If you use a timer, your data will be delayed by up to the period of the timer (e.g. if your timer fires every 5 seconds then there will be a delay of up to 5 seconds to display your data).
Rather than an infinite while or for loop, you can "loop" by having the RPC call's AsyncCallback onSuccess and onFailure methods make the RPC call again. On the server side, you can make the RPC call block until some data is ready. (You don't want to block for too long, otherwise the RPC call will time out--but not too short either, otherwise you will be creating unnecessary network traffic).
