Hi Pham,

I had a similar use case for one of our projects, I went about creating a bidirectional association. I associate the part to the product (Ex: Part1 is associated to Product1) and I created another association between product and part (Ex: Product1 is associated to Part1). I also segmented the associations into 2 different association groups.

Below is a quick sample of what you can do (will need some refinement):

associations.Add(new Association
                    {
                        Group = new AssociationGroup
                        {
                            Name = "ProductAssociation",
                            Description = "The product associated to the part",
                            SortOrder = 100
                        },
                        SortOrder = 100,
                        Source = partRef,
                        Target = variant.GetParentProducts().FirstOrDefault(),
                        Type = new AssociationType
                        {
                            Id = AssociationType.DefaultTypeId,
                            Description = string.Empty
                        }
                    });

                    associations.Add(new Association
                    {
                        Group = new AssociationGroup
                        {
                            Name = "PartAssociation",
                            Description = "The part associated to the product",
                            SortOrder = 100
                        },
                        SortOrder = 100,
                        Source = variant.GetParentProducts().FirstOrDefault(),
                        Target = partRef,
                        Type = new AssociationType
                        {
                            Id = AssociationType.DefaultTypeId,
                            Description = string.Empty
                        }
                    });
_associationRepository.Value.UpdateAssociations(associations);

And below is how it would look like under realted entries:

1. Adding a product as a related entry to a part:
2. Adding a part as a related entry to a product:

Hi Siddharth Gupta,

I also did same as you did before. But i wonder why episerver does not support api to get bidirectional association.

Thank for your suggestion,
