There are two problems.

1. I have add-in formulas that I process with a class that implements Aspose.Cells.ICustomFunction. However if I set the .Value property of a cell it wipes out the formula associated with that cell.

2. If I save a workbook, then the Value of all of all the formula cells is reset to nothing.

I need a way to have both the value and the formula be saved when the workbook is saved, basically I need custom formulas to behave the same way as standard formulas, aside from the fact that I have to calculate the values.

We have clients that are waiting for the solution, thank you
