Bing Maps Polygon InfoBox

Question

I have setup a map with polygons around the countries on the map, and want to add an infobox so that on hover some information will be displayed for each country.

I can get infoboxes displaying easy enough without the polygons, but when assigning them to the PolygonOptions class, nothing happens. The docs say that so long as I have the Bing Themes module loaded (Which I do), the infoboxes will show up on hover and click.

There seems to be zero documentation/examples of this, so hoping you clever folks can help out.

Here is some of the relevant code;

    var center = this.map.getCenter();

    // Create an info box 
    var infoboxOptions = {
        width: 300,
        height: 100,
        title: 'Testing', // sourceItems.data.dataset[0].data[index].key,
        description: "Visits: 20", // + sourceItems.data.dataset[0].data[index].visits,
        showPointer: true,
        titleClickHandler: this.polygonInfo,
        offset: new Microsoft.Maps.Point(-100, 0),
        typeName: Microsoft.Maps.InfoboxType.mini,
        zIndex: 1000
    };
    var polyinfobox = new Microsoft.Maps.Infobox(center, infoboxOptions);

    var polygonOptions = {
        fillColor: Microsoft.Maps.Color.fromHex(fillColour),
        strokeColor: Microsoft.Maps.Color.fromHex(fillColour),
        strokeThickness: 1,
        infobox: polyinfobox
    };

    var result = new Microsoft.Maps.Polygon(vertices, polygonOptions);

There is a working code sample in the interactive SDK for the Bing Maps V7 control here: http://www.bingmapsportal.com/ISDK/AjaxV7#BingThemeModule6

Note that creating an infobox for each shape is very inefficient and will hurt performance if you have a lot of shapes. A better method is to have one infobox and dynamically populate it's data. I wrote a blog post on this here: http://rbrundritt.wordpress.com/2011/10/13/multiple-pushpins-and-infoboxes-in-bing-maps-v7/ If you want to use this approach here is a code sample:

                credentials: "YOUR_BING_MAPS_KEY"
            });

            dataLayer = new Microsoft.Maps.EntityCollection();
            map.entities.push(dataLayer);

            var infoboxLayer = new Microsoft.Maps.EntityCollection();

                infobox.setLocation(loc);

                var opt = e.target.Metadata;

                }
            }
        }
      </script>
   </head>
   <body onload="GetMap();">
      <div id='mapDiv' style="position:relative; width:600px; height:600px;"></div> 
   </body>
</html>

Ah legend, thank you. I had hacked together something similar by myself, but this is much cleaner. — PizzaTheHut, Sep 01 '14 at 08:01
