WP7 dragging a pushpin on a map

Does anyone have any insight into how to implement a draggable pushpin on a map on a WP7 client running Mango? I have a pushpin bound to a geo-location on a map and I want the user to be able to drag it on a map and record its new location. I've seen some resources, but they're for non-WP7 Bing Maps control. Any help would be appreciated.

Thanks!

Solution

  • e.GetPosition(element) gives the position relative to the element passed on the parameter. Also, the point to convert using ViewportPointToLocation has to be relative to the position of the map. So, you have to do the following: 

        Pushpin myPin = sender as Pushpin;
    Point p = e.GetPosition(**Map**);
    g = Map.ViewportPointToLocation(p);
