Show relates from destination layer/table

Hi all,

i need to know by arcobjects which other layers/tables are related throught relationship classes or throught relates to an other.

For relationship classes there are no problems.

For relates, if I query the origin layer is ok, but if i query the destination layer, the relate has not shown.

Here a little code example:

ILayer lay=ArcMap.Document.SelectedLayer;

IRelationshipClassCollection relClasses = lay as IRelationshipClassCollection;

IFeatureClass fc = ((IFeatureLayer)lay).FeatureClass;

IEnumRelationshipClass enumRelC=relClasses.RelationshipClasses;

enumRelC.Reset();

IRelationshipClass relC = enumRelC.Next() as IRelationshipClass;

if (relC == null)

{

MessageBox.Show("NoRel");

return;

}

while (relC != null)

{

MessageBox.Show(relC.OriginClass.AliasName + " "+ relC.DestinationClass.AliasName);

relC = enumRelC.Next() as IRelationshipClass;

}

So, if the selected layer is the origin for relate, "OriginLay DestinationLay" has shown, if the selected is destination one, "NoRel" has shown instead.

Could you help me?

Thanks!

Fabiano
