Shapefile shows in preview, not in debug

[Wyatt]

Doing a very simple shapefile based map.  I can see the map in preview, but not when I debug.  shapefiles are in a folder called Shapes just off the project root.

  <telerik:RadMap HorizontalAlignment="Left" Center="40,-74" VerticalAlignment="Top" Height="500" Width="600">
            <telerik:RadMap.Provider>
                <telerik:EmptyProvider />
            </telerik:RadMap.Provider>
            <telerik:InformationLayer x:Name="informationLayer" >
                <telerik:InformationLayer.Reader>
                    <telerik:MapShapeReader x:Name="xShapReader"
                                            Source="pack://siteoforigin:,,,/Shapes/cb_2013_us_state_500k.shp" 
                                            DataSource="pack://siteoforigin:,,,/Shapes/cb_2013_us_state_500k.dbf" 
                                            PreviewReadCompleted="MapShapeReader_PreviewReadCompleted" />
                </telerik:InformationLayer.Reader>


                <telerik:InformationLayer.ShapeFill>
                    <telerik:MapShapeFill Fill="#FFF0D9" Stroke="#B1946D" StrokeThickness="1" />
                </telerik:InformationLayer.ShapeFill>
            </telerik:InformationLayer>
        </telerik:RadMap>

Hello Wyatt,

It is hard to say about particular causes of this problem without your solution, but using just a code snippet you sent. But it looks the properties of shp and dbf files in your project are incorrect. You should be sure that your shape-file is copied to the output directory:
1. Select the cb_2013_us_state_500k.shp and dbf in the solution explorer.
2. Go to the "Properties" window.
3. Check that "Build Action" is set to "None".
4. Check that "Copy to Output Directory" is set to "Copy always" or to "Copy if newer".

Also you can check an error which can occur during loading of shape-file. You can check the PreviewReadShapesCompletedEventArgs.Error property in your PreviewReadCompleted event handler. It returns the exception when an error occurs.
The sample code is below.

private void MapShapeReader_PreviewReadCompleted(object sender, PreviewReadShapesCompletedEventArgs eventArgs)
{
    if (eventArgs.Error != null)
    {
        MessageBox.Show(eventArgs.Error.Message);
    }
    else
    {
        // process items
        // eventArgs.Items contains the list of objects which are created by MapShapeReader
    }
}

I hope this information will be helpful.

Thank you for the reply.  There really isn't anything else to the code.
I made the changes you suggested and it  does return the following error, but it's pretty generic "An exception occured during a WebClient request".

Here is all the code. nothing in the .cs file except the exception cache you suggested.

the inner exception is "The URI prefix is not recognized."

resolved now.  I was using the properties window for the information layer to select the datasource and source. looks like it doesn't put in the right information for it to work.
