>I guess that I will have to do a work around like what you mentioned. The situation is that there are 10 different fields that I use for measurements, so I have 10 text boxes and corresponding labels. The problem is that there are 6 different types that use only certain measurement fields and they are not consistant about the order in which they appear. What I had done was to assign the controlsource, caption and visible properties based upon what the type is for each record. The problem is that for some of the measurements there needs to be code attached to the lostfocus event of the corresponding control.

Hi Derek,
You might want to delegate the LostFocus functionality to the containing form(Bridge pattern). Add a property to your control classes, cWhatAmI and set it to the type of record. Your form class gets a ControlLostFocus method. Have the LostFocus of your controls call the ControlLostFocus method of the parent form and pass the record type information (or a reference to self).
This approach will allow you to put most of the code in the form class.

HTH,
