Great, thanks very much.

Do you know how we’d support adapting formulas as they’re copied? I’m copying say, row 1 to row 2 and want to include the formula. So the original formula might be sum(A1:K1) for row 1 and now I want my row 2 (copy) to have sum(A2:K2).

At the moment, it copies the formula verbatim so I get both using sum(A1:K1) for example.

Any ideas?
Cheers

It seems that NPOI has been slightly refactored. Now it use IRow and ICell instead of HSSFRow HSSFCell classes. The rest works just fine. Thank you for sharing the code.

Hi Zach,

Is there a way for us to get your complete NPOI custom helper class? Couldn’t find it anywhere. :)

Thanks.

In the routine for the copy, I’m assuming your copying a standard row of standalone data. It looks like your copying a row that is associated with an aggregate (Sum, Count, Min, Max, etc…). I’m not sure how to do this off the top of my head, but it may be as easy as copying some additional aggregate properties about the row.

I am trying your code and getting the following error.

Unable to cast object of type ‘NPOI.HSSF.Record.Aggregates.DataValidityTable’ to type ‘NPOI.HSSF.Record.Record’.

Any idea what might be causing this?
