[mapguide-users] Reloading runtime map

[Hidekazu Shimaji]

Hi,

You should use the MgMap object, not the SetResource function.
Like this:

--- code start
//open the run-time map
MgMap map = new MgMap();
map.Open(resourceService, "MapName"); //ex)showing "MapName.MapDefinition"
//create a MgLayer object from a new layer resource
MgResourceIdentifier newLayerId = new MgResourceIdentifier("Library://....LayerDefinition");
MgLayer layer = new MgLayer(newLayerId, resourceService);
layer.SetDisplayInLegend(true);
layer.SetLegendLabel("NewLayer");
layer.SetName("LayerName");
layer.SetSelectable(true);
layer.SetVisible(true);
layer.ForceRefresh();
//get a layer collection from the map, and add the new layer to a map
MgLayerCollection layers = map.GetLayers();
layers.Add(layer);
//save the map
map.Save(resourceService);
--- code end

Php code is available in "the Developer's Guide (PDF)".

You have to use a Refresh() javascript function after adding the layer.
