Question

I would like the user to add several pins to a map to represent tents or people using map1_Hold event.
How can I do this and store each dropped pin location on a cloud later(windows azure)?

Answer 1

To drop pins on a map you can do the following: (here map comes from my .xaml page where map is the name of the Map: <my:Map Name="map" ...

Setting up the event handler

map.Hold += new EventHandler<GestureEventArgs>(dropPin_Hold);

and the actual event handler:

void dropPin_Hold(object sender, GestureEventArgs e)
{
    // drop a pin at the Held location
    GeoCoordinate pinLocation = new GeoCoordinate();
    // gets the dropped position
    pinLocation = map.ViewportPointToLocation(e.GetPosition(map));

    newLocation = new Pushpin() { Location = pinLocation, Name = "Tent's name" Content = "new tent" };
    map.Children.Add(newLocation);

    // save the newLocation however you want

}

Multiple holds will result in multiple pins being displayed on the map.
