Is there an InnerException that would give more information as to what is wrong?
It could be a config problem, like IncludeDetailGrids set to true and DetailGridsMode set to Joined on the ExcelExporter, but SynchronizeDetailGrids set to false on the GridControl.
It could be a access permission problem on the underlying file of the stream (the “C:\test.xml” ).
It could be a bug.
