Thanks Graham,

I've a problem, I've used your code but in the Imported method, the foreach loop is empty (there are no elements).

This is my xaml:

<igMap:XamWebMap x:Name="map1" ElementClick="map1_ElementClick" >    

        <igMap:XamWebMap.Layers >

            <igMap:MapLayer x:Name="LayerItalia" DataMapping="Name=CountryName; Value=NAME_1" Loaded="map1_Loaded" Imported="map1_Imported">            

                <igMap:MapLayer.Reader>    

<igMap:ShapeFileReader Uri="Shapefiles/ITA_adm2" DataMapping="Name, Caption=NAME_2" >

                            <igMap:ShapeFileReader.CoordinateSystem>

                            <igMap:CoordinateSystem>

                                <igMap:CoordinateSystem.Projection>

                                    <igMap:SphericalMercator/>

                                </igMap:CoordinateSystem.Projection>

                            </igMap:CoordinateSystem>

                    </igMap:ShapeFileReader.CoordinateSystem>

                    </igMap:ShapeFileReader>

                </igMap:MapLayer.Reader>                

                </igMap:MapLayer>            

            </igMap:XamWebMap.Layers>

</igMap:XamWebMap>

Thanks

You can determine the outer bounds of the elements you want to display and set that to the window rect. For example, with the states sample if I call this on imported:

private void usaLayer_Imported(object sender, MapLayerImportEventArgs e)
        {
            double minY = double.MaxValue;
            double maxY = double.MinValue;
            double minX = double.MaxValue;
            double maxX = double.MinValue;

            foreach (MapElement ele in (sender as MapLayer).Elements)
            {
                if (ele.Name == "Iowa" || ele.Name == "Indiana")
                {
                    minY = Math.Min(minY, ele.WorldRect.Top);
                    maxY = Math.Max(maxY, ele.WorldRect.Bottom);
                    minX = Math.Min(minX, ele.WorldRect.Left);
                    maxX = Math.Max(maxX, ele.WorldRect.Right);
                }
            }

            if ((sender as MapLayer).Elements.Count > 0)
            {
                theMap.WindowRect = new Rect(minX, minY, maxX - minX, maxY - minY);
            }
        }

It will snap the screen to contain Iowa and Indiana.
