If you are using the Silverlight Bing Map control for Windows Phone (or for the desktop for that matter) you have the ability to add a MapLayer where you can add you controls or images at specific latitudes and longitudes. You can really get creative and do some awesome things with a MapLayer.
Prior to SWFL Code Comp this year if I added a UIElement and needed to move it, I removed it from the original MapLayer and then added it back in at the new Lat & Lon where it should be displayed.
_drawLayer.AddChild(_myImage, position, PositionOrigin.Center);
Each time I did this I had to hold my nose ‘cause this had such a bad smell to it…there had to be a better way, but I was just too
busy, lazy, no I guess actually too busy to do the required research and this sort-of worked and a lot of other stuff didn’t.
After initially adding the UIElement to the MapLayer we can simply update the position with the following chunk of code.
Much cleaner eh?
