Multiple Relationship Queries on a single QueryTask

HeatherMeadow

I am new to ArcGIS and I am trying to query related records for two separate tables on a single feature. My problem is that when a relationship query is executed, I do not know which relationship completed in the event handler. Is there a way to determine which relationship has been executed within the QueryTask_ExecuteRealtionshipQueryCompleted event? That is without having to hard code it and look for the exact attributes returned from the query.

Any help or solutions would be appreciated.

Thanks!

Sure, you can use UserToken to save any object that you want retrieved in the Completed event.

For example, from this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#QueryRelatedRecords, you can add the following code.

                           queryTask.ExecuteRelationshipQueryAsync(relationshipParameters, relationshipParameters);             }         }   void QueryTask_ExecuteRelationshipQueryCompleted(object sender, RelationshipEventArgs e)   {    var rp = e.UserState as RelationshipParameter;   }
