[mapguide-users] Update legend information on runtime

[dan.nilsson]

Hi!
I am using MapGuide version 3.1.0.9064 on a computer with Windows 10
Enterprise and IIS.
Using Application definition (Fusion layout), with slate index.html
I have a map with 864 layers on the map.
I have made shortcut functions to turn of and on layers and layergroups on
runtime:

Example:
InitializeWebTier();
userInfo = new MgUserInformation(mgSessionId);
siteConnection = new MgSiteConnection();
siteConnection.Open(userInfo);
MgMap map = new MgMap(siteConnection);
map.Open(resourceService, mgMapName);
laygroup = GetLayerGroupByName(map, "mylayergroupname");
setLayerGroupVisible(laygroup, false);
lay = GetLayerByName(map, "mylayername");
setLayerVisible(lay, false);
map.Save();
map.Dispose();

The map is updated when I have run the code and run map.redraw(); in
javascript. But I also want to update the legend so the user know what
layergroups and layers have been turned on or off, so then I run
map.reloadMap(); in javascript. First time I do this it works fine, but if I
run the shortcut to change layer settings with som other layers turned on,
and run map.reloadMap(); nothing happends on the legend. The map show the
changed information after map.redraw(); so that works fine.
What am I doing wrong? Why is it only possible to run map.reloadMap(); once
for me?
Is there a better call to refresh the legend, I think map.reloadMap(); is a
real performance killer?
I have searched information about this, but the only function I have found
to update the legend is map.reloadMap();.

//Dan
