Example

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 =
        (CreateOneToManyResponse)_serviceProxy.Execute(
        createOneToManyRelationshipRequest);

    _oneToManyRelationshipId =
        createOneToManyRelationshipResponse.RelationshipId;
    _oneToManyRelationshipName = 
        createOneToManyRelationshipRequest.OneToManyRelationship.SchemaName;

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

Dim eligibleCreateOneToManyRelationship As Boolean =
 Me.EligibleCreateOneToManyRelationship("account", "campaign")

If eligibleCreateOneToManyRelationship Then
 Dim createOneToManyRelationshipRequest As CreateOneToManyRequest =
  New CreateOneToManyRequest With {
   .OneToManyRelationship = New OneToManyRelationshipMetadata With {
    .ReferencedEntity = "account",
    .ReferencingEntity = "campaign",
    .SchemaName = "new_account_campaign",
    .AssociatedMenuConfiguration =
    New AssociatedMenuConfiguration With {
     .Behavior = AssociatedMenuBehavior.UseLabel,
     .Group = AssociatedMenuGroup.Details,
     .Label = New Label("Account", 1033),
     .Order = 10000},
    .CascadeConfiguration =
    New CascadeConfiguration With {
     .Assign = CascadeType.NoCascade,
     .Delete = CascadeType.RemoveLink,
     .Merge = CascadeType.NoCascade,

   },
   .Lookup = New LookupAttributeMetadata With {
    .SchemaName = "new_parent_accountid",
    .DisplayName = New Label("Account Lookup", 1033),
    .RequiredLevel = New AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
    .Description = New Label("Sample Lookup", 1033)
   }
  }


 Dim createOneToManyRelationshipResponse As CreateOneToManyResponse =
  CType(_serviceProxy.Execute(createOneToManyRelationshipRequest), CreateOneToManyResponse)

 _oneToManyRelationshipId = createOneToManyRelationshipResponse.RelationshipId
 _oneToManyRelationshipName = createOneToManyRelationshipRequest.OneToManyRelationship.SchemaName

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