[mapguide-users] Selection Limit?

[Tom Lazo / Stygy]

Hi Nick,

Actually, there is a feature selection limit. Its name is
SelectionFilterSize and u can find it on 2 config files: 

- C:\Archivos de programa\MapGuideOpenSource2.0\Server\Bin\serverconfig.ini
- C:\Archivos de
programa\MapGuideOpenSource2.0\WebServerExtensions\www\webconfig.ini

Both on [GeneralProperties].

Just change that number and restart your services.

Hope it helps.

Tom
