    I have gridview in which I added some common group headers to group the columns logically. Depending on the context some of these logical groups have no data and therefore I hide them in the UI (IsVisible=false on DataLoaded event). On exporting the grid to Excel (.ExportToXlsx method) the Group Headers does not line up with the relevant columns. I put this down to the hidden columns so my solution was to first show all the columns (IsVisible=true), do the export and then hide the relevant empty columns again. However, now none of the group headers are exported.

     I capture the ElementExportingToDocument event and can see a CommonColumnHeaderRow element being exported but no CommonColumnHeaderCell element or the like (next element is HeaderRow).

    Any thoughts?

    I have moved showing all columns to before calling the FileDialog for the destination and now it works as expected. So it seems like a timing issue.

    While this addresses my workaround, ideally I would like not to export the empty columns but be able to keep the headers lined up
