** The following was created before Map Suite 10. Map Suite 10 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility.  The majority of previously built code should work without modification assuming the new namespaces are added.  For guidance on upgrading your existing code check out this wiki article.  http://wiki.thinkgeo.com/wiki/map_suite_10_upgrade_guide

=====Version 3.1.16=====
Release date: 2/6/2009

ThinkGeo.MapSuite.Web Namespace:
  * Added new feature: Draggable markers.
  * Resolved issue with zooming out after doing a postback.

  *   * Draggable markers:  *   * 

{{webedition:Draggable markers sample.jpg}}

{{webedition:Draggable markers diagram.jpg}}

The code to implement a draggable marker is quite simple. An example:
<code csharp>
  SimpleMarkerOverlay markerOverlay = new SimpleMarkerOverlay("MarkerOverlay");
  markerOverlay.DragMode = MarkerDragMode.Drag;
  markerOverlay.Markers.Add(new Marker(0, 0, new WebImage(21, 25, -10.5f, -25f)));
  Map1.CustomOverlays.Add(markerOverlay);
