Hi CB,
I tried to reproduce the issue using this sample.
http://websamples.syncfusion.com/samples/XlsIO.Windows/62927/main.htmBut I was not able to reproduce the issue. Could you please take a look at the sample above and let me know if the problem still exists? If not could you please modify this sample so that I can reproduce the issue? This would help me in analyzing this issue further.
Thanks,
Melba
