Posted 21 August 2018, 3:44 pm ESTHello,
We upgraded our production web server and now all of the cells in our sheets are rendering as black unless we specifically modify the cell's color in code. Previously, the control used the colors from the template XLSX file. In our template, we mostly have grey or "no fill" and those show up black. If I change the color to red or something, that seems to work. Changing it back to grey shows black again.
Any ideas about what is missing or how to fix this without coloring every cell individually?
OLD: Windows Server 2008 R2, Excel 2010, Spread 9
NEW: Windows Server 2016, Excel 2013, Spread 9
We see the black cells whether we deploy an old version with Spread 9 or a new one with Spread 11.
