[mapguide-users] Get selected layers from server side

[Ivan Milicevic]

Try this J

 

MgSelection selection = new MgSelection(map);

      selection.Open(resourceService, "1"); //opens selection

 

      MgReadOnlyLayerCollection layers = selection.GetLayers(); //gets
layers from selection 

      MgLayerCollection zdenci = map.GetLayers();

I know there is always a way to submit a form via POST, but it can be an

unwieldy proces. I am interested to know if the MapGuide server can
supply a

list of selected layers to a server-side program.
