posted
I have a map with 4 layers: country, city, village, ...

the goal is that when the user clicks on a country, display city layer (centered in the country). When you click on a city, people look the village, centered in the city, ...

In addition, each layer must have a MapColorSwatchPane  or change the property LayerName of MapColorSwatchPane.

Example: The original map is the world. When you click on Europe, the map show the countries layer, with the map centered on Europe. When you click on Spain, the map sohw the layer of autonomous communities, centering the map in Spain, ...

    Hi jcsanchezr

    You can attach to XamMap's ElementClick event and then call XamMap's WindowFit method to adjust the window rectangle to fit the clicked element. E.g.:

    In XAML

    <Maps:XamMap x:Name="xamMap" ElementClick="xamMap_ElementClick">
     <Maps:XamMap.Layers>
      <Maps:MapLayer x:Name="worldLayer">
       <Maps:MapLayer.Reader>
        <Maps:ShapeFileReader Uri="ShapeFiles/world/world" DataMapping="Name=CNTRY_NAME; Caption=CNTRY_NAME; Value=POP_CNTRY" />
       </Maps:MapLayer.Reader>
      </Maps:MapLayer>

      <Maps:MapLayer VisibleFromScale="1.7" Brushes="#FF3969A5 #FF71A1DA" x:Name="statesLayer">
       <Maps:MapLayer.Reader>
        <Maps:ShapeFileReader Uri="ShapeFiles/usamap/states" DataMapping="Name=STATE; Caption=STATE" />
       </Maps:MapLayer.Reader>
      </Maps:MapLayer>            

     </Maps:XamMap.Layers>

     <Maps:MapNavigationPane HorizontalAlignment="Left" />

    </Maps:XamMap>

    Code behind:

    private void xamMap_ElementClick(object sender, MapElementClickEventArgs e)
    {
     xamMap.WindowFit(e.Element);
    }

    Please let me know if this works for you.
