How to get the attributes from the relational table by using identify?

[weiliang]

Within our map service, one layer has a related table (not join). I want to get the assocated information from this table when using identify. How can this be fulfilled?

BTW, it seems that ADF can fulfill this by using default setting. But I tried with silverlight API, I cannot retrive the related table attributes.

Thanks,

Wei

Support for querying related data will be available with ArcGIS Server v10 and the upcoming release of the Silverlight API.

Do you know if this would be available for the API JavaScript?

[DominiqueBroux]

Yes it's available with Javascrip API : see sample http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/fl_query_related.html

Thanks a lot for the fast answer!

Right now we are using only Map Services, but no Feature Services, and JavaScript API 1.6, using Identify Task.
Could we use this with Map Services (not necessary Feature Service), using identify task?
Is only available in JavaScript API 2.0?

Regards.

With ArcGIS Silverlight/WPF API v2.0, you can use QueryTask (similar to the JavaScript sample as Dominique cited below).

QueryTask qt = new QueryTask(featureLayer.Url);
qt.DisableClientCaching = true;
RelationshipParameter rp = new RelationshipParameter();
rp.ObjectIds = new int[] { objectId }; //object id from featureLayer
rp.OutFields = new string[] { "agree_with_incident" }; //fields from related table
rp.RelationshipId = relationshipId; //can be retrieved from featureLayer's LayerInfo.Relationships
qt.ExecuteRelationshipQueryCompleted += qt_ExecuteRelationshipQueryCompleted;
qt.ExecuteRelationshipQueryAsync(rp);
