I have a problem when I try to export the OladGrid to Excel.
When I launch the export:
1) are not retained styles that imposed on the Grid (colors, text size, etc.);
2) are not exported correctly rows / columns when I expand all.
I also tried to change the code of your example "DataTableSupportDemo" to put the export to Excel by copying it from your example "GridExportData", but I get the same error that I have in my application.
I attach the export file that I receive by exporting your example.
What can I do to fix it?
