/ShapeFile/level4_d_pol.shp">
                        </telerik:MapShapeReader>
                    </telerik:InformationLayer.Reader>
                </telerik:InformationLayer>
            </telerik:RadMap>
        </Grid>
cs:
 public MainWindow()
        {
            InitializeComponent();
            EmptyProvider provider = new EmptyProvider();
            this.radMap.Provider = provider;
}

Sometimes the { DataSource="/campus_floorplan;component/ShapeFile/level4_d_pol.dbf"
                                            Source="/campus_floorplan;component/ShapeFile/level4_d_pol.shp"} will have the red line to say that "the file is not the part of this project"
Is anything wrong about this source?
or is my .shp is not correct?
urgency hopely to be solved

Hi Zi,

First of all, check that "Build Action" for all these files is set to "Resource". If it doesn't help, please, open a formal support (not Forum) ticket and attach your runnable solution so we could check what is wrong.
