I'm storing values in a series of arrays that are updated continously. I'll create a GUI with a series of custom controls to display all the different types of data for each entry.

If I want to run some kind of continuous scan or loop, checking for a certain conditions and then update my display accordingly, what would be the best way to do it? For example, if I've a group of integers in an array with lots of columns and rows, and I want to display something, or send values to a method for further calculation, when ((Row2Col5 - Row4Col10) >= Row15CCol20) (for example), what's the best way to do this?

With an event? A loop? Check the condition when some kind of OnArrayCellChangedEvent or something?

Thanks in advance,

Tom.
