Tim,

>If I set up a listener in the biz object to receive the data as needed are there methods to allow the biz object to notify the form of the new information.

There is--you can manually raise the StateChange event in the business object and the user interface controls can automatically bind to the data. For example:

this.CallStateChange(mmBusinessState.Bind, "MyTable");

>If I set up the listener in the form (seems wrong) then the form can update it's display but then the biz obj would have to get it's info from the form. (seems backwards).

Right...the business object should never access or even be aware of user interface controls.

Best Regards,
