I have been able to set up and see both relationship class relates and relates within an MXD in the ArcGIS Services Directory. I have some functionality that works with the relationship class approach. With a relate set up in a MXD, queryDomainsTask.ExecuteRelationshipQueryAsync raises an error. Is there some difference in the RelationshipParameter requirements??
(I copied the ArcGIS Services Directory to an area below the code here. It shows the relationship with ID 1. When doing the query interactively -- on the Query Related Records page, a faint message states "relationshipID (1) not found").
{
...
RelationshipParameter relationshipParameters = new RelationshipParameter()
{
ObjectIds = (int[])ObjIds,
DefinitionExpression = exp,
OutFields = new string[] { "OBJECTID, scientific_name, TSN_genus, TSN_species, ITIS_hyperlink" },
RelationshipId = 1,
OutSpatialReference = MyMap.SpatialReference
};
Cursor = Cursors.Wait;
queryDomainsTask.ExecuteRelationshipQueryAsync(relationshipParameters);
}
