[mapguide-users] set "filter applied to data" programmatically

[Kenneth Skovhede, GEOGRAF A/S]

Look at the buffer.* files in your MapGuide installation:
C:\Program 
Files\MapGuideOpenSource\WebExtensions\www\mapviewer(php|net|java)\buffer.(aspx|jsp|php).

If you are using .Net, you can also try the MaestroAPI:
http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI/samples/ModifyLayerFilter

The approach used in the MaestroAPI example is the same you would use
in the other languages.
