Hi Tim,
The scenario that you want to achieve will be similar to the one demonstrated here. When the client-side requestItems method is called a callback request is made, causing the ItemsRequested server event to fire or a request to be sent to a WebService. In your case you should not subscribe on the server-side event, but provide a service. On how to pass information to your service, which in your case will be the selected value of the first combobox, please refer to the following help article.
