[mapguide-users] Get the key field of ODBC table

[miansi]

Hello Jackie,

I stuggled presenting information from SQL 2008 View with JOINs and being
able to select features on the map. Looks like it is because of missing
Identity property (please see Brent's response):

http://n2.nabble.com/SQL-2008.-View-with-JOINS.-Not-able-to-select-features-on-the-layer.-tp2356197p2396390.html

I wonder if is there a way to override Identity property programmatically?
Can you help me on that one?

I am creating Layers and updating Map through xml already. So, I was
thinking if it is possible to reset Identity attribute for the FeatureSource
before I will create my Layer and update Map in code?


Thank you,

Andrei
