Currently working with the MapGuide OpenSource 2.0 API and need to return a list of all the unique values for a property for a particular layer
I have the following code where featureReader is of type MgFeatureReader string propertyName = "Condition"; MgFeatureQueryOptions queryOptions = new MgFeatureQueryOptions(); featureReader = featService.SelectFeatures(resId, propertyName, queryOptions); However I get the error message "An exception occurred in FDO component. Item 'Condition' not found in collection. I've tried using a MgDataReader but am running into the same error message as above. MgFeatureAggregateOptions queryOptions = new MgFeatureAggregateOptions(); dataReader = featService.SelectAggregate(resId, propertyName, queryOptions); Many Thanks, Adnan -- View this message in context: http://www.nabble.com/Return-all-unique-values-for-a-property-for-a-particular-layer-tp17143206p17143206.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
