[mapserver-users] Unable to access Grid Object (GridObject) via C# MapScript interface (related to bug 1980)

[Tamas Szekeres]

Brian,

Which version are you using? I guess the mapserver 5.0 should contain
this option. Here's the related change, which is pretty old.

http://trac.osgeo.org/mapserver/changeset/6362

Best regards,

Tamas
