Hi,
Thanks .its working fine now.
To build a map, you must have all the components:
1. FeatureSource, references data
2. LayerDefinition, references a FeatureSource
3. MapDefinition, references multiple LayerDefinitions
4. WebLayout, references a MapDefinition
All these items must be in a repository (either Library or Session)
I know the procedure to create it in mapguide maestro.
1) Now my problem was i want to create ALL the above items
programmetically (my input is only a shape file) byusing maestro dll.
If u know this plz help me
Regards,
Padmini.
