[mapguide-users] Re: Is it Possible to set Feature Label for a layer dynamically

[Kenneth Skovhede, GEOGRAF A/S]

If you look at the second link (to the documentation),
the method "SetLayerDefinition" can make the layer point to another 
resource.

As with the first example, you need to make a copy of the 
LayerDefinition xml.
If you just modify the LayerDefinition xml without making a copy, the change
will be visible for all users, current and future.

Basic steps are:
1) Obtain the MgMap instance
2) Find the layer
3) Load the LayerDefinition xml (link 1)
4) Modify the FeatureLabel (link 1)
5) Save a copy of the LayerDefinition xml (link 1)
6) Make the layer from step 2 point to the copy of the LayerDefinition 
from step 5 (link 2)
7) Save the MgMap instance from step 1
8) Refresh the map on the client (developer guide)

steps 1,2 and 7 have hints in the developer guide, but are
also avalible in the API documentation under MgMap.
