I need to do some calculations on a range of data in a table or Query. e.g. Variations, Sum, Average, ... I already made a component for this. Now, I want to make this component aware when the range of this table or Query changes. I know that you can be notified with the OnDataChange event. But I use First, Next for browsing through the range and make the calculations. So this isn't possible to use. Is there a way to be only notified when the range of the table or query changes? Or are there other functions like First and Next which don't notify the OnDataChange event?
