We are just about to order Aspose.Excel but I’m not sure now whether we will be able to drill through using it. Currently the user can click on a cell in the datagrid which will bring up a smaller window with a “drill through” of data related to the cell that was clicked.
Is that possible?
I am also not sure about this issue. Aspose.Excel is a spreadsheet creation engine without UI. The generated spreadsheet is viewed in MS Excel or other Excel viewer. So I think this feature depends on the viewers.
