Micrsoft Dynamics CRM 2011 online - Retrieve Plugin

If  you want to write a plugin that executes every time a user opens a record.

Here is the Retrieve Code

First, create a new Plugin and sign the assembly with a key:

public void Execute(IServiceProvider serviceProvider)
    // Obtain the execution context from the service provider.
    Microsoft.Xrm.Sdk.IPluginExecutionContext context = (Microsoft.Xrm.Sdk.IPluginExecutionContext)

    if (context.Depth == 1)
        IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
        IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

        // Obtain the target entity from the input parmameters.
        EntityReference entity = (EntityReference)context.InputParameters["Target"];

        ColumnSet cols = new ColumnSet(
                             new String[] { "lastname", "firstname", "address1_name" });

        var contact = service.Retrieve("contact", entity.Id, cols);

        if (contact != null)
            if (contact.Attributes.Contains("address1_name") == false)
                Random rndgen = new Random();
                contact.Attributes.Add("address1_name", "first time value: " + rndgen.Next().ToString());
                contact["address1_name"] = "i already exist";

Next, got to the Plugin Registration Tool (included with the CRM SDK) and register the plugin as follows:


What you’ll end up with in this example is:
On first open of the record:
On all future opens of the record:
