Unable to see map

[Jeremy]

Hello-

I am trying to display the RadMap, but when executed, the map isnt being displayed, just the background.  It's like the shapefile & dbf arent being loaded properly.  I've tried setting the Source and DataSource a few different ways and none seem to work.  I have the shp & dbf files located in a folder called Resources at the root of my project.  Below is a section of my xaml.  Any advice?

Thanks!
Jeremy

I'm having a similar issue.  When I run my project I get the following error:

System.FormatException

        </telerik:InformationLayer.HighlightFill>
    </telerik:InformationLayer>
</telerik:RadMap>

My shape files are also located in a folder at the root level of my TexasMap Silverlight application. I downloaded the files from the NGS Archive Shapefile website.

I fixed it!  For me, it was a matter of 2 things: 1) the project is DynamicsMaps, not DynamicMap.  The second, I needed to change the shp and dbf files' build action to Resource.  After that, they were there.

I hope this helps you too, Lyndsay.  Good luck!

Thanks for sharing. I had already set the build action to "Resource" with no luck. I'm using Rad Controls for Silverlight Q3 SP1 and this is the error I get:

Hello Jeremy Tucker,

First of all you should be sure that your files are included to your project as Resource:
1. Select world.shp and world.dbf in the solution explorer.
2. Go to the "Properties" window.
3. Check that "Build Action" set to "Resource".

Also you can check that the shapes have been read successfully.
The MapShapeReader contains the PreviewReadCompleted and ReadCompleted events. You can use one of them to check error if it occurs during the reading.
The sample code is below.

<telerik:MapShapeReader Source="/DynamicsMap;component/Resources/world.shp" DataSource="/DynamicsMap;component/Resources/world.dbf" ToolTipFormat="CNTRY_NAME" PreviewReadCompleted="MapShapeReader_PreviewReadCompleted"/>
</telerik:InformationLayer.Reader >

private void MapShapeReader_PreviewReadCompleted(object sender, PreviewReadShapesCompletedEventArgs eventArgs)
{
    if (eventArgs.Error != null)
    {
        // eventArgs.Error.Message contains information about error
    }
}

Hi Andrey,

I am facing similar issues with the map control. I checked the shape files are included as resource files. 
Also I am able to see the number of shapes inside the shape files. There is no error while loading the files. 
But still I am unable to load the map. 

<telerik:RadMap x:Name="radMap"
UseDefaultLayout="False"
                        Grid.Row="1"
                        Grid.Column="0"
                        Center="200,200"
ZoomLevel="13"
                        Width="784"
                        Height="484">
            <telerik:RadMap.Provider>
                <telerik:EmptyProvider MinZoomLevel="1" MaxZoomLevel="13" />
            </telerik:RadMap.Provider>
            <telerik:InformationLayer x:Name="informationLayer">
                <telerik:InformationLayer.Reader>
                    <telerik:MapShapeReader ClearLayer="True" 
                                            PreviewReadCompleted="MapShapeReader_PreviewReadCompleted"
                                            Source="/TestingMap;component/ShapeFiles/18Feb11/Brighton.shp">
                    </telerik:MapShapeReader>
                </telerik:InformationLayer.Reader>
            </telerik:InformationLayer>
        </telerik:RadMap>

        private void MapShapeReader_PreviewReadCompleted(object sender, PreviewReadShapesCompletedEventArgs eventArgs)
        {
// No error is getting caught at this point. 
            if (eventArgs.Error != null)
            {

            }

}

Only thing that I observe is the MapPolygon object does not have height and width. 

Error thrown at design time is 
System.InvalidOperationException
An unhandled exception was encountered while trying to render the current silverlight project on the design surface. To diagnose this failure, please try to run the project in a regular browser using the silverlight developer runtime.

Hi Lyndsay,

Currently the map control supports Mercator projection with real world's geographic coordinates in degrees only (-85/85 latitude and -180/180 longitude). It is known as WGS 84 or EPSG:4326.
I'm not sure what a coordinate system is used in your shape file, but it should be converted to EPSG:4326 before using with the map control.

Kind regards,

Hi,

when I'm trying to call: ShapeFileReader.Read(shpfile, dbffile)
I get FormatException:
"Input string was not in a correct format."
The details says: "When converting a string to Datetime, parse the string to take the date before putting each variable into the DateTime object."

It seems is a parsing issue. Can you suggest solution pls?

Thanks a lot.

[Andrey]

Hello Shawn,

You can specify your own set of properties including a type of each property which should be read by the ShapeFileReader. So, you can specify the date-time field as the property of the string type.
You don't need to specify all DBF fields. You can specify only the fields which are required in your application.
The sample code is below.

ExtendedPropertySet properties = new ExtendedPropertySet();
properties.RegisterProperty("Field #1", "Field #1", typeof(string), string.Empty);
properties.RegisterProperty("Field #2", "Field #2", typeof(string), string.Empty);

List<FrameworkElement> shapes = ShapeFileReader.Read(shpfile, dbffile, properties);
