Sample: Associate and Disassociate Records Using the REST Endpoint with Silverlight
[Applies to: Microsoft Dynamics CRM 2011]
This sample code is for Microsoft Dynamics CRM 2011, and can be found in the following location in the SDK download:
SDK/SampleCode/CS/Silverlight/CrmAssociateDisassociateSilverlight
If you just want to see how this sample works you can install (import) the AssociatedDisassociateSilverlightSample_1_0_0_0_managed.zip managed solution included in the download files. If you install this managed solution and want to create the web resources using the names below, your solution publisher customization prefix cannot be “sample” unless you uninstall (delete) the managed solution.
Requirements
For this sample to work two web resources will be created by using the following names and the content:
- sample_/CrmAssociateDisassociateSilverlightTestPage.html
An HTML page can be used to view the Silverlight control outside a form. The only purpose of this web resource is to provide the URL of the server when the Microsoft Silverlight control cannot access it itself through the Xrm.Page.context.getServerUrl when the Silverlight web resource is added in an entity form.
- sample_/Clientbin/CrmAssociateDisassociateSilverlight.xap
The name of this web resource just reflects the relative output location of the .xap file in the Microsoft Visual Studio 2010 Silverlight application (version 4) project.
Note
The customization prefix ‘sample_’ is not used in code. These samples will work using the customization prefix from any publisher. However the relative path of the simulated Scripts folder must be included in the name of the web resources.
Demonstrates
This sample provides the following:
Shows how to perform associate and disassociate operations using the REST endpoint and Silverlight.
When you preview the sample_/CrmAssociateDisassociateSilverlightTestPage.html web resource, you have two options:
Show Associating two Accounts
Show Associations using ActivityParty
If you choose Show Associating two Accounts, two accounts will be created and associated with one of the accounts set as the parent account. You will be prompted to disassociate and delete the accounts. If you choose not to disassociate and delete the accounts, the following output is displayed. You have the opportunity to open the account record that is associated to the other account.
Created Account named “AssociateDisassociateExample1 6/8/2011 2:29:47 PM”
with AccountId =”9EA099DB-BFD6-4495-9526-8620B5EF6A0D” for testing.
Created Account named “AssociateDisassociateExample2 6/8/2011 2:29:47 PM”
with AccountId =”D32B9BC5-9653-46C3-A9F0-AA265CC1DCC7” for testing.
Account named “AssociateDisassociateExample1 6/8/2011 2:29:47 PM” (9EA099DB-BFD6-4495-9526-8620B5EF6A0D)
is now the parent of AssociateDisassociateExample2 6/8/2011 2:29:47 PM (D32B9BC5-9653-46C3-A9F0-AA265CC1DCC7)
You decided not to delete the records.
View them here.
If you choose Show Associations using ActivityParty, an account and email record will be created and associated with the account set as an ActivityParty in the From field of the email. You will be prompted to disassociate and delete the records. If you choose not to disassociate and delete the records, the following output is displayed. You have the opportunity to open the email record to view the associated account.
Created Account named “ActivityPartyAssociateExample 6/8/2011 2:39:37 PM”
with AccountId =”65D7E730-6957-44B4-8265-2808A794A3C9” for testing.
Created Email with subject “ActivityPartyAssociateExample 6/8/2011 2:39:37 PM”
with ActivityId =”CE7E3D02-D39F-472B-8E46-DA0F946B65B1” for testing.
Created Activity party; the Account and Email are now related
You decided not to delete the records.

Preliminary Steps
This Silverlight application uses a service reference named CrmODataService that is added by using the steps detailed under Generating WCF Data Services Client Data Service Classes. The name of the System.Data.Services.Client context is ‘AdventureWorksCycleContext’ because the name of the organization was AdventureWorksCycle.
sample_/CrmAssociateDisassociateSilverlightTestPage.html
The following sample is the HTML file that is produced when you create a Visual Studio 2010 Silverlight Application (version 4) project named ‘CrmAssociateDisassociateSilverlight’ and select to include a website with it. Only three lines have been modified:
The #silverlightControlHost style width is set to 100%
The script reference to the Silverlight.js file is commented out (or removed). This will be provided by Microsoft Dynamics CRM.
A script reference to ../ClientGlobalContext.js.aspx was added. This provides access to a context object that is access from the code within MainPage.xaml.cs.
