Hi, 

Did you manage to solve this problem ? I am experiencing the same issue, that when I reorder columns and then export to excel, it wil crash with the same error as mentioned above...

Hello Peter,

Did you try the sample provided from my colleague Daniel? If you did not, then could you check it and let me know how it differs from your real setup?

All the best,

Hi, 

I will try that within few days, because I have another problem with master-detail grid, so I am creating small page with only that grid, so I can test the functionality and then implement it into our huge project, where are hundreds lines of source code... 

I will let you know, how was my progress... 

Thanks anyway

Hi Daniel,

I am also facing the same issue and the attached Demo (Export-Reorder.rar) is not working as expected.
Note: After reorder if I click on 'Save Position' and then do export, it is wokring properly.

Kindly provide the solution or other demo for this issue.

Hello Nileshkumar,

I prepared a video which demonstrates how the Export-Reorder sample work on my side. On the sample has only one button which exports the grid. Could you please let me know what kind of control is "Save Position" as I was unable to find it in the sample?
