Map - Prevent Panning Map off the screen

[Jim]

When running the demo of the wpf controls and running the map example "First Look". Its possible to pan the map right off the screen.
I have the same issue in my application and I need to stop this from happening.

I see this was a previous issue under Issue ID 3713 - Map: Ability to limit panning and zoom ranges.
This issue has the status of resolved but I don't see what the solution is.

I figured out how to limit zoom ok by using MinZoomLevel and MaxZoomLevel but I see nothing for limiting panning.

I still need a solution for panning?

Please help.

Thanks

Hello Jim,

You can use the GeoBounds property of RadMap for limiting panning. The sample following code restricts panning to whole world map:

public partial class MainWindow : Window

{

    public MainWindow()

    {

        InitializeComponent();


        var provider = new BingMapProvider(MapMode.Aerial, true, "My BingMap Key");

        this.radMap.InitializeCompleted += new EventHandler(radMap_InitializeCompleted);

        this.radMap.Provider = provider;

    }


    private void radMap_InitializeCompleted(object sender, EventArgs e)

    {

        this.radMap.GeoBounds = new LocationRect(new Location(this.radMap.SpatialReference.MinLatitude, this.radMap.SpatialReference.MinLongitude),

            new Location(this.radMap.SpatialReference.MaxLatitude, this.radMap.SpatialReference.MaxLongitude));

    }

}

All the best,
