I have a grid that uses the UltraWebGridExcelExporter.Export(UltraWebGrid, ExcelWorkbook) method, and worked until this morning. I can't find anything that has changed in the configuration of the grid, but the method call above returns this exception:
System.ArgumentOutOfRangeException: Outline level must be between 0 and 7. Parameter name: value Actual value was 8.
There are no manual settings for OutlineLevel and it is not a hierarchical or grouped grid.
Any ideas on why I'm getting this exception?
Thanks,
Jeff
