Hi,

I'm trying to use the UltraGridExcelExporter to export a grid to excel. It works if there's data in the grid, but if it is empty, it fails with this error:

System.Collections.Generic.KeyNotFoundException was caught
  Message="The given key was not present in the dictionary."

InnerException:

Is it possible to at least export the column headers even though there are no rows in the grid?
