How To Allow CRM Plugin To Handle Multiple Event Messages

Question

I need to create a single plugin to fire on create, update, and delete events of opportunity entities.

Can I do these in a single plugin? If so then how can I do them?

Answer 1

yes you can use same plugin to execute it on create,update and delete

write your plugin as follows..

    public void Execute(IServiceProvider serviceProvider)
    {
          IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
           IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
           IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

           if (context.MessageName == "Create") 
           {
             //write the logic what you want this plugin to do on Create
           }
           if (context.MessageName == "Update") 
           {
            //write the logic what you want this plugin to do on Update
           }
           if (context.MessageName == "Delete") 
           {
            //write the logic what you want this plugin to do on Delete
           }  
}

Register your plugin on Create,Update,Delete for Oppertunity Entity using Plugin registration tool

it should work
