Bing Maps API - Deleting Contacts

I have a selection box that allows the user to switch between different lists that fill the bing map with points.

However, when they select another place from the list, I need to delete the old contacts before drawing new ones.

Any ideas, API docs don't seem to cover it?

To remove a single button (or any other kind of entity) from the map, you need to call the remove () method on the collection of objects containing the output: http://msdn.microsoft.com/en-us/library/gg427616.aspx . Or, if you want to reference the object by index, use removeAt () instead.

To clear all objects from the collection, call the clear () method.

Just to clarify the situation. Put it in order for me to figure it out.

Create a pushpin in JavaScipt:

var thisPin; var location new Microsoft.Maps.Location(YourLatitude, Your.longitude); thisPin = new Microsoft.Maps.Pushpin(location, { icon: 'path to image', anchor: new Microsoft.Maps.Point(YourOffsetX, YourOffsetY) }); map.entities.push(thisPin);

To remove the output, you still need to have thisPin pointer pointing to this particular output.

 map.entities.remove(thisPin);

This method is not well documented in the examples.
