[mapguide-users] MapGuide Selection and UniqueID Determination

[Berdel, Brian]

I have a quick question about selection as well...If I have the
selection XML can I just call the Javascript Function setSelection, or
do I have to do the code in the code behind for it to work? Basically I
have tried itand it does display that a selection has been made in the
panel and the status bar, but the map is not updated, even after a
refresh...

-Thanks

Brian

To be able to select items the layer must be selectable (set in the 
MapDefinition).
Secondly, the FeatureSource must have at least one identity column.
If not, all features on the layer are selected.
