Hello Georgi,

My current installed version - 12.1.20121.2038

I'm still having the same issue, in the meantime to resolve the issue I commented the below line which causing the issue...

workSheet.PrintOptions.InsertPageBreak(workSheet.Rows[headerRow]);

Can you please try creating the excel file dynamically and also add data at runtime and format – Insert Page break at rows/column level. As I said earlier I’m seeing this issue when I’m having more than 65k rows in my output excel file.

Thanks

Hello vbalingula,

I try to reproduce this issue using bigger excel file (in my test I`m using file with size 260 Kb), but again everything works properly. Could you please tell me what exact is your current build of version 12.1. I`m using 12.1.20121.2054. If you are using older build, please download the latest available service release from our site:

Infragistics.com -> Accounts -> My Keys and Downloads

Please take a look at the attached video file with my tests with bigger file. Please let me know if you have any questions.

Regards

I am using version 12.1

Hello,

Thank you for your quick reply and sample code.

Sorry I forgot to mention - but I noticed that when I have rows fewer then 65K I don’t see that issue but more then that it started causing the issue!
