CreateOneToManyRequest Class

Contains the data that is needed to create a new One-to-Many (1:N) entity relationship.

Namespace: Microsoft.Xrm.Sdk.Messages
Assembly: Microsoft.Xrm.Sdk (in Microsoft.Xrm.Sdk.dll)

The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. For the complete sample, see the link later in this topic. This sample creates an entity relationship between Account and Campaign entities by using CreateOneToManyRequest.

bool eligibleCreateOneToManyRelationship =
    EligibleCreateOneToManyRelationship("account", "campaign");

if (eligibleCreateOneToManyRelationship)
    CreateOneToManyRequest createOneToManyRelationshipRequest =
        new CreateOneToManyRequest
        OneToManyRelationship =
        new OneToManyRelationshipMetadata
            ReferencedEntity = "account",
            ReferencingEntity = "campaign",
            SchemaName = "new_account_campaign",
            AssociatedMenuConfiguration = new AssociatedMenuConfiguration
                Behavior = AssociatedMenuBehavior.UseLabel,
                Group = AssociatedMenuGroup.Details,
                Label = new Label("Account", 1033),
                Order = 10000
            CascadeConfiguration = new CascadeConfiguration
                Assign = CascadeType.NoCascade,
                Delete = CascadeType.RemoveLink,
                Merge = CascadeType.NoCascade,
                Reparent = CascadeType.NoCascade,
                Share = CascadeType.NoCascade,
                Unshare = CascadeType.NoCascade
        Lookup = new LookupAttributeMetadata
            SchemaName = "new_parent_accountid",
            DisplayName = new Label("Account Lookup", 1033),
            RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
            Description = new Label("Sample Lookup", 1033)

    CreateOneToManyResponse createOneToManyRelationshipResponse =

    _oneToManyRelationshipId =
    _oneToManyRelationshipName = 

        "The one-to-many relationship has been created between {0} and {1}.",
        "account", "campaign");
