I am trying to use Spread (version 2.5) from FarPoint Technologies. It is a spreadsheet control. Unfortunately, it does not come with an AVG function. However, the documentation says that you can define custom formulas and functions. I can define the custom function name with the AddCustomFunction method. I also have placed the cusom function into a cell. I have also defined the function in the CustomFunction event. What I cannot get to happen is the CustomFunction event to fire.

Has anybody had any success doing this with Spread?
